We demonstrate a new method for extracting high-level scene information from the type of data available from simultaneous localisation and mapping systems. We model the scene with a collection of primitives (such as bounded planes), and make explicit use of both visible and occluded points in order to refine the model. Since our formulation allows for different kinds of primitives and an arbitr...

Of 2,272 deliveries between 1 October, 1967 and 31 December, 1968 290 were induced by simultaneous intravenous Syntocinon (synthetic oxytocin) at amniotomy. The hazards of induction of labour are greatly reduced when this method is used routinely. Only 4 of the 13 caesarean sections were thought to be due to failure of method. Within 12 hours 221 patients were delivered, and this short inductio...

background: musculoskeletal pain is a major clinical problem, but researchers lack viable animal models to study this phenomenon. however, formalin injections are widely used to produce tonic and neurogenic nociceptive responses in rodents. rodents can present a potential animal model for pain. objectives: to develop a muscle pain model with intramuscular injection of formalin in rats. material...

context lumbar central spinal stenosis is common and often results in chronic persistent pain and disability, which can lead to multiple interventions. after the failure of conservative treatment, either surgical or nonsurgical modalities such as epidural injections are contemplated in the management of lumbar spinal stenosis. evidence acquisition recent randomized trials, systematic reviews an...

conclusions we conclude that intraperitoneal hydrocortisone instillation caused leukocytosis and is thus suggested not to be used in immune-compromised patients. results the study was completed by 120 patients. patients who received intraperitoneal hydrocortisone and hydrocortisone plus bupivacaine had higher white blood cell (wbc) count (p < 0.0001). the patients were similar with respect to d...

results first needle placement without imaging resulted in blood return in 1/199 participants and positive epidurography in 179/199 (90%). minimal needle repositioning resulted in a positive epidurogram in the remaining 19 attempts. no intravascular injection patterns were observed. conclusions this compares favorably to published success rates of fluoroscopically-guided technique and was well ...

conclusions obtained results demonstrate significant differences between intraneural and perineural injection pressures in the median, ulnar, and radial nerves. intraneural injection pressures show low specificity but high sensitivity suggesting that pressure monitoring might be a valuable tool in improving the safety and efficacy of peripheral nerve blockade in regional anesthesia. peripheral ...

introduction: in order to study the alterations of beta 1 and 2 integrins mrna level in rat lumbar spinal cord following the induction of chronic pain and its effect on the development of tolerance to morphine analgesia, we examined the level of expression of these genes in the presence of chronic pain, which is an inhibitor of morphine tolerance. we used induction of chronic pain alone and in ...
