PURPOSE To develop an active MR-tracking system to guide placement of metallic devices for radiation therapy. METHODS An actively tracked metallic stylet for brachytherapy was constructed by adding printed-circuit micro-coils to a commercial stylet. The coil design was optimized by electromagnetic simulation, and has a radio-frequency lobe pattern extending ∼5 mm beyond the strong B0 inhomoge...

Case Report A 71-year-old man with ischemic cardiomyopathy and prior coronary artery bypass grafting surgery with a dual-chamber implantable cardioverter-defibrillator (ICD) placed 4 years earlier for a history of ventricular tachycardia was referred for lead extraction because of recurrent fever, vegetations on his atrial lead, and Kocuria varians bacteremia. He had a Guidant 4470 right atrial...

BACKGROUND Optiscope™ is a newly developed video stylet device. This study evaluated and compared the hemodynamic changes observed after endotracheal intubation with video stylet and after conventional laryngoscopic endotracheal intubation. METHODS Fifty-eight adult patients with American Society of Anesthesiologists (ASA) physical status class 1 or 2, undergoing general anesthesia, were rand...

BACKGROUND AND OBJECTIVES Approaching the airways with a laryngoscope can cause different types of injuries. The objective of the present study was to determine whether lighted stylet tracheal intubation can be a less traumatic alternative for patients when compared to direct laryngoscopy. METHODS Ninety-eight patients between 16 and 88 years and physical status ASA I and II participated in t...

By utilising targeted microprobe technology, the analysis of elements incorporated within the hard bio-mineralised structures of marine organisms has provided unique insights into the population biology of many species. As hard structures grow, elements from surrounding waters are incorporated effectively providing a natural ‘tag’ that is often unique to the animal’s particular location or habi...

We present a new intubation technique using an oral preformed tracheal tube passed through a laryngeal mask. Six patients (neonate to six months old) with craniofacial malformations of head and neck and scheduled for reconstructive plastic surgery are the basis of this report. An inhalation induction with increasing doses of halothane in oxygen while maintaining spontaneous ventilation was perf...

readily be achieved with the inverted insertion (i.e., with the concave surface facing backward) of a polyvinyl chloride endotracheal tube.2 They attributed their success, in part, to the more anatomic direction of the tube on emergence from the Fastrach laryngeal mask airway with the inverted tube insertion technique. A similar “hang up” is often seen during tracheal intubation using the Bulla...

Meloidogyne morocciensis n. sp. is described from specimens parasitic on peach rootstock from Morocco. This species exhibits a combination of morphological characters similar to M. arenaria, M. incognita, and M. javanica. The perineal pattern of females is oval to squarish with a moderately high to high dorsal arch, and widely spaced, smooth striae; lateral lines are absent. The stylet, 16.5 mu...

A 55-year-old female patient with earlier diagnosis of cardiac cirrhosis and mitral valve implantation was admitted with complaints of weakness and dizziness. She had undergone VVIR pacemaker implantation 9 years earlier due to low ventricular rate atrial fibrillation and had generator replacement procedure 3 months previously. Electrocardiogram indicated pacemaker dysfunction due to failure to...

Systematic contributions to Heteroderidae include description of Cactodera eremica n. sp., an emended diagnosis of Sarisodera Wouts and Sher, 1971, and proposal of a new genus and new combination, Afenestrata africana (synonym Sarisodera africana Luc et al., 1973). Cactodera eremica, from the roots of shadscale in Utah, most closely resembles Cactodera thornei (Golden and Raski, 1977) but diffe...
