Glenohumeral dysplasia can occur in brachial plexus birth palsy due to an imbalance of muscle forces. Most commonly this occurs in C5-C6 injuries where the shoulder external rotators are weak compared with the shoulder internal rotators. Treatment of the dysplasia with open reduction of the glenohumeral joint in combination with rebalancing the muscles can improve the development of the joint. Furthermore, the tendon transfer can improve shoulder function by decreasing the internal rotation forces about the shoulder while increasing the external rotation forces...

We investigated age-related change in the contribution of stroke volume (SV) to central PP (cPP). Eighty seven adult subjects who were free of vasoactive agents were included. Subjects were divided into three age groups: young (20-39 years, n = 26), middle (40-49 years, n = 29), and old (≥50 years, n = 32). SV was calculated by Doppler echocardiography. Hemodynamic indices were measured using a brachial cuff-based oscillometric method. The brachial and cPP showed a small decline from the young group to the middle group and a greater rise after 50 years old...

BACKGROUND: Neuronal death may be an overlooked and unaddressed component of disability following neonatal nerve injuries, such as obstetric brachial plexus injury. N-acetylcysteine and acetyl-L-carnitine improve survival of neurons after adult nerve injury, but it is unknown whether they improve survival after neonatal injury, when neurons are most susceptible to retrograde neuronal death. The authors' objective was to examine whether N-acetylcysteine or acetyl-L-carnitine treatment improves survival of neonatal motor or sensory neurons in a rat model of neonatal nerve injury...

INTRODUCTION: Guillain-Barre syndrome is classically defined as a symmetrical ascending acute polyradiculoneuropathy, although there are atypical variants that make diagnosis difficult. CASE REPORTS: The medical data of six patients in our hospital area are collected during the first quarter of 2013. Lumbar punctures, imaging, neurophysiological studies, ganglioside antibodies and serologies have been proposed in all cases. We focus on the atypical features as late hyporeflexia, increased frequency of asymmetry and distal paresis and initial fever...

BACKGROUND: Snakebite is a health issue specific to some parts of the world, especially in the tropical area, where it produces many victims. The main clinical damage caused by snake bite involves hemotoxic, neurotoxic and myotoxic reactions. It is also established that the importance of systemic impairment varies according to individual factors and are related to organ dysfunction, shock or hypotension. We report the case of a young woman suffering from snakebite who developed deep vein thrombosis and compartment syndrome...

Implanted venous access device (IVAD) late dysfunction is commonly caused by fibrin sheath formation. The standard method of endovascular fibrin sheath removal is performed via the femoral vein. However, it is not always technically feasible and sometimes contraindicated. Moreover, approximately 4-6 h of bed rest is necessary after the procedure. In this article, we describe an alternative method of fibrin sheath removal using the brachial vein approach in a young woman receiving chemotherapy for breast cancer...

Recent reports have demonstrated that nearly two-thirds of the world's population do not have access to adequate surgical care, a burden that is borne disproportionately by residents of resource-poor countries. Although the reasons for limited access to surgical care are complex and multi-factorial, among the most substantial barriers is the lack of trained surgical providers. This is particularly true in surgical subspecialties that focus on life-improving, rather than life-saving, treatments, such as pediatric hand and upper extremity surgery, which manages such conditions as congenital malformations, trauma and post-traumatic deformities including burns, and neuromuscular conditions (brachial plexus birth palsy, spinal cord injury, and cerebral palsy)...

Study Design Retrospective cohort study. Objective Supination deformity in obstetric brachial plexus injury can have debilitating consequences for the functionality of the hand. Surgical treatment by a forearm osteotomy has a recurrence rate of 20 to 42%. As a complement to forearm osteotomy, a biceps rerouting may improve outcome. Methods Children with residual brachial plexus injury, who had a forearm osteotomy for a supination contracture and had a postoperative decrease of pronation to 50 degrees or less, were indicated for a biceps rerouting...

OBJECTIVES: The current study addressed the hypothesis that the local decrease in endothelin-1 (ET-1) bioavailability during sustained flow increases contributes to endothelium-dependent, flow-mediated dilatation (FMD) of conduit arteries and is altered in presence of cardiovascular risk factors. METHODS AND RESULTS: In nine young healthy individuals, the decrease in local ET-1 plasma levels and radial artery FMD in response to hand skin heating (from 34 to 44 °C) was not affected by endothelin type A (ETA) receptor blockade, achieved using the brachial infusion of BQ-123 (100 nmol/min per l of forearm), as compared with physiological saline (0...

BACKGROUND: Non-invasive limb hemodynamics may aid in diagnosis of critical limb ischemia (CLI), although the relationship with disease severity and response to endovascular therapy is unclear. METHODS AND RESULTS: This prospective, single-center study enrolled 100 CLI patients (Rutherford class 4-6) who underwent infrapopliteal endovascular revascularization (175 lesions) in the Peripheral RegIstry of Endovascular Clinical OutcoMEs (PRIME) registry. Hemodynamic measures included ankle-brachial index (ABI), toe-brachial index (TBI), and toe pressure (TP)...

The cardio-ankle vascular index (CAVI) represents a promising index of arterial stiffness. However, neither the CAVI measure nor its measurement device, the VaSera, have undergone general testing in a North American clinical setting. To begin the process of collecting normal values in the United States, we studied 20 male and 28 female volunteers without reported cardiovascular or renal disease and no history of smoking. Their CAVIs, ankle-brachial indices (ABIs), and four-limb blood pressures were measured in three positions: supine, 7° Trendelenburg, and 7° reverse Trendelenburg...

We examined whether there is a difference in compliance between the deep and superficial conduit veins of the upper arm in response to prolonged exercise. Eight young men performed cycling exercise at 60% of peak oxygen uptake until rectal temperature had been increased by 1.1°C for 38-48 min. The cross-sectional area (CSA) of the brachial (deep) and basilic (superficial) veins was assessed by ultrasound during a cuff deflation protocol. Compliance (CPL) was calculated as the numerical derivative of the cuff pressure and CSA curve...

An individual participant data meta-analysis was conducted in the data of 14 673 Japanese participants without a history of cardiovascular disease (CVD) to examine the association of the brachial-ankle pulse wave velocity (baPWV) with the risk of development of CVD. During the average 6.4-year follow-up period, 687 participants died and 735 developed cardiovascular events. A higher baPWV was significantly associated with a higher risk of CVD, even after adjustments for conventional risk factors (P for trend <0...

The management of pink pulseless limbs in supracondylar fractures has remained controversial, especially with regards to the indication for exploration in a clinically well-perfused hand. We reviewed a series of seven patients who underwent surgical exploration of the brachial artery following supracondylar fracture. All patients had a non-palpable radial artery, which was confirmed by Doppler ultrasound. CT angiography revealed complete blockage of the artery with good collateral and distal run-off. Two patients were more complicated with peripheral nerve injuries, one median nerve and one ulnar nerve...
