Cortical Frontoparietal Network Dysfunction in -Frontotemporal Dementia.

A rare cause of inherited frontotemporal dementia (FTD) is a mutation in the gene on chromosome 3 leading to the autosomal dominantly inherited FTD (-FTD). Since -FTD is clinically well-characterized, and patients show a distinct pattern of executive dysfunction, the condition offers possible insight in the early electroencephalographic (EEG) changes in the cortical networks. Specifically, EEG microstate analysis parses the EEG signals into topographies believed to represent discrete network activations.

Joint Mobility and Physical Function of Danish Hemophilia Patients: A Three-Wave Panel Study Spanning 24 Years.

Background: The positive effects of factor treatment of hemophilia are well established, but the long-term outcomes are not well documented. This panel study evaluated changes in bleeding frequency, joint mobility, physical function, and symptoms in Danish patients with moderate to severe hemophilia A or B over 24 years.

Methods: Three anonymous surveys were conducted in 1988, 2001, and 2012 targeting Danish patients with moderate to severe hemophilia, and the study participants, respectively, were 128, 156, and 164 male patients with hemophilia (PWH).

A Prospective Comparative Study of Parathyroid Dual-Phase Scintigraphy, Dual-Isotope Subtraction Scintigraphy, 4D-CT, and Ultrasonography in Primary Hyperparathyroidism.

Purpose: Preoperative localization of the diseased parathyroid gland(s) in primary hyperparathyroidism allows for minimally invasive surgery. This study was designed to establish the optimal first-line preoperative imaging modality.

Patients And Methods: Ninety-one patients were studied consecutively in a prospective head-to-head comparison of dual isotope (Tc-MIBI vs I) subtraction parathyroid scintigraphy (PS), dual-phase PS, 4-dimensional (4D) CT, and ultrasonography (US).

Scintigraphic assessment of retrograde colonic washout in fecal incontinence and constipation.

Purpose: This study aimed to evaluate the colorectal luminal transport obtained by retrograde colonic washout with a new scintigraphic technique.

Methods: Nineteen patients (5 with spinal cord lesion, 6 with idiopathic fecal incontinence, and 8 with idiopathic constipation) treated with retrograde colonic washout took indium-111-labeled polystyrene pellets to label the bowel contents. Technetium-99m-diethylene-triamine-pentaacetic acid was mixed with the irrigation fluid to assess its extent within the colorectum.
