BACKGROUND: Few studies were performed to compare ultrasound guided brachial plexus block with procedural sedation for reduction of shoulder dislocations in the Emergency Department (ED). This study was done to provide further evidence regarding this comparison. METHODS: This was a randomized clinical trial performed on patients presenting with anterior shoulder dislocations to the emergency department of an academic level 2 trauma center. Exclusion criteria were any contraindications to the drugs used, any patient which may not be potentially assigned into both groups because of an underlying medical condition, presence of neurovascular compromise related to the dislocation, presence of concomitant fractures, and patient refusal to participate in the study...

Accessory respiratory muscles help to maintain ventilation when diaphragm function is impaired. The following protocol describes a method for repeated measurements over weeks or months of accessory respiratory muscle activity while simultaneously measuring ventilation in a non-anesthetized, freely behaving mouse. The technique includes the surgical implantation of a radio transmitter and the insertion of electrode leads into the scalene and trapezius muscles to measure the electromyogram activity of these inspiratory muscles...

This case report describes a 29-year-old male who presented with immediate onset of Horner's syndrome and ipsilateral brachial plexopathy after sleeping with his arm dangling outside a car window for 8 h. Outside workup and imaging revealed rhabdomyolysis of the left neck musculature. Subsequent electrodiagnostic testing and high-resolution brachial plexus magnetic resonance imaging at the authors' institution attributed the Horner's syndrome and concurrent brachial plexopathy to rhabdomyolysis of the longus colli and scalene musculature, which had compressed-and consequently scar tethered-the cervical sympathetic trunk and brachial plexus...

[Purpose] This study examined the effects of manipulation of the thorax and the intensity of the pressure biofeedback unit on the superficial cervical flexors muscle during craniocervical flexion exercise. [Subjects and Methods] Thirty three subjects participated in the experiment. Thirty three healthy people without any orthopedic history were also selected. The subjects could monitor the pressure applied to cervical vertebra 3 of the craniocervical junction by markings on the pressure biofeedback unit. Craniocervical flexion exercise was performed for 20 seconds per pressure, and two minutes of rest was allowed after exercise to reduce muscle fatigue...

Inspiratory muscle training (IMT) has consistently been shown to reduce exertional dyspnea in health and disease; however, the physiological mechanisms remain poorly understood. A growing body of literature suggests that dyspnea intensity can largely be explained by an awareness of increased neural respiratory drive, as indirectly measured using diaphragmatic electromyography (EMGdi). Accordingly, we sought to determine if improvements in dyspnea following IMT can be explained by decreases in inspiratory muscle EMG activity...

Scapular winging secondary to dorsal scapular nerve (DSN) damage is an underestimated condition. It is often caused by entrapment of the nerve due to a hypertrophic middle scalene muscle, or by stretching of the DSN during traumatic movements. The condition has also been attributed to myofascial pain syndrome of the rhomboids with entrapment of the DSN. The non-specific symptomatology reported by patients is often incorrectly diagnosed, and this can result in a high level of disability of the upper limb. A clinical case of misdiagnosed dorsal scapula entrapment is presented...

Imminent neuromuscular respiratory failure is recognized by shortness of breath, restlessness, and tachycardia and is often followed by tachypnea, constantly interrupting speech, asynchronous breathing and sometimes paradoxical breathing and use of scalene and sternocleidomastoid muscles. Once a patient presents with such a constellation of signs, there are some difficult decisions to be made and include assessment of the severity of respiratory failure and in particular when to intubate. Failure of the patient to manage secretions as a result of oropharyngeal weakness rather than neuromuscular respiratory weakness may be another reason for acute intubation...

INTRODUCTION: High-intensity noninvasive ventilation (NIV) has been shown to improve outcomes in stable chronic obstructive pulmonary disease patients. However, there is insufficient knowledge about whether with this more controlled ventilatory mode optimal respiratory muscle unloading is provided without an increase in patient-ventilator asynchrony (PVA). PATIENTS AND METHODS: Ten chronic obstructive pulmonary disease patients on home mechanical ventilation were included...

INTRODUCTION: Neurogenic thoracic outlet syndrome (nTOS) is the most common manifestation of thoracic outlet syndrome (TOS), accounting for more than 95% of cases. It is usually caused by cervical ribs, anomalies in the scalene muscle anatomy or post-traumatic inflammatory changes causing compression of the brachial plexus. CASE PRESENTATION: We present an unusual case of nTOS caused by a cystic lymphangioma at the thoracic outlet, with only one case reported previously in the literature...

BACKGROUND: Cervical ribs have been reported to be present in about 0.5% of the general population, 10% of patients with cervical rib who are symptomatic usually have neurogenic symptoms, but some have arterial symptoms. In 1861, Coote was the first to excise a cervical rib through a supraclavicular approach and relieved the symptoms of thoracic outlet syndrome. OBJECTIVE: In this study, we address the efficacy and safety of a modification to the supraclavicular approach for resection of symptomatic cervical ribs...

BACKGROUND: Transaxillary approach to first rib resection and scalenectomy (TAFRRS) is a well-established technique for treatment of thoracic outlet syndrome (TOS). Although anatomic features encountered during TAFRRS are in general constant, vascular anomalies may be encountered but have not been described to date. Herein we describe vascular abnormalities encountered during TAFRRS. METHODS: We performed a retrospective review of a prospective practice database of 224 operations for TOS performed in 172 patients from March 2000 to March 2014...

Herein, we demonstrate how the supramolecular complexity (evaluated by the degree of self-sorting M) evolves in a chemical cycle of cascaded metallosupramolecular transformations, using abiological self-assembled entities as input signals. Specifically, the successive addition of the supramolecular self-assembled structures S1 and (T2 + S2) to the starting supramolecular two-component equilateral triangle T1 (M = 1) first induced a fusion into the three-component quadrilateral R1 (M = 6) and then to the five-component scalene triangle T3 (M = 16)...

Described in this article is diagnosis and treatment of mixed type of thoracic outlet syndrome (TOS) resulting from scalene muscle hypertrophy. Many diseases should be considered in the differential diagnosis to definitively diagnose this syndrome, and it is necessary to ask about activities of daily life, in addition to adding provocative tests to physical examination and examining electrophysiological and imaging results. Once diagnosed, even if complaints decrease with conservative treatment, surgery may be required...

Compression of the dorsal scapular nerve (DSN) is associated with pain in the upper extremity and back. Even though entrapment of the DSN within the middle scalene muscle is typically the primary cause of pain, it is still easily missed during diagnosis. The purpose of this study was to document the DSN's anatomy and measure the oblique course it takes with regard to the middle scalene muscle. From 20 embalmed adult cadavers, 23 DSNs were documented regarding the nerve's spinal root origin, anatomical route, and muscular innervations...

Thoracic outlet syndrome (TOS) is a group of disorders all having in common compression at the thoracic outlet. Three structures are at risk: the brachial plexus, the subclavian vein, and the subclavian artery, producing neurogenic (NTOS), venous (VTOS), and arterial (ATOS) thoracic outlet syndromes, respectively. Each of these three are separate entities, though they can coexist and possibly overlap. The treatment of NTOS, in particular, has been hampered by lack of data, which in turn is the result of inconsistent definitions and diagnosis, uncertainty with regard to treatment options, and lack of consistent outcome measures...
