BACKGROUND AND PURPOSE Tools for noninvasive mapping of hemodynamic function including cerebrovascular reactivity are emerging and may become clinically useful to predict tissue at hemodynamic risk. One such technique assesses blood oxygen level-dependent (BOLD) MR imaging contrast in response to hypercapnia, but the reliability of its quantification is(More)
OBJECTIVES The neuromuscular transmission failure in acute organophosphate (OP) poisoning occurs because of the irreversible inactivation of the enzyme acetylcholinesterase located in the neuromuscular junction, and is distinguished neuroelectrophysiologically by single electrical stimulus-induced repetitive responses and either a decremental or a(More)
Genu varum in the achondroplastic patient has a complex and multifactorial aetiology. There is little mention in the literature of the role of fibular overgrowth. Using the ratio of fibular to tibial length as a measurement of possible fibular overgrowth, we have related it to the development of genu varum. Full-length standing anteroposterior radiographs(More)
CONTEXT ProSeal laryngeal mask airway (PLMA) efficacy in pediatric anesthesia. AIMS The aim of this study was to compare PLMA size 2 and 2½ in anesthetized paralyzed pediatric patients weighing 20-30 kg undergoing elective surgery. SETTINGS AND DESIGN A prospective randomized study was conducted in a tertiary care teaching hospital. MATERIALS AND(More)
Tetanus is an acute often fatal disease produced by gram positive obligate anaerobic bacterium Clostridium tetani. Tetanolysin damages local tissue and provides optimal conditions for bacterial multiplication. It is therefore important to perform a wide debridement of any wound suspected of being a portal of entry for the bacteria. Little evidence exists to(More)
OBJECTIVE Sevoflurane and propofol are considered to be the agents of choice in surgeries of short duration due to their better recovery profile and few post-operative complications. This study was designed to compare the early recovery profile of sevoflurane and propofol anesthesia in patients undergoing open cholecystectomy. MATERIALS AND METHODS A(More)
Six patients with acute organophosphate pesticide poisoning in whom electrodiagnostic studies influenced or supported specific decisions in management are described. One patient was admitted to hospital with a diagnosis of acute alcoholic intoxication. Electrodiagnostic studies revealed single stimulus induced repetitive responses and decrement-increment(More)
