The antero-posterior diameter of the lumbar dural sac does not predict sensory levels of spinal anesthesia for Cesarean delivery.
Abstract: The lumbosacral cerebrospinal fluid (CSF) volume, as assessed by magnetic resonance imaging, is a major determinant of the intrathecal spread of local anesthetics. Ultrasound imaging of the lumbar spine allows measurement of dural sac dimensions, which we...
Abnormal EEG lateralization in boys with autism
Abstract Objective: Functional brain abnormalities associated with autism in 3-8-year-old boys were studied with EEG recorded under controlled experimental condition of sustained visual attention and behavioral stillness. Methods: EEG was recorded in two independent...
The effect of oxygen therapy on brain damage and cerebral pO(2) in transient focal cerebral ischemia in the rat.
Abstract: We examined the effect of hyperbaric oxygen (HBO) and normobaric oxygen (NBO) on neurologic damage and brain oxygenation before and after focal cerebral ischemia in rats. A middle cerebral artery occlusion (MCAO)/reperfusion rat model was used. The rats were...
Autologous bone marrow transplantation and hyperbaric oxygen therapy for patients with thromboangiitis obliterans.
Abstract: Many patients suffering from severe ischemic limb disease inevitably experience amputation, despite intensive therapies. Sympathectomy and hyperbaric oxygen therapy are optional therapies for patients with peripheral circulation disorders. Recently, several...
The effect of oxygenation on the biological behaviour of tumours.
Malignant tumours often display hypoxic tissue areas where the oxygen tension is < 7 mm Hg. Studies in this field have proved that the hypoxic state boosts tumour progression and aggressive behaviour. In tissue culture experiments "in vitro" oxygenation was found to inhibit in itself the proliferation of cells of healthy tissues as well as benign and malignant tumours. It is a very important observation from oncotherapeutic point of view that in the presence of partial oxygen pressure < 2.5 mm Hg the radiosensitivity decreases (intrinsic radioresistance). Most of the anticancer drugs (cytostatics) are also ineffective in hypoxic tumours (chemoresistance).
Development of underwater and hyperbaric medicine in Malaysia.
Abstract: Underwater and Hyperbaric Medicine is a treatment modality gaining recognition in Malaysia. It uses the hyperbaric oxygen therapy (HBOT) approach where patients are placed in recompression chambers and subjected to oxygen therapy under pressure. In Malaysia...
Hyperbaric oxygen therapy mediates increased nitric oxide production associated with wound healing: a preliminary study.
Abstract: The objective of this preliminary study was to document general somatic and wound nitric oxide (NO) levels during and after hyperbaric oxygen therapy (HBOT). The study evaluated 6 chronic wound patients that responded favorably to HBOT treatment (20...
Bioengineered alternative tissues and hyperbaric oxygen in lower extremity wound healing.
Abstract: With the advent and clinical application of recombinant chemical and cellular mediators of wound healing and a better understanding of the importance of serial debridement, most foot wounds can be healed with little morbidity. Despite these advances, there...
Osteoradionecrosis of external auditory canal in nasopharyngeal carcinoma.
Abstract: Osteoradionecrosis (ORN) is one of the most serious complications of radiotherapy of nasopharyngeal carcinoma (NPC). ORN rarely occurs in the external auditory canal. This is a retrospective review of 11 NPC patients who had ORN in the external auditory...
