Tocilizumab as first treatment option in optic neuropathy secondary to Graves' orbitopathy.

2018

Dysthyroid optic neuropathy (DON) is one of the complications that can affect Graves' orbitopathy (GO) patients. Its prevalence is estimated at less than 5%. It is usually treated with intravenous steroids, radiotherapy or orbital decompression. Tocilizumab has been proposed as a treatment option in cases of GO refractory to steroid treatment, with good clinical results. Our aim is to report the case of a patient with optic neuropathy secondary to GO treated with tocilizumab as primary treatment option.

Emerging Therapeutic Strategies for Traumatic Spinal Cord Injury

2020

Spinal cord injury (SCI) is a debilitating neurologic condition with tremendous socioeconomic impact on affected individuals and the health care system. The treatment of SCI principally includes surgical treatment and marginal pharmacologic and rehabilitation therapies targeting secondary events with minor clinical improvements. This unsuccessful result mainly reflects the complexity of SCI pathophysiology and the diverse biochemical and physiologic changes that occur in the injured spinal cord. Once the nervous system is injured, cascades of cellular and molecular events are triggered at varying times. Although the cascade of tissue reactions and cell injury develops over a period of days …

Sinusitis in Thyroid Associated Ophthalmopathy

1993

In 19 patients with thyroid associated ophthalmopathy undergoing orbital decompression, histologic examination of paranasal sinus mucosa revealed moderate to severe inflammatory alterations in all patients. Only 2/19 patients had a history of chronic sinusitis. In 4/19 patients, mucosal abnormalities of the paranasal sinuses were found on preoperative computed tomography CT scans. Postoperatively, 10/19 patients developed purulent sinusitis. It is suggested that patients suffering from thyroid associated ophthalmopathy have an increased incidence of histologically detectable inflammatory changes of paranasal sinus mucosa. Because of preexisting mucosal inflammation, these patients are pron…

Characteristics and treatment of Multiple Sclerosis-related trigeminal neuralgia: An Italian multi-centre study

2019

Abstract Background The prevalence of trigeminal neuralgia (TN) in Multiple Sclerosis (MS) patients is higher than in the general population and its management can be particularly challenging. Our aim is to describe the characteristics, treatment and prognostic factors of MS-related TN in a retrospective multicentre study. Methods Neurologists members of the RIREMS group (Rising Researchers in MS) enrolled MS patients with a TN diagnosis and filled out a spreadsheet comprising their clinical data. Results Population consisted of 298 patients. First-choice preventive treatments were carbamazepine and oxcarbazepine. A surgical procedure was performed in 81 (30%) patients, most commonly gamma …

Branch ligatures and blood aspiration for post-traumatic superficial temporal artery pseudoaneurysm: surgical technique

2014

The aim of this study is to report a new minimally invasive technique of superficial temporal artery (STA) pseudoaneurysm treatment. Several surgical options have been employed to treat STA pseudoaneurysms. To address this rare condition, the employed techniques are ligation and excision of the aneurysm, endovascular coil embolization or percutaneous ultrasound-guided thrombin injection. Between techniques no significant differences are reported in terms of outcomes. The decision to adopt a technique depends on STA pseudoaneurysm morphology and surgeon preference. In the present report, STA pseudoaneurysm afferent and efferent branches were identified by ultrasound in a 92-year-old female. …

Sensitivity and specificity of MRA in the diagnosis of neurovascular compression in patients with trigeminal neuralgia

1998

The published rates of operatively confirmed neurovascular compression as the cause for trigeminal neuralgia range from 10 % to nearly 100 %. High-definition magnetic resonance angiography (MRA) was performed in 27 consecutive patients (in 6 cases with 3D reconstructions) to show neurovascular compression preoperatively. The MRA findings were compared with the relationship between the Vth nerve and the surrounding vessels at surgery. In 23 patients MRA showed present neurovascular compression in accordance with surgical findings (18/27 in complete accordance of type and side of vessel, site and direction of compression). One woman had no neurovascular compression either on MRA or intraopera…

Surgical Treatment for Traumatic Brain Injury: Is It Time for Reappraisal?

2015

Traumatic brain injury (TBI) is a major cause of morbidity and mortality in the United States. It is estimated that each year, on average, TBIs associated with 1.1 million visits to the emergency department, 235,000 hospitalizations, and 50,000 deaths.

Generation of CO2-rich melts during basalt magma ascent and degassing

2013

International audience; To test mechanisms of basaltic ma gma degassing, continuous decompressions of volatile-bearing (2.7-3.8 wt% H2O, 600-1300 ppm CO2) Stromboli melts were performed from 250-200 to 50-25 MPa at 1180-1140°C. Ascent rates were varied from 0.25 to ~ 1.5 m/s. Glasses after decompression show a wide range of textures, from totally bubble-free to bubble-rich, the latter with bubble number densities from 104 to 106/cm3, similar to Stromboli pumices. Vesicularities range from 0 to ~ 20 vol%. Final melt H2O concentrations are homogeneous and always close to solubilities. In contrast, the rate of vesiculation controls the final melt CO2 concentration. High vesicularity charges ha…
