Good General Condition

A 42-year-old male presented with fever and symptoms of impending upper airway obstruction on the day of presentation. He required immediate intubation due to swollen epiglottis. The condition responded to antibiotic and steroids, and he was able to be extubated after 3 days. Two days later, however, the epiglottis started to swell up again, this time with pus discharge. Emergency exploration and drainage of the epiglottic abscess were executed, and the patient was kept intubated for a few days afterwards for the swollen epiglottis to reduce in size. Daily flexible laryngoscopy was commenced to monitor the disease status. After completing the antibiotic therapy the patient was discharged in good general condition.

Hemophilus Influenzae

Epiglottitis, along with other infectious croup syndromes (laryngotracheitis and spasmodic croup), are illnesses which cause acute upper airway obstruction. They are discussed in terms of etiology, symptoms, diagnosis and treatment. Cellulitis and the role of Hemophilus influenzae and antibiotic therapy are also described.

AbstractCongenital laryngeal cysts are a rare cause of neonatal upper airway obstruction which may lead to serious morbidity and mortality if diagnosis and treatment are delayed. We reviewed our experience with nine patients over a six-year period. The annual incidence of this condition was 1.82 per 100,000 live births. The diagnosis can be confirmed safely by flexible laryngoscopy before definitive surgery is contemplated. Contrary to other studies, we found that endoscopic removal of cysts can achieve an effective cure without recurrence. Endoscopic deroofing is as effective as endoscopic excision but is technically simpler and thus is recommended as the treatment of choice.

AbstractElectrical signals from the peripheral nervous system have the potential to provide the necessary motor, sensory or autonomic information for implementing closed-loop control of neuroprosthetic or neuromodulatory systems. However, developing methods to recover information encoded in these signals is a significant challenge. Our goal was to test the feasibility of measuring physiologically generated nerve action potentials that can be classified as sensory or motor signals. A tetrapolar recording nerve cuff electrode was used to measure vagal nerve (VN) activity in a rodent model of upper airway obstruction. The effect of upper airway occlusions on VN activity related to respiration (RnP) was calculated and compared for 4 different cases: (1) intact VN, (2) VN transection only proximal to recording electrode, (3) VN transection only distal to the recording electrode, and (4) transection of VN proximal and distal to electrode. We employed a Support Vector Machine (SVM) model with Gaussian Kernel to learn a model capable of classifying efferent and afferent waveforms obtained from the tetrapolar electrode. In vivo results showed that the RnP values decreased significantly during obstruction by 91.7% ± 3.1%, and 78.2% ± 3.4% for cases of intact VN or proximal transection, respectively. In contrast, there were no significant changes for cases of VN transection at the distal end or both ends of the electrode. The SVM model yielded an 85.8% accuracy in distinguishing motor and sensory signals. The feasibility of measuring low-noise directionally-sensitive neural activity using a tetrapolar nerve cuff electrode along with the use of an SVM classifier was shown. Future experimental work in chronic implant studies is needed to support clinical translatability.
