This study involved 154 anesthetized patients requiring endotracheal intubation, in whom the epiglottis was visible but not lifted, which restricted the view of the glottis. A simple stylet was used to lift the epiglottis, thus improving the view of the glottis with the Glide Scope®, allowing tracheal tubes to be inserted into the patients. The stylet easily resolved the difficulty of lifting t...

Discocriconemella inaratus n. sp. from Iowa prairies is characterized by a single offset disk-shaped head annule which is often discontinuous, a sigmoid vagina, a stylet length of 51-61 mum, and 77-100 smooth body annules. Criconemoides inusitatus n. sp. from Iowa woodlands is characterized by two offset head annules, a "closed" vulva, a straight vagina, no overlapping anterior vulva lip, a sty...

This report describes perforation of the aorta related to the implantation of an active-fixation atrial pacing lead, a previously undocumented complication of pacemaker implantation. The complication was related to excessive tissue penetration by the screw at the tip of the lead or perforation of the lead body by the positioning stylet during manipulation whereupon the stylet traversed the atri...

Completion of uterine curettage may be challenging following uterine perforation even under sonographic and laparoscopic monitoring. This report illustrates the use of a flexible intubating stylet as a guide to place the suction curette into the uterine cavity when sonography and laparoscopy alone are not successful. Use of a malleable instrument such as an intubating stylet as a guide should b...

A preterm with gestational age of 24 weeks was intubated at day of life 16. The intubation was done in a routine manner with the use of a stylet. It took a significant effort from the clinician to pull the stylet out after intubation. After intubation the respiratory status of the neonate deteriorated requiring significantly greater support. When ventilating and oxygenating the infant was getti...

A morphological comparison of seven hypotriploid populations of Meloidogyne arenaria was made to clarify their taxonomic status, using light and scanning electron microscopy. All populations differed from each other and from the typical triploid M. arenaria by certain features. Differences were not regarded as sufficient to justify recognition of the variants as distinct species. Morphological ...

Meloidogyne californiensis n. sp. is described and illustrated from bulrush Scirpus robustus in California. LM and SEM studies revealed that this species differs from other known species in the genus Meloidogyne especially by the prominent posterior cuticular protuberances in the female, the distinct shape of the perineal pattern which is marked by one prominent stria in the perineum, indistinc...

Ten populations of Xiphinema americanum-group nematodes were reared from individual females to evaluate inter- and intraspecific variation under identical host and environmental conditions. Data indicated that morphometric variability of X. americanum was the result of genetic variation rather than phenotypic plasticity and that genetic heterogeneity was greater than previously thought. Morphom...

A new species of Discocriconemella and the male of Discocriconemella degrissei are described from Minas Gerais state of Brazil. Discocriconemella mineira n. sp. differs from D. discolabia by having a longer stylet (61-71 vs. 35-47 mum) and fewer body annuli (78-88 vs. 155-174), and from D. inarata by the longer stylet (61-71 vs. 51-61 'm) and shorter body length (253-342 vs. 354-486 mum). It di...
