BACKGROUND Chronic postsurgical pain (CPSP) is an important clinical problem. Prospective studies of the incidence, characteristics and risk factors of CPSP are needed. OBJECTIVES The objective of this study is to evaluate the incidence and risk factors of CPSP. DESIGN A multicentre, prospective, observational trial. SETTING Twenty-one hospitals in 11(More)
AIMS The purpose of this study was to evaluate excision and open granulation versus excision and primary closure as treatments for pilonidal sinus. SUBJECTS AND METHODS We evaluated a group of 141 patients operated on for a pilonidal sinus between 1991 and 1995. Ninety patients were treated by excision and open granulation, 34 patients by excision and(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)
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)
Neuromodulation techniques modify the activity of the central or peripheral nervous system. Spinal cord stimulation is a reversible and minimally invasive treatment whose efficacy and cost effectiveness are recognized for the treatment of chronic neuropathic pain or ischemic pain. Spinal cord stimulation is not the option of last resort and should be(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   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)
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)
OBJECTIVE We compared the analgesia and the quality of life of a constant daily dose of intrathecal drug administered at different flow rates in patients treated for chronic pain. We postulate that the quality of the analgesia, at the same daily dose, will show an infusion rate dependent pattern with decreased pain at higher flow rates. PATIENTS Twenty(More)
Coil embolization of the internal iliac artery (IIA) for proper endovascular treatment of aortoiliac aneurysms is a procedure with an acceptable morbidity rate consisting of buttock claudication in 12% to 55% and erectile dysfunction in 1% to 13%. Atheroembolic complications in this context are not yet reported. We present a case with gangrene of the(More)
