Lymphangioma is a congenital malformation of lymphatic system and often involves the oral cavity. When lymphangioma is located on the mouth floor and enlarges, it can compress the airway and make intubation difficult. The GlideScope(®) video laryngoscope is sometimes used in routine intubation, but is most commonly used in difficult or failed intubation. We report a pediatric patient with a dif...

The most evolutionary advanced adaptations for plant parasitism by nematodes are the products of parasitism genes expressed in their esophageal gland cells and secreted through their stylet into host tissue to control the complex process of parasitism. Molecular analyses of nematode parasitism genes are revealing the complexity of the tools that enable the nematode to attack plants, and the res...

Three populations of Pratylenchus coffeae and two of P. brachyurus, each originating from a single female, were maintained on Citrus spp. or Solanum nigrum L. for several years under greenhouse conditions. Nematodes were extracted from roots, and adult female specimens were killed, fixed, and mounted in glycerine for microscopic study. Variables measured were distance between vulva and anus and...

A retropharyngeal mass may distort the airway anatomy and reduce the space available for manipulation of intubation devices. We encountered a patient with a cervical chordoma occupying the retropharyngeal space. Fiber-optic orotracheal intubation was attempted to secure the airway. Although the fiber-optic bronchoscope (FOB) was successfully placed into the trachea, the tracheal tube could not ...

During early stages of infestation by Russian wheat aphids (Diuraphis noxia [Mordvilko]; RWAs), barley (Hordeum vulgare L.) leaf cells collapsed and showed autofluorescence in the mesophyll and bundle sheath adjacent to the RWA stylet sheath. The response was visually similar to the hypersensitive cell death response, typical of resistance to microbial pathogens. Resistant barley produced signi...

One to two hundred nematodes from each of seven Xiphinema americanum-group populations were measured to determine the range of stylet and body lengths for juveniles and adults. First-stage juveniles were identified by the position of the replacement odontostyle (i.e., the tip of the replacement odontostyle overlapped the base of the odontophore). Nematodes were identified as second stage if the...

A simple implantable device was applied to the left middle cerebral artery of adult cats. One week later the artery was occluded acutely while the animals were conscious. Forced circling and tonic deviation of the head and neck toward the left were noted within seconds of occlusion. A right hemiparesis developed one to two minutes later. Cerebral angiography confirmed the presence of the middle...

Introduction The Shikani Optical Stylet (SOS; Clarus Medical, Minneapolis MN, USA) is another tool to facilitate tracheal intubation. It combines the benefits of a lightwand and a fiberoptic bronchoscope (FOB). It consists of a malleable stainless steel fiberoptic stylet in a preformed ‘J’, a removable ‘no focus’ eyepiece, and either a portable battery-operated light source handle or a traditio...

Awake fibreoptic intubation (AFI) is a standard method of airway management in a case of anticipated difficult intubation. It is usually performed using flexible fibroscopes. In this report, we describe the case of a 42 year-old female patient who suffered from congenital disease producing severe deformation of the head, face, neck and chest. In this case, the AFI procedure was performed succes...
