OBJECTIVES: To describe the radiological phenotype of HER2-mutant lung cancers on CT at presentation. METHODS: Eligible patients with lung adenocarcinomas with HER2 mutations were stage-matched with two control groups (EGFR- and KRAS-mutant groups). Evaluated CT features of the primary tumor included size, location, consistency, contour, presence of pleural tags and pleural retractions. Presence of pleural effusions, lung metastases, adenopathy, chest wall invasion, and were also recorded...

BACKGROUND: Neck pain has been associated with altered muscle activity and impaired kinematics. Patients frequently report pain during physiological neck movements. Previously, the average muscle activity during these movements has been measured. However, muscle activity is modulated by the position in the range of movement, hence the study of neck muscle activity in discrete sections of the range of movement is warranted. Evidence is conflicting regarding range of movement restriction in neck pain...

Background: Aggressive fibromatoses are histologically benign fibrous neoplasms originating from musculoaponeurotic structures throughout the body. They are locally invasive and erode adjacent vital structures. The head and neck region constitutes 7-25% of all extra-abdominal cases. Case Report: Here, we report the case of a patient with aggressive fibromatosis in the left side of the neck. While the tumor deeply invaded the scalene muscles, the lesion was successfully treated by surgery followed by radiotherapy...

This study examined sex differences in head kinematics and neck muscle activity during sudden head perturbations. Sixteen competitive ice hockey players participated. Three muscles were monitored bilaterally using surface electromyography: sternocleidomastoid (SCM), scalene (SCL) and splenius capitis (SPC). Head and thorax kinematics were measured. Head perturbations were induced by the release of a 1.5kg weight, attached to a wire wrapped around an adjustable pulley secured to the participant's head. Perturbations were delivered in 4 directions (flexion, extension, right and left lateral bend)...

BACKGROUND: It has been suggested that the quantification of paravertebral muscle composition and morphology (e.g. size/shape/structure) with magnetic resonance imaging (MRI) has diagnostic, prognostic, and therapeutic potential in contributing to overall musculoskeletal health. If this is to be realised, then consensus towards standardised MRI methods for measuring muscular size/shape/structure are crucial to allow the translation of such measurements towards management of, and hopefully improved health for, those with some musculoskeletal conditions...

OBJECTIVE: The transaxillary approach to thoracic outlet decompression in the presence of cervical ribs offers the advantage of less manipulation of the brachial plexus and associated nerves. This may result in reduced incidence of perioperative complications, such as nerve injuries. Our objective was to report contemporary data for a series of patients with thoracic outlet syndrome (TOS) and cervical ribs managed through a transaxillary approach. METHODS: We reviewed a prospectively maintained database for all consecutive patients who underwent surgery for TOS and who had a cervical rib...

Congenital anatomic anomalies and variations are frequent in the thoracic outlet and may be associated with clinical symptoms. Arterial thoracic outlet syndrome (TOS) is characterized by subclavian artery compression and vascular pathology, almost always in the presence of a bony abnormality. We describe here a patient with arterial thromboembolism following a fall on the outstretched arm, who was found to have subclavian artery stenosis and post-stenotic dilatation in the absence of a bony abnormality. Surgical exploration revealed a previously undescribed anomaly in which the subclavian artery passed through the costoclavicular space in front of the anterior scalene muscle, where it was subject to bony compression between the first rib and clavicle...

This study aimed to evaluate neuromuscular activation in the scalene and sternocleidomastoid muscles using surface electromyography (EMG) during progressively increased inspiratory flow, produced by increasing the respiratory rate under inspiratory-resistive loading using a mask ventilator. Moreover, we attempted to identify the EMG inflection point (EMGIP ) on the graph, at which the root mean square (RMS) of the EMG signal values of the inspiratory muscles against the inspiratory flow velocity acceleration abruptly increases, similarly to the EMG anaerobic threshold (EMGAT ) reported during incremental-resistive loading in other skeletal muscles...

BACKGROUND: Research investigating Whiplash Associated Disorder (WAD) has largely focused on the cervical spine yet symptoms can be widespread. Thoracic spine pain prevalence is reported ~66%; perhaps unsurprising given the forceful stretch/eccentric loading of posterior structures of the spine, and the thoracic spine's contribution to neck mobility/function. Approximately 50% WAD patients develop chronic pain and disability resulting in high levels of societal and healthcare costs. It is time to look beyond the cervical spine to fully understand anatomical dysfunction in WAD and provide new directions for clinical practice and research...

Professor Henryk Hilarowicz was a Polish surgeon who first described the technique of brachial plexus block performed in the interscalene groove between the anterior and middle scalene muscles. The article devoted to the technique appeared in the German-language journal Zentralblatt für Chirurgie in 1925, 45 years before Alon Winnie, who is widely regarded as the originator of this method, published his paper in Anesthesia & Analgesia in 1970.

Thoracic outlet syndrome (TOS) is a cause of upper extremity and shoulder dysfunction. TOS can present with a wide range of symptoms due to compression of the brachial plexus or its branches during their passage through the cervicothoracobrachial region or scalene triangle. There are three types of TOS: arterial, venous, and neurogenic. Neurogenic TOS (nTOS) is by far the most frequent type and represents more than 95% of all cases. Historically, surgical intervention for all types of TOS has evolved based on the treatment for a vascular etiology and has typically included a first rib resection...

Intramuscular hemangiomas (IMH) account for <%1 of all hemangiomas and are rarely located in the head and neck region. The most common site of origin in the head and neck is the masseter muscle, whereas IMH originating from the scalene muscles are rarely seen. Surgical excision of intramuscular hemangioma is considered the main treatment modality. Here we present the case of a male patient aged 17 with IMH that occured after blunt trauma in the supraclavicular region, fed by the thyrocervical and costocervical trunks, and with an arteriovenous shunt...
