Inhibition of Manual Movements at Speech Arrest Sites in the Posterior Inferior Frontal Lobe.

Neurosurgery 2018 Dec 12. Epub 2018 Dec 12.

Department of Neurological Surgery, University of California San Francisco, San Francisco, California.

Background: Intraoperative stimulation of the posterior inferior frontal lobe (IFL) induces speech arrest, which is often interpreted as demonstration of essential language function. However, prior reports have described "negative motor areas" in the IFL, sites where stimulation halts ongoing limb motor activity.

Objective: To investigate the spatial and functional relationship between IFL speech arrest areas and negative motor areas (NMAs). Read More

Machine learning-based prediction of clinical pain using multimodal neuroimaging and autonomic metrics.

Pain 2018 Oct 17. Epub 2018 Oct 17.

Department of Radiology, Athinoula A. Martinos Center for Biomedical Imaging, Massachusetts General Hospital, Harvard Medical School, Charlestown, MA, United States.

Although self-report pain ratings are the gold standard in clinical pain assessment, they are inherently subjective in nature and significantly influenced by multidimensional contextual variables. Although objective biomarkers for pain could substantially aid pain diagnosis and development of novel therapies, reliable markers for clinical pain have been elusive. In this study, individualized physical maneuvers were used to exacerbate clinical pain in patients with chronic low back pain (N = 53), thereby experimentally producing lower and higher pain states.

Brain structural networks and connectomes: the brain-obesity interface and its impact on mental health.

Neuropsychiatr Dis Treat 2018 26;14:3199-3208. Epub 2018 Nov 26.

Department of Psychiatry, Chang Gung Memorial Hospital, Chiayi, Taiwan,

Purpose: Obesity is a complex and multifactorial disease identified as a global epidemic. Convergent evidence indicates that obesity differentially influences patients with neuropsychiatric disorders providing a basis for hypothesizing that obesity alters brain structure and function associated with the brain's propensity toward disturbances in mood and cognition. Herein, we characterize alterations in brain structures and networks among obese subjects (ie, body mass index [BMI] ≥30 kg/m) when compared with non-obese controls. Read More

Posterior staphyloma in pathologic myopia.

Prog Retin Eye Res 2018 Dec 8. Epub 2018 Dec 8.

Department of Ophthalmology, Medical Faculty Mannheim, Ruprecht-Karls-University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167, Mannheim, Germany. Electronic address:

A posterior staphyloma is an outpouching of a circumscribed region of the posterior fundus and has been considered a hallmark of pathologic myopia. Occurring in highly myopic eyes, it is histologically characterized by a relatively abrupt scleral thinning starting at the staphyloma edge, a pronounced de-arrangement of scleral collagen fibrils and a marked choroidal thinning, which is the most marked at the staphyloma edge and which occurs in addition to the axial elongation-associated choroidal thinning. Besides in highly myopic eyes, a posterior staphyloma can be found in non-highly myopic eyes in association with retinitis pigmentosa or localized defects of Bruch's membrane in the cases of which it is not associated with a marked choroidal thinning.

Foot type has been associated with pain, injury, and altered gait mechanics. Morphological variations in foot bones due to foot type variation may impact surgical and therapeutic treatments. The purpose of this study was to utilize principal component analysis (PCA) to determine how morphology of the hind- and midfoot bones differs among foot types and sex. Read More

Recommendations for Iliosacral Screw Placement in Dysmorphic Sacrum based on Modified In-Out-In Corridors.

J Orthop Res 2018 Dec 11. Epub 2018 Dec 11.

Clinic of Orthopaedics and Sportsorthopaedics, Klinikum rd. Isar, Technische Universität München, Munich, Germany.

(1) Can iliosacral osseous corridor diameters in sacral dysmorphism be enlarged by in-out-in screw placement at the posterior iliosacral recessus? (2) Are lumbosacral transitional vertebra (LSTV) the anatomical cause for sacral dysmorphism? (3) Are there sex-specific differences in sacral dysmorphism? 594 multislice CT scans were screened for sacral dysmorphism and 55 data-sets selected. Each pelvis was segmented manually and cylindrical iliosacral corridors (S1 and S2 vertebra) were semi-automatically determined. Corridor trajectories, -diameters and -lengths were measured.

Angioplasty versus stenting for infrapopliteal arterial lesions in chronic limb-threatening ischaemia.

Cochrane Database Syst Rev 2018 Dec 8;12:CD009195. Epub 2018 Dec 8.

Department of Medical Imaging, Gold Coast University Hospital, 1 Hospital Blvd, Southport, Queensland, Australia, 4215.

Background: Chronic limb-threatening ischaemia (CLTI) is a manifestation of peripheral arterial disease (PAD) that includes chronic ischaemic rest pain or ischaemic skin lesions, ulcers, or gangrene for longer than two weeks. The severity of the disease depends on the extent of arterial stenosis and the availability of collateral circulation. Treatment for CLTI aims to relieve ischaemic pain, heal ischaemic ulcers, prevent limb loss, improve quality of life, and prolong survival. Read More

Saws, scissors and sharks: Late Paleozoic experimentation with symphyseal dentition.

Anat Rec (Hoboken) 2018 Dec 8. Epub 2018 Dec 8.

CR2P UMR 7207 (MNHN, CNRS, UPMC, Sorbonne Université), Département Origines et Evolution, Muséum National d'Histoire naturelle, CP 48, 57 rue Cuvier, F-75231 Paris cedex 05, France.

Sharks of Late Paleozoic oceans evolved unique dentitions for catching and eating soft bodied prey. A diverse but poorly preserved clade, edestoids are noted for developing biting teeth at the midline of their jaws. Helicoprion has a continuously growing root to accommodate more than 100 crowns that spiraled on top of one another to form a symphyseal whorl supported and laterally braced within the lower jaw.
