REVIEW
Matthew Willsey, Thomas J Wilson, Phillip Troy Henning, Lynda J-S Yang
Offering real-time, high-resolution images via intraoperative ultrasound is advantageous for a variety of peripheral nerve applications. To highlight the advantages of ultrasound, its extraoperative uses are reviewed. The current intraoperative uses, including nerve localization, real-time evaluation of peripheral nerve tumors, and implantation of leads for peripheral nerve stimulation, are reviewed. Although intraoperative peripheral nerve localization has been performed previously using guide wires and surgical dyes, the authors' approach using ultrasound-guided instrument clamps helps guide surgical dissection to the target nerve, which could lead to more timely operations and shorter incisions...

BACKGROUND: Trauma is the main cause of morbidity and mortality in the pediatric population. Blunt trauma to the abdomen accounts for the majority of abdominal injuries in children. Pancreatic injury, although uncommon (2 to 9%), is the fourth most common solid organ injury. Unlike other solid organ injuries, pancreatic trauma may be subtle and difficult to diagnose. Computed tomography currently is the imaging modality of choice. As the incidence of pancreatic injury in children sustaining blunt abdominal trauma is low, management remains a challenge...

As dysfunction of the vascular system is an early, modifiable step in the progression of many cardiovascular diseases, there is demand for methods to non-invasively monitor the health of the vascular system in clinical and research settings. Validated by very good agreement with more technical assessments of vascular function, like intra-arterial drug infusions and flow mediated dilation (FMD), the passive leg movement (PLM) technique has emerged as a powerful, yet relatively simple, test of peripheral vascular function...

Iris cysts, both primary and secondary, are a diagnostic and a treatment challenge. Primary cysts arise either from the iris pigment epithelium or the iris stroma. Posterior pigment epithelial cysts are subdivided according to their location as central, midzonal and peripheral. Iris stromal cysts are classified either as congenital or acquired. Free floating cysts are usually dislodged pigment epithelial cysts. Secondary cysts are classified according to the underlying cause as implantation cysts, drug-induced, uveitic, tumor-induced, parasitic, or as cysts associated with systemic disorders...

Measurement of high acoustic pressures is necessary in order to fully characterise clinical high-intensity focused ultrasound (HIFU) fields, and for accurate validation of computational models of ultrasound propagation. However, many existing measurement devices are unable to withstand the extreme pressures generated in these fields, and those that can often exhibit low sensitivity. Here, a planar Fabry-Pérot interferometer with hard dielectric mirrors and spacer was designed, fabricated, and characterised and its suitability for measurement of nonlinear focused ultrasound fields was investigated...

BACKGROUND: The European Association of Cardiology (ESC) Guidelines on the diagnosis and treatment of acute heart failure (AHF) indicate prompt therapy initiation and performance of relevant investigations as paramount. Specifically, echocardiography prior to treatment is advocated only with hemodynamic instability, and the evaluation of clinical signs of peripheral perfusion and congestion is suggested as guidance for early interventions. Given the growing body of evidence on the diagnostic/monitoring capabilities of bedside ultrasound (including focused cardiac ultrasound, comprehensive echocardiography, lung ultrasound), we discuss the potential benefit of an integrated clinical/ultrasound approach at the very early stages of acute heart failure...

Pseudolymphoma is a drug reaction to anti-epileptics that is well recognized in humans; it has been reported in one cat but not dogs. In this report, lymphoma-like clinical signs are suspected to be secondary to phenobarbital administration in a dog. A 2.5-year-old male, neutered Shepherd mix presented for a 3-day history of progressive ataxia, dazed mentation, pyrexia, and lethargy. While hospitalized, the dog developed generalized lymphadenopathy and sustained pyrexia. The dog was receiving levetiracetam and phenobarbital for epilepsy, and serum concentrations of both were within standard therapeutic ranges...

Abdullah M Al Wahbi
BACKGROUND: Endoluminal laser ablation is now considered the method of choice for treating greater saphenous vein insufficiency. General anesthesia and peripheral nerve blocks with sedation have the risk of post-procedural delay in discharge and prolonged immobilization with the risk of deep vein thrombosis. The main pain experienced by patients during the procedure is during the laser ablation and the multiple needle punctures given along and around the great saphenous vein. The aim of our study was to evaluate the safety and efficacy of blocking the femoral nerve only under ultrasound-guidance without sedation, to reduce or prevent pain during injectable tumescent anesthesia in endovenous laser ablation of the greater saphenous vein...

Chronic obstructive pulmonary disease (COPD) has been associated with endothelial dysfunction and arterial stiffening, which are predictive of future cardiovascular events. While aerobic exercise improves vascular function in healthy individuals and those with chronic disease, it is unknown if aerobic exercise can positively modify the vasculature in COPD. We examined the effects of 8-weeks of periodised aerobic training on vascular structure and function and inflammation in 24 patients with COPD (age = 69 ± 7 yrs, FEV1 %pred = 68 ± 19%) and 20 matched controls (age = 64 ± 5 yrs, FEV1 %pred = 113 ± 16%) for comparison...
