Crocetin is the main component of saffron and exhibits anti-oxidative and anti-inflammatory effects. Neuroinflammation and oxidative stress have been recognized to play a crucial role in the pathogenesis of neuropathic pain. We investigated the effect of crocetin in a mouse model with neuropathic pain induced by spared nerve injury (SNI). Crocetin was intrathecally perfused at various doses for up to 12 days starting 3 days before the surgery. Behavioral tests were performed to determine pain sensitivity. The concentrations of proinflammatory cytokines tumor necrosis factor (TNF-α) and interleukin-1β (IL-1β) were measured to assess neuroinflammation...

Dario Tumino, Francesco Frasca, Kate Newbold
Differentiated thyroid cancer (DTC) accounts for 95% of all thyroid cancers and is generally an indolent tumor, treated effectively with surgery, radioactive iodine, and thyroid-stimulating hormone suppressive therapy. However, 5-10% of patients have advanced disease, with aerodigestive tract invasion, distant metastases, or radioiodine refractory disease, with poor prognosis. This review focuses on the approaches for treating advanced DTC, including management of gross extra-thyroidal extension, recurrent loco-regional or distant metastatic disease, the role of external beam radiation therapy and systemic treatment...

Prashant Rao, Jack B Keenan, Taufiek K Rajab, Alice Ferng, Samuel Kim, Zain Khalpey
We describe the intraoperative non-invasive use of an infrared (IR) camera to monitor Del Nido cardioplegia delivery in patients undergoing cardiac surgery. Thermal pictures were taken pre- and post-cardioplegia and at timed points after arrest, and compared to readings from a transseptal temperature probe. There was good concordance between the transseptal probe and the IR camera temperature readings. This non-invasive technique, which assesses cardioplegic distribution, may help to determine when additional doses of Del Nido cardioplegia are required during periods of cardioplegic arrest...

HIFU (high intensity focused ultrasound) is a method in which high-frequency ultrasound is focused on a tissue in order to achieve a thermal effect and the subsequent percutaneously ablation, or tissue modulation. HIFU is non-invasive and results in an immediate tissue destruction effect corresponding to surgery, either percutaneously or through body cavities. HIFU can be utilized in the treatment of both benign and malignant tumors. In neurological diseases, focused HIFU can be used in the treatment of disorders of the basal ganglia...

Background: Neuropathic pain is a debilitating condition that severely affects the quality of life for those with this pain condition, and treatment for pain relief is greatly sought-after. Zerumbone (Zer), a sesquiterpene compound isolated from the rhizomes of a Southeast Asian ginger plant, Zingiber zerumbet (L.) Roscoe ex Smith. (Zingiberaceae), showed antinociceptive and antiinflammatory properties when previously tested on models of nociception and inflammation. Objective: This study investigated the effects of prophylactic administration of zerumbone on allodynia and hyperalgesia in a mouse model of chronic constriction injury (CCI)-induced neuropathic pain...

Persistent inflammation, mediated in part by increases in cytokines, is a hallmark of traumatlc brain injury (TBI). Minocycline has been shown to inhibit post-TBI neuroinflammation in male rats and mice, but has not been tested in females. Here we studied sex differences in thermal, stress and inflammatory responses to TBI and minocycline. Female rats were ovariectomized under isoflurane anesthesia at 33-36 days of age. At 45-55 days of age male and female rats were implanted intraperitoneally (i.p.) with calibrated transmitters for monitoring body temperature...

The external branch of the superior laryngeal nerve (EBSLN) innervates the cricothyroid muscle (CTM) to promote lengthening and thinning of the vocal fold, thus increasing voice pitch. The close relation with the superior thyroid vessels (STV) puts the EBSLN in risk every time the superior pole of the thyroid is dissected. It travels downward to innervate the CTM, lateral to the thyroid cartilage and to the inferior pharyngeal constrictor muscle (IPCM), being eventually covered by this muscle fibers as it approaches its entry point...

BACKGROUND: Perioperative fentanyl has been reported to induce hyperalgesia and increase postoperative pain. In this study, we tried to investigate behavioral hyperalgesia, the expression of proinflammatory cytokines, such as interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α), and the activation of microglia in the spinal cord and dorsal root ganglion (DRG) in a rat model of surgical plantar incision with or without perioperative fentanyl. METHODS: Four groups of rats (n = 32 for each group) were subcutaneously injected with fentanyl at 60 μg/kg or normal saline for 4 times with 15-minute intervals...

BACKGROUND: During the past decades' sepsis has become the major cause of death in severely burned patients. Despite the importance of burn sepsis, its diagnosis, let alone its prediction, is difficult if not impossible. Recently, we have demonstrated burn patients have increased NLRP3 inflammasome activation in white adipose tissue. We aimed to delineate a unique immune profile that can be used to identify septic outcomes in severely burned patients. METHODS: Adult burn patients (n = 37) admitted to our burn center between June 2013-2015 were enrolled in this study...

The electrosurgical electrode currently stands out as one of the most commonly used tools in minimally invasive surgery. In order to facilitate tissue cutting and accelerate wound healing, tissue adhesion to the electrosurgical electrode is considered as an extremely urgent problem to be solved. In this paper, a novel ultrasonic vibration assisted (UV-A) electrosurgical electrode is firstly proposed to overcome the problem of tissue sticking. The anti-adhesion effects were evaluated by measuring the adhesion force and the weight of tissue adhesion using the electrosurgical electrode with and without UV-A comparatively...

Stereotactic laser ablation of mesial temporal structures is a promising new surgical intervention for patients with mesial temporal lobe epilepsy (MTLE). Since this procedure was first used to treat MTLE in 2010, the literature contains reports of 37 patients that underwent MR-guided stereotactic laser amygdalohippocampotomy (SLAH) using Laser Interstitial Thermal Therapy (LITT) with at least 1year of follow-up. This early body of data suggests that SLAH is a safe and effective treatment for MTLE in properly selected patients...

Among other autonomic dysfunctions complicating acute spinal cord injury, deep hypothermia is rare but may induce serious cardiovascular complications. There are few pharmacological options to influence hypothermia. A 66-year-old woman was transferred to the intensive care unit (ICU) for serious cardiac arrhythmias (atrial fibrillation and asystole) in the context of a deep hypothermia (axillary temperature below 32°C). She had been admitted to the hospital two months before for an acute L4-L5 infectious spondylodiscitis without any initial neurological deficit...
