Arterial distensibility in patients with ruptured and unruptured intracranial aneurysms: is it a predisposing factor for rupture risk?
A risk factor assessment that reliably predicts whether patients are predisposed to intracranial aneurysm (IA) rupture has yet to be formulated. As such, the clinical management of unruptured IA remains unclear. Our aim was to determine whether impaired arterial distensibility and hypertrophic remodeling might be indicators of risk for IA rupture. ⋯ Patients with ruptured IAs demonstrated decreased arterial distensibility and increased intima-media thickness at the level of the carotid arteries. By measuring these parameters via ultrasound, it may be possible to predict whether patients with existing IAs might rupture and hemorrhage into the subarachnoid space.

Comparative Study Clinical Trial
Comparative evaluation of two different volumes of lidocaine in intravenous regional anesthesia.
This study was conducted to compare low concentration-high volume intravenous regional anesthesia (IVRA) method with local anesthetic method in upper extremity surgery in terms of efficiency and adverse effects. ⋯ IVRA technique applied with 2% concentration and volume of 12-15 mL lidocaine may be suggested as a safe option.

Spinal anesthesia with hyperbaric bupivacaine: a comparison of hypertensive and normotensive patients.
Hypotension is the most common problem with spinal anesthesia. This prospective study aimed to compare normotensive and hypertensive patients with respect to the hemodynamic effects of spinal anesthesia performed with hyperbaric bupivacaine. ⋯ There was no significant difference between normotensive and hypertensive patients in the incidences of hypotension caused by spinal anesthesia with 0.5% hyperbaric bupivacaine.

Pain catastrophizing, appraisals of pain control, styles of coping, and social support have been suggested to affect functioning in patients with low back pain. We investigated the relation of chronic pain coping strategies to psychological variables and clinical data, in patients treated surgically due to lumbar disc herniation and coexisting spondylotic changes. ⋯ Back pain characteristics, depressive mood, disability, and beliefs about personal control of pain are related to chronic LBP coping styles. Most of the variables related to advancement of degenerative changes were not associated with coping efforts.
