Head shape and stylet morphology of second-stage juveniles of one population each of M. incognita, M. javanica, M. arenaria, and M. hapla were compared by light microscopy. Excised stylets of each species were also compared by scanning electron microscopy (SEM). Differences in head morphology were observed only between M. hapla and the other three species. In SEM, differences in stylet size, sh...

Fibreoptic and video technologies are widely used for airway management. Fibreoptics have been used in most airway intubation devices, including rigid laryngoscopes and in the tracheal tube wall itself. 22 Optical stylets, which incorporate ̄exible ®breoptic imaging elements in an intubation stylet, have now also become available. More than 10 new optical stylet devices have been introduced sinc...

I read the recent article by Garg,(1) in which the author described the use of a spinal needle stylet to replace a faulty intravenous cannula. The technique is useful; however, there are some concerns. We have tried the stylet of a 26-G spinal needle for the exchange of a 24-G cannula in ten paediatric patients and have the following observations to make. The exchange was successful in only one...

Introduction: Rapid sequence induction (RSI) is usually indicated during emergency surgical procedure in the presence of full stomach and other conditions with an increased risk of aspiration. The use of succinylcholine has been the gold standard for RSI because of its rapid onset and short duration of action in spite of its adverse effects and contraindications in many conditions. Because of t...

Meloidogyne microcephala n. sp. is described and illustrated from specimens obtained from tobacco (Nicotiana tabacum L.) in Thailand. The female perineal pattern usually has a low dorsal arch, coarse striae, and a series of small cuticular flaps around the tail terminus. The stylet of the female is 14.4 mum long, with large, square to rectangular stylet knobs, The distinctive male head region i...

In this paper, we describe two new species of Syndesmis living in Pseudechinus magellanicus in the Southwest Atlantic Ocean. The new species have a long stylet in the male reproductive system, which is different from that of the known species of the genus. Specimens of Syndesmis selknami n. sp. have a ∼220-μm-long stylet (∼1/3 of the body length, 0.69 mm). This ratio is unique because only four...

Background: Perforation of intra-abdominal organs such as the bowel and urinary bladder is one of the most serious complications related to peritoneal dialysis catheter (PDC) insertion procedures. Such a risk increases in patients with a history of prior abdominal surgery or irradiation. The “alpha-replacer” is a unique wire that is usually soft, but becomes harder if coiled in the hand. Applic...

The leading cause of anesthesia-related injury is the inability to intubate the trachea and secure the airway.1 Improvements in video and optical laryngoscopy have allowed to obtain an indirect view of the glottis in a more simple way but sometimes this advantage occurs together with a difficult or impossible endotracheal tube (ETT) insertion.2 This is because indirect techniques do not require...
