Description

A 73-year-old woman with hypertension and atrial fibrillation presented with head and neck injury after mechanical fall. During workup, chest X-ray anteroposterior view (figure 1) revealed a rounded opacity silhouetting the left heart border and hilum. Subsequent contrast-enhanced CT of the chest showed single, 6.4 cm, rounded, well-defined, thin-walled, non-enhanced, low attenuated (–20 and 20 Hounsfield Unit) and homogenous cyst-like structure at the left mediastinum connected to pericardial recesses and not attached to adjacent structures (figure 2A–C). Transthoracic echocardiogram ruled out left ventricular aneurysm, aortic aneurysm, solid tumour and outflow tracts obstruction. Although bronchogenic cyst, oesophageal duplication cyst, thymic tumour and mediastinal lymphoma were considered as possible differentials, radiological features such as CT appearance, homogenous attenuation, unrelated to the underlying structures favoured pericardial cyst. Since patient was asymptomatic, patient and family member were unwilling to undergo surgical removal and pathological confirmation. Follow-up with non-enhanced CT of...

Description

A previously healthy 29-year-old Mexican woman presented to an emergency department with transient hemiparaesthesias and dysarthria. There was no evidence of stroke on cross-sectional imaging of the head, and she was discharged without a clear diagnosis. Two days later, she returned with acute abdominal pain. Abdominal imaging revealed complete occlusion of the right renal artery, prompting emergency embolectomy. Following the procedure, she developed acute haemoptysis, dyspnoea and hypoxaemia. Chest imaging demonstrated evidence of pulmonary venous hypertension. Cardiac auscultation revealed an opening snap followed by a diastolic murmur with presystolic accentuation. These sounds were better appreciated in combination with phonocardiography, a technique supplanted by echocardiography in the 1970s1 that visualised heart sounds (video 1). An echocardiogram confirmed the presence of mitral stenosis (MS), unifying the syndrome of embolic phenomena, haemoptysis and pulmonary hypertension. She underwent successful mitral valve replacement and has since returned to normal...

Muscle Bioenergetic Considerations for Intrinsic Laryngeal Skeletal Muscle Physiology

Purpose

Intrinsic laryngeal skeletal muscle bioenergetics, the means by which muscles produce fuel for muscle metabolism, is an understudied aspect of laryngeal physiology with direct implications for voice habilitation and rehabilitation. The purpose of this review is to describe bioenergetic pathways identified in limb skeletal muscle and introduce bioenergetic physiology as a necessary parameter for theoretical models of laryngeal skeletal muscle function.

Method

A comprehensive review of the human intrinsic laryngeal skeletal muscle physiology literature was conducted. Findings regarding intrinsic laryngeal muscle fiber complement and muscle metabolism in human models are summarized and exercise physiology methodology is applied to identify probable bioenergetic pathways used for voice function.

Results

Intrinsic laryngeal skeletal muscle fibers described in human models support the fast, high-intensity physiological requirements of these muscles for biological functions of airway protection. Inclusion of muscle bioenergetic constructs in theoretical modeling of voice training, detraining, fatigue, and voice loading have been limited.

Conclusions

Muscle bioenergetics, a key component for muscle training, detraining, and fatigue models in exercise science, is a little-considered aspect of intrinsic laryngeal skeletal muscle physiology. Partnered with knowledge of occupation-specific voice requirements, application of bioenergetics may inform novel considerations for voice habilitation and rehabilitation.

Congenital Deafness Alters Sensory Weighting for Postural Control.

Objectives: The aim of this study was to examine sensory reweighting for postural control in congenitally deaf individuals. Design: We studied 14 controls and 14 deaf age-matched individuals using a force platform and the modified clinical test of sensory interaction and balance protocol. Both groups performed the postural tasks without auditory cues (with hearing protectors for controls or without hearing devices for the deaf). Results: The results confirmed poorer postural stability in the deaf. More importantly, the data suggest that congenitally deaf individuals rely more on somatosensory information for postural control than controls. Conclusions: This increased somatosensory reliance may increase postural sway when it comes to more challenging postural conditions. Copyright (C) 2017 Wolters Kluwer Health, Inc.
