Obstructive sleep apnea is a common condition, primarily caused by narrowing of the nasal and pharyngeal airway. Treatment with continuous positive airway pressure (CPAP) is considered the first line of therapy, but long-term compliance is only about 40%, often because of nasal obstruction. Any nasal obstruction can worsen CPAP compliance. Treatment of the nasal obstruction with topical nasal steroid sprays or nasal dilators has been shown to improve sleep disordered breathing. Surgical treatment of nasal obstruction, has been shown to improve sleep disordered breathing, as well as CPAP requirement and compliance with CPAP...

BACKGROUND: Wide excision or Mohs surgery is the standard treatment of skin squamous cell carcinoma (SCC). Superficial SCC or tumor smaller than 1 cm has been treated successfully with open spray cryosurgery. Larger tumor may not be as effective because tissue destruction is usually superficial. Intralesional cryosurgery (IC) may provide a deeper and better cell killing effect in larger tumors. We investigated the safety and efficacy of treating nodular SCC in 4 patients with IC. METHODS: Four patients with nodular SCC/keratoacanthoma (tumor size, 1-2...

Vesicular and colloidal delivery systems can be designed to control drug release spatially and temporally to improve drug efficacy and side effect profiles. Niosomes (vesicles prepared from nonionic surfactants in aqueous media) are gaining interest as an alternative vesicular delivery system as they offer advantages such as biocompatibility, chemical stability, low cost, high purity and versatility. However, the physical stability of niosomes, like other vesicular systems, is limited by vesicle fusion, aggregation and leakage...

OBJECTIVES: Local infiltration with lidocaine is a frequently used measure to prevent pain during arterial cannulation. Its administration is associated with pain. Vapocoolants like ethyl chloride or alkanes also affect rapid-onset anesthesia. However, their administration causes less discomfort compared with administration of lidocaine. The effectiveness of vapocoolants in mitigating discomfort associated with arterial cannulation never has been studied. The authors therefore compared vapocoolant with lidocaine for reducing discomfort caused by arterial cannulation...

Chronic rhinosinusitis with nasal polyposis (CRSwNP) is an inflammatory disease of the sinonasal passages. Similar to other chronic inflammatory diseases, an essential component of the long-term control is prolonged medical therapy. To minimize the risk of adverse effects and cumulative complications of systemic medications, topical sinonasal therapy has become the primary strategy for prolonged medical therapy. The objective of this review article is to describe the evidence for the most common topical sinonasal delivery techniques...

Importance: Evidence from previous studies suggests that furosemide may be effective in reducing the recurrence of polyps after sinus surgery. However, the evidence is limited and insufficient, and further investigations are required. Objective: To assess the effect of topical furosemide on recurrence rate of rhinosinusal polyposis after endoscopic sinus surgery. Design, Setting, and Participants: Triple-blind randomized clinical trial of patients aged 18 to 60 years with chronic rhinosinusitis associated with polyposis who did not respond to medical treatment and were candidates for endoscopic sinus surgery at Besat Hospital, Hamadan University of Medical Sciences, from April 2014 to June 2015...

Over the last 20 years the majority of emerging infections which have spread rapidly across the globe have been respiratory infections that are spread via droplets, a trend which is likely to continue. Aerosol spray generation in the dental surgery has the potential to spread such infections to staff or other patients. Although the diseases may differ, some common approaches can reduce the risk of transmission. Dental professionals should be aware of areas affected by emerging infections, the incubation period and the recent travel history of patients...

BACKGROUND: Perioperative respiratory adverse events (PRAEs) are a major cause of morbidity and mortality associated with pediatric anesthesia. Topical lidocaine administration reduces risk of PRAE in children undergoing elective endotracheal intubation. However, definitive evidence of its efficacy remains elusive, due, in part, to the wide variability in the methodology for spraying topical lidocaine. In this randomized controlled double-blind clinical trial, we sought to evaluate the effect of site-directed topical airway lidocaine, sprayed directly onto supraglottic, glottis, and subglottic areas, on the incidence of PRAE...

OBJECTIVE: Complications of cardiopulmonary bypass (CPB) are rare, but life-threatening events that need prompt and rehearsed actions involving a team. This is not adequately taught to cardiothoracic surgical trainees. The objective of this study was to assess the knowledge of cardiothoracic trainees required to manage these events after simulation-based vs. lecture-based teaching. PARTICIPANTS AND DESIGN: Totally, 17 cardiac surgical trainees with no formal teaching in intraoperative complications of CPB management were randomly assigned by computer to either a study group receiving simulation-based complications of CPB teaching via the Orpheus simulator (n = 9) or a control group receiving complications of CPB teaching via a lecture (n = 8)...

Optical fluorescence-guided imaging is increasingly used to guide surgery and endoscopic procedures. Activatable probes are particularly useful because of high target-to-background ratios that increase sensitivity for tiny cancer foci. However, green fluorescent activatable probes suffer from interference from autofluorescence found in biological tissue. The purpose of this study was to determine if dynamic imaging can be used to differentiate specific fluorescence arising from an activated probe in a tumor from autofluorescence in background tissues especially when low concentrations of the dye are applied...

OBJECTIVES: Despite improved survival in children with hypoplastic left heart syndrome (HLHS), significant concern persists regarding their neurodevelopmental (ND) outcomes. Previous studies have identified patient factors, such as prematurity and genetic syndromes, to be associated with worse ND outcomes. However, no consistent relationships have been identified among modifiable management factors, including cardiopulmonary bypass strategies, and ND outcomes after cardiac surgery in infancy...
