The headache which sometimes develops after a lumbar puncture has a dual interest, for not only is it important in the clinical management of the patient, but also it has stimulated enquiry into the causative mechanism of headache as a whole. Post-puncture headache has characteristic features. It may appear from a few hours to a few days after the puncture, and it is made worse by jugular compr...

Introduction: Evaluation of the cerebrospinal fluid (CSF) white blood cell (WBC) count and glucose and protein concentrations is used to assess the probability of the presence of central nervous system (CNS) infection. Although normal values are well established for CSF cell counts and protein and glucose contents in children and adults, this is not the case for neonates. The purpose of this st...

The present study explored a method to reduce X-ray exposure dose and avoid targeted puncture complications in percutaneous transforaminal endoscopic lumbar discectomy (PTELD). A total of 66 patients with lumbar disc herniation were divided into two groups for a controlled study. In the experimental group, 31 patients were subjected to PTELD using a novel targeted puncture technique with applic...

STUDY OBJECTIVE To assess the clinical use of ultrasonographic localization of the epidural space, and to evaluate the clinical efficacy of ultrasound diagnostics in obstetric anesthesia. DESIGN Randomized prospective study. SETTING University Clinic of Obstetrics and Gynecology. PATIENTS 300 parturients, 85 of whom had conventional delivery and 65 who underwent cesarean section. INTERV...

BACKGROUND Percutaneous vertebroplasty (PVP) has been demonstrated to be effective in the treatment of osteoporotic fracture. The bilateral pedicular approach is the most frequently used method. However, unilateral PVP is becoming increasingly more attractive for surgeons because of its numerous benefits, including lower radiation exposure, less tissue injury, and less bone cement leakage. The ...

BACKGROUND AND PURPOSE The relationship between reperfusion and clinical outcome is time-dependent, and the effect of reperfusion on outcome can vary on the basis of the extent of collateral flow. We aimed to identify the impact of time-to-reperfusion on outcome relative to baseline angiographic collateral grade in patients successfully treated with endovascular revascularization for acute larg...

We perform an analytic late time analysis for maximal slicing of the Reissner-Nordström black hole spacetime. In particular, we discuss the collapse of the lapse in terms of its late time behavior at the throat and at the event horizon for the even and the puncture lapse. In the latter case we also determine the value of the lapse at the puncture. Furthermore, in the limit of late times slice s...

Seventy-four patients with proved spontaneous subarachnoid haemorrhage were studied. Sixty-four underwent computed tomography and 55 underwent lumbar puncture. Seven cases deteriorated dramatically after lumbar puncture, six of these showing evidence of cerebral dislocation on further investigation. Four of the seven had not undergone computed tomography and three underwent computed tomography ...

T racheoesophageal puncture (TEP) is the preferred method for voice restoration following total laryngectomy. While several techniques for secondary puncture have been described, most require general anesthesia or intravenous sedation. Techniques for in-office, unsedated secondary TEP have been developed but are limited due to patient discomfort, inability to maintain direct visualization of th...
