INTRODUCTION Spinal cord stimulation is a recognized treatment of chronic neuropathic and vascular pain. Recent data suggest that the use of very high-frequency (HF) stimulation modes does produce analgesia without paresthesia. AIM OF THE STUDY To compare the efficacy of HF stimulation (HF spinal cord stimulation [HFSCS]) and sham stimulation on the(More)
OBJECTIVES This study evaluated efficacy and safety of bolus doses of ziconotide (Prialt®, Eisai Limited, Hertfordshire, UK) to assess the option of continuous administration of this drug via an implanted intrathecal drug delivery system. MATERIALS AND METHODS Twenty adults with severe chronic pain who were under consideration for intrathecal (IT) therapy(More)
BACKGROUND Modern theories define chronic pain as a multidimensional experience - the result of complex interplay between physiological and psychological factors with significant impact on patients' physical, emotional and social functioning. The development of reliable assessment tools capable of capturing the multidimensional impact of chronic pain has(More)
Difficult tracheal intubation assessment is an important research topic in anesthesia as failed intubations are important causes of mortality in anesthetic practice. The modified Mallampati score is widely used, alone or in conjunction with other criteria, to predict the difficulty of intubation. This work presents an automatic method to assess the modified(More)
The coronary arteries supply the heart muscle (myocardium) with oxygen and nutrients. According to current scientific views, low-grade inflammation causes lipid deposits in the artery wall, which may create plaques. This condition, atherosclerosis, occurs predominantly in larger arteries, including coronary arteries. The subsequent narrowing of the artery(More)
INTRODUCTION Pain treatment is best performed when a patient-centric, safety-based philosophy is used to determine an algorithmic process to guide care. Since 2007, the International Neuromodulation Society has organized a group of experts to evaluate evidence and create a Polyanalgesic Consensus Conference (PACC) to guide practice. METHODS The current(More)
BACKGROUND   Complications associated with intrathecal pumps may be linked to the surgical procedure, the implanted device, or the medication itself. CASE REPORTS   Three patients treated chronically with intrathecal clonidine presented with clonidine overdose due to inadvertent extravasation during the refilling procedure. All patients experienced loss(More)
GOAL Difficult tracheal intubation is a major cause of anesthesia-related injuries with potential life threatening complications. Detection and anticipation of difficult airway in the preoperative period is, thus, crucial for the patients' safety. We propose an automatic face-analysis approach to detect morphological traits related to difficult intubation(More)
INTRODUCTION Intrathecal (IT) pump failures usually result in decreased drug administration and symptom reoccurrence with or without withdrawal syndrome. We report a case of a leaking silicone septum associated to a systemic drug overdose. CASE REPORT An 84-year-old patient treated with IT clonidine for chronic back pain presented with a state of(More)
Chronic pain, defined as persistent or recurrent pain lasting longer than 3 months, is a frequent condition affecting an important percent of population worldwide. Pain chronicity can be caused by many different factors and is a frequent component of many neurological disorders. An important aspect for clinical assessment and design of effective treatment(More)
