Etzer Augustin, Michael Karsy, Jim Bryan, Jian Guan, Richard H Schmidt
Tension pneumocephalus is a rare but dangerous complication of craniotomy, sinus surgery, and traumatic cranial injury. Compared with simple pneumocephalus, which often resolves spontaneously over the course of a few days, tension pneumocephalus tends to increase with ongoing cerebrospinal fluid leak and requires immediate neurosurgical treatment to prevent cerebral herniation. Air transport of patients with tension pneumocephalus for neurosurgical care entails a risk of neurologic worsening because of changes in ambient air pressure with altitude and cabin pressurization...

BACKGROUND: Difficult-airway prediction tools help identify optimal airway techniques, but were derived in elective surgery patients and may not be applicable to emergency rapid sequence intubation (RSI). The HEAVEN criteria (Hypoxemia, Extremes of size, Anatomic abnormalities, Vomit/blood/fluid, Exsanguination, Neck mobility issues) may be more relevant to emergency RSI patients. OBJECTIVE: To validate the HEAVEN criteria for difficult-airway prediction in emergency RSI using a large air medical cohort...

BACKGROUND: Hygienic and microbiologically sterile air quality is essential for successful guideline-based work in operating theatres. To ensure clean air and to reduce contamination during surgery, ventilation systems are indispensable. Ventilation systems should be especially designed to keep the number of particles and germs under statutory limits. Therefore, they must be operated to recognised standards of good practice and be periodically inspected and maintained. The objective of this study was to prove, through the analysis of observation outside surgery time (rest condition), the effects of ventilation systems on air quality in a medical facility...

Mask ventilation and coughing during oro-tracheal suctioning produce aerosols that enhance nosocomial transmission of respiratory infections. We examined the extent of exhaled air dispersion from a human-patient-simulator during mask ventilation by different groups of healthcare workers and coughing bouts. The simulator was programmed to mimic varying severity of lung injury. Exhaled airflow was marked with tiny smoke particles, and highlighted by laser light-sheet. We determined the normalized exhaled air concentration in the leakage jet plume from the light scattered by smoke particles...

Background/aim: The incidence of adenoid hypertrophy is 2%-3% in children. Adenoidectomy is a commonly performed procedure in children that may cause complications such as early or late bleeding (4%-5%), recurrence of adenoid tissue (10%-20%), and postoperative respiratory problems (27%). Therefore, medical therapy alternatives to adenoidectomy are important and must be tried before surgery. In this study, we investigated the efficacy of mometasone furoate, montelukast, and a combination of these drugs in pediatric patients with adenoid hypertrophy who were scheduled for reduction with medical therapy after not being recommended for surgery...

Dry eye is a substantial problem in a large number of human and canine patients. Numerous laboratory models for tear deficiency exist using genetically predisposed rodent models, animals treated with topical anti-muscarinics, or those kept in environments with increased air flow to produce the ocular surface changes seen in human patients. Canine keratoconjunctivitis sicca, seen in many thousands of dogs kept as companion animals, can provide a valuable spontaneous model for testing tear replacement medications that might better model disease in human patients, existing as it does in an outbred population that live in the same environments as their owners...

This work presents a method to determine the surface temperature of microphotonic medical implants like LEDs. Our inventive step is to use the photonic emitter (LED) employed in an implantable device as its own sensor and develop readout circuitry to accurately determine the surface temperature of the device. There are two primary classes of applications where microphotonics could be used in implantable devices; opto-electrophysiology, and fluorescence sensing. In such scenarios, intense light needs to be delivered to the target...

BACKGROUND: Delirium is a common problem that occurs in 5-50% of elderly individuals following surgery. Patients who develop delirium after surgery are at increased risk for serious complications. Recent studies suggest that patients with obstructive sleep apnea (OSA), a sleep disorder characterized by repeated episodes of complete or partial blockage of the upper airway - are at greater risk to develop delirium. OSA is more common in elderly individuals but is often undiagnosed. Identification and treatment of unrecognized OSA may reduce the incidence of postoperative delirium...

In most low and middle-income countries, chronic obstructive pulmonary disease (COPD) is on the rise. Areas covered: Unfortunately, COPD is a neglected disease in these countries. Taking sub-Saharan Africa as an example, in rural areas, COPD is even unknown regarding public awareness and public health planning. Programs for the management of COPD are poorly developed, and the quality of care is often of a low standard. Inhaled medication is often not available or not affordable. Tobacco smoking is the most common encountered risk factor for COPD...
