OBJECTIVE: To investigate patient pain perception from receiving MRI fusion guided prostate biopsy (FBx) in addition to transrectal ultrasound guided template biopsy (TBx) versus pain from standard TBx alone. MATERIALS AND METHODS: Patients undergoing FBx+TBx or TBx alone from April 2016 through February 2017 completed a validated pain survey after biopsy. Responses were graded from 0-10 (0: no pain/willing to return for repeat procedure; 10: excruciating pain/not willing to return for repeat procedure if necessary)...

The use of truncal nerve blocks has been described since 2001. Since then, there have been many studies trying to understand the ideal clinical scenarios for its use. Since 2001, the transversus abdominis plane block has evolved in many ways including from landmark based technique to ultrasound guided and more recently, into the quadratus lumborum (QL) block. Its anatomical placement, concentration of local anesthetic, volume of local anesthetic, and anatomic placement have all been raised as clinical questions...

BACKGROUND: Surgeon-performed periarticular injections and anesthesiologist-performed femoral nerve or adductor canal blocks with local anesthetic are in common use as part of multimodal pain management regimens for patients undergoing TKA. However, femoral nerve blocks risk causing quadriceps weakness and falls, and anesthesiologist-performed adductor canal blocks are costly in time and resources and may be unreliable. We investigated the feasibility of a surgeon-performed saphenous nerve ("adductor canal") block from within the knee at the time of TKA...

Interesting novel and somewhat perplexing physiologic and pathologic neuro-ocular findings have been documented in astronauts during and after long duration space flight (LDSF). These findings collectively have been termed the "space flight-associated neuro-ocular syndrome" (SANS). The National Aeronautics and Space Administration (NASA) in the United States has meticulously and prospectively documented the clinical, ultrasound, optical coherence tomography imaging, and radiographic findings of SANS including unilateral and bilateral optic disc edema, globe flattening, choroidal and retinal folds, hyperopic refractive error shifts, and nerve fiber layer infarcts (i...

Carpal Tunnel Syndrome (CTS) is the most common entrapment neuropathy, resulting in 500,000 carpal tunnel release (CTR) surgeries and a total cost of over 2 billion dollars annually in the United States.1,2 Although initially performed via a large (3-5 cm), palmar incision, CTR techniques have continually evolved to reduce recovery times and post-operative pain, and improve cosmesis and clinical outcomes.2,3 More recently, multiple authors have reported excellent results following ultrasound-guided carpal tunnel release (USCTR) using a variety techniques, and one prospective randomized trial reported faster recovery following USCTR compared to traditional mini-open CTR...

INTRODUCTION: Magnet therapy has been proposed as a treatment for neurologic conditions. This trial assessed the feasibility and efficacy of a magnet inserted into a wristband for carpal tunnel syndrome (CTS). METHODS: 22 patients with mild-to-moderate CTS were randomized to wear a high-dose or low-dose "sham" magnetic wristband for 6 weeks. The primary outcome was the symptom severity scale (SSS) of the Boston Carpal Tunnel Questionnaire. Secondary measures were nerve conduction studies (NCS), median nerve ultrasound, and compliance...

Background Carpal tunnel syndrome (CTS) is the most common peripheral compression neuropathy of the upper extremity. Recently, dynamic ultrasound (US) imaging has shown differences in median nerve mobility between the affected and unaffected sides in CTS. Purpose The present study was performed to compare the median nerve mobility between patients with CTS and healthy individuals, and to correlate median nerve mobility with the severity of CTS. Material and Methods A total of 101 patients (128 wrists) with CTS and 43 healthy individuals (70 wrists) were evaluated...

Chronic pain after surgery is a common and debilitating complication after many types of surgery. The cause and pathology behind is still mainly uncovered, though several risk factors have been proposed. One of the strongest risk factors for persistent postsurgical pain is the intensity of the acute pain response though the mechanisms involved remain unsettled...

Peripheral nerve blocks are becoming increasingly popular for perioperative use as anesthetics and analgesics in small animals. This prospective study was performed to investigate the duration of motor and sensory blockade following use of bupivacaine for ultrasound-guided femoral and sciatic nerve blocks in dogs and to measure the plasma concentrations of bupivacaine that result from these procedures. Six dogs were anesthetized twice using a randomized cross-over design. At the first anesthetic, dogs were assigned to receive either an ultrasound-guided femoral nerve block or sciatic nerve block with 0...

The recent epidemic of Zika virus (ZIKV) infection in Central and South America is one of the most serious global public health emergencies since the Ebola outbreak in West Africa. In Brazil, especially in the north, northeast, and southeast parts of the country, the ZIKV outbreak is a cause of concern for pregnant women because ZIKV intrauterine infection has been found to be associated with multiple brain malformations and microcephaly. In Brazil, the number of newborns with confirmed microcephaly per year recorded during the ZIKV outbreak, has been approximately 15 times greater than previously reported...

BACKGROUND: The treatment of acute pain in the emergency department is not always optimal. Peripheral nerve blocks using "blind" or nerve stimulator techniques have substantial disadvantages. Ultrasound-guided regional anesthesia may provide quick, safe, and effective pain relief in patients with proximal femoral fractures with severe pain. However, no evidence exists on emergency physician-performed ultrasound-guided regional anesthesia in these patients in Dutch emergency departments...

BACKGROUND: Non-invasive measurement of intracranial pressure (ICP) can be invaluable in the management of critically ill patients. Invasive measurement of ICP remains the "gold standard" and should be performed when clinical indications are met, but it is invasive and brings some risks. In this project, we aim to validate the non-invasive ICP (nICP) assessment models based on arterious and venous transcranial Doppler ultrasonography (TCD) and optic nerve sheath diameter (ONSD)...

Explantation of a left ventricular assist device (LVAD) may be challenging even in the most experienced hands. We aim to describe the technique for explantation of an LVAD together with the heart as applicable to all contemporary implantable mechanical assist devices. In order to ensure safe explantation, particular care must be taken at three distinct stages: at the time of LVAD implantation, at pre-transplant assessment and at the time of heart transplantation. The preparation for a safe explantation at LVAD implantation includes positioning the driveline and the outflow graft away from the back of the sternum to ensure protection from injury during re-entry into the chest...
