one studies the $hx$-hypergroups, corresponding to the chinese hypergroups associated with the direct products of some ${bf z}/n {bf z},$ calculating their fuzzy grades.

in this study we have described our varicocele cases in terms of associated symptoms/signs. in addition, we have tested the correlation between semen parameters and varicocele grades and compared the relative frequencies of associated symptoms/signs in different varicocele grades. 1 19 referred cases of varicocele were categorized based on clinical criteria into 3 grades by one examiner. the re...

Morbid obesity is associated with a more rapid decrease in oxygen saturation during apnea following induction of anesthesia, compared to patients who have normal weight1. This is particularly hazardous as morbid obesity, complicated by obstructive sleep apnea, may be associated with an increased risk of difficult tracheal intubation and difficult face mask ventilation2. These morbidly obese pat...

BACKGROUND The major drawback of Cormack Lehane classification for airway assessment is its dependence on invasive direct laryngoscopy and hence it is inapplicable for pre-anesthetic assessment of airway in patients with no prior history of tracheal intubation. STUDY OBJECTIVES The purpose of the study was to compare and correlate the ultrasound view of the airway and the Cormack Lehane class...

Awake intubation with fiberoptic bronchoscopy (FOB) is a popular technique in patients with difficult intubation criteria. Preservation of spontaneous respiration by nasotracheal intubation with FOB accompanied by sedation was performed in a case assessed as difficult intubation due to a high Mallampati score at preoperative evaluation and the presence of a mass extending to the oral cavity. Fo...
