Vocal Cord Dysfunction During the COVID-19 Pandemic.

Background: Vocal cord dysfunction is an upper-airway disorder characterized by exaggerated and transient glottic constriction causing respiratory and laryngeal symptoms. Common presentation is with inspiratory stridor often in the context of emotional stress and anxiety. Other symptoms include wheezing (which may be on inspiration), frequent cough, choking sensation, or throat and chest tightness.

Superior vena caval thrombosis after a neonatal arterial switch procedure.

Superior vena cava (SVC) and inferior vena cava obstructions were once well-documented complications from the Mustard repair for D-transposition of the great arteries (TGA), occurring in 10%-40% patients; however, they are rarely documented with the current, more common arterial switch operation (ASO). Similarly, SVC thrombosis is an uncommon, severe complication following neonatal cardiac surgery. We report a case of persistent SVC thrombosis, SVC syndrome, and chylothorax arising after ASO, refractory to thrombolysis and stent placement.

A Mixed Methods Small Pilot Study to Describe the Effects of Upper Limb Training Using a Virtual Reality Gaming System in People with Chronic Stroke.

. This small pilot study aimed to examine the feasibility of an upper limb rehabilitation system (the YouGrabber) in a community rehabilitation centre, qualitatively explore participant experiences, and describe changes after using it. .

Morphological and mitochondrial DNA characters for identification and phylogenetic analysis of the myiasis-causing flesh fly Wohlfahrtia magnifica and its relatives, with a description of Wohlfahrtia monegrosensis sp. n. Wyatt & Hall.

Wohlfahrtia magnifica (Schiner) (Diptera: Sarcophagidae) is a major cause of traumatic myiasis in livestock in Central and Eastern Europe and in countries bordering the Mediterranean. The present study explored the utility of external body characters, genitalia characters and mitochondrial DNA characters for identification of this and related species in the subfamily Paramacronychiinae. Sequence analyses of the 3' terminal 273 bp of the mitochondrial cytochrome b gene revealed two lineages of W.

Old World screwworm fly, Chrysomya bezziana, occurs as two geographical races.

A morphological and molecular analysis was undertaken with the objective of identifying markers for geographical populations of Old World screwworm flies, Chrysomya bezziana Villeneuve (Diptera: Calliphoridae). The morphological analysis involved 192 adult flies from 14 countries, and the molecular analysis involved 45 larvae or adults from 14 populations in 11 countries. Principal components and cluster analysis of 10 morphological characters indicated that flies from Papua New Guinea (PNG) were a distinct group and most similar to flies from nearby Asian islands (Java, Sabah).
