Background: The laryngeal mask airway (LMA) is a new form of airway which is introduced blindly into the hypo pharynx to form a seal around the larynx. Insertion of this LMA requires an adequate depth of anaesthesia, as the device is bulky and cannot be inserted unless jaw and pharynx are fully relaxed. The choice of the intravenous induction agent will influence the intubating conditions depen...

In this study, we describe the distribution of fibres that contain calcitonin gene-related peptide in normal bones and in bones that are remodeling after insertion of an implant. With routine histology and antibodies to calcitonin gene-related peptide, small neural and free-running fibres staining positively for calcitonin gene-related peptide were found in the periosteum, endosteum, and cortic...

When learning new words, do children use a speaker’s eye gaze because it reveals referential intent? We conducted two experiments that addressed this question. In Experiment 1, the experimenter left while two novel objects were placed where the child could see both, but the experimenter would be able to see only one. The experimenter returned, looked directly at the mutually visible object, and...

OBJECTIVES To assess the efficacy and safety of two versions of a blind placement temporary prostatic stent in the treatment of patients with benign prostatic obstruction. METHODS Two versions of a prostatic stent (blind placement stent 1 [BPS-1] and BPS-2) were blindly inserted in an outpatient setting under local anesthesia. An assessment of voiding function, symptom scores, and complicatio...

BACKGROUND Although most critically ill patients experience at least 1 blind insertion of a feeding tube during their stay in an intensive care unit, little is known about the types of health care personnel who perform these insertions or about methods used to determine proper positioning of the tubes. OBJECTIVES To describe results from a national survey of critical care nurses about feeding...

The standard setting for competitive analysis of online algorithms assumes that on-line algorithm knows the past (but not future) inputs, and can optimize its performance by \learning" from mistakes of the past. This framework cannot capture some of the real-life online decision-making, which takes place without full knowledge of past and present inputs. Instead, online algorithm only knows a f...

Organizations are increasingly outsourcing tasks once performed in-house to wider participants on the Internet by hosting online contests. In practice, two types of mechanisms are used to organize these contests: simultaneous (blind) and sequential (open). In a simultaneous contest, contestants submit their solutions independently without access to one another’s submissions, while in a sequenti...

The enlarged adenoid serves as a mechanical obstacle on the nasopharynx to intricate nasotracheal intubation. No matter what video or direct laryngoscopic techniques are applied, nasotracheal tube navigation from the nasal valve area through the nasal cavity to the nasopharynx is always blind; trauma is not uncommon. Here we report a case of unintended avulsed adenoids that plugged the tube tip...
