Antibiotics, steroids, and combination therapy in chronic rhinosinusitis without nasal polyps in adults.

Despite a lack of robust data regarding their efficacy, oral antibiotics and steroids remain two of the most common treatments for chronic rhinosinusitis without nasal polyps (CRSsNP). We sought to objectively compare the efficacy of antibiotics and steroids, independently and in combination, for the initial treatment of CRSsNP. To that end, we conducted a retrospective chart review of 100 patients-51 men and 49 women, age 20 to 85 years (mean: 50)-who were treated for CRSsNP from January 2010 through January 2015.

Effect of intranasal dexamethasone on endogenous cortisol level and intraocular pressure.

Background: Medical treatment of chronic rhinosinusitis with nasal polyposis (CRSwNP) centers on the administration of steroids. High-dose topical nasal steroids (HDTNS) have shown promising results with less systemic effects than oral steroids. One promising HDTNS is 0.

Effect of intranasal budesonide irrigations on intraocular pressure.

Background: Intranasal and oral corticosteroids are widely used in the management of chronic rhinosinusitis with nasal polyps (CRSwNP). Higher-dose topical nasal steroids (HDTNS) such as budesonide irrigations are increasingly used for long-term maintenance in these patients. Oral steroids have the potential to cause increased intraocular pressure (IOP) and glaucoma.

Disinfection of rigid nasal endoscopes following in vitro contamination with Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, and Haemophilus influenzae.

Importance: If not adequately cleaned, rigid nasal endoscopes (RNEs) have the potential to cause iatrogenic cross-contamination.

Objective: To test the efficacy of various disinfection methods in reducing bacterial load on RNEs in vitro.

Design And Setting: In vitro model.

The effect of intraoperative mupirocin irrigation on Staphylococcus aureus within the maxillary sinus.

Background: Antibiotic irrigations are occasionally used during endoscopic sinus surgery when gross mucosal infection is present. These irrigations are thought to flush out pathogenic bacteria and decrease the bacterial load within the mucosal surfaces. This treatment, however, has not been studied in vivo and it is unknown whether antibiotic rinses produce a quantitative reduction in pathologic bacteria within the sinus mucosa.

The incidence of maxillary sinus membrane perforation during endoscopically assessed crestal sinus floor elevation: a pilot study.

Transcrestal sinus membrane elevation is a surgical procedure performed to increase the bone volume in the maxillary sinus cavity. Because of visual limitations, the potential for maxillary sinus membrane perforations may be greater than with the lateral approach technique. The aim of this study was to macroscopically investigate ex vivo the occurrence of sinus membrane perforation during surgery using 3 transcrestal sinus floor elevation methods.

Canine fossa trephine is a beneficial procedure in patients with Samter`s triad.

Background: Canine fossa trephine (CFT) is an adjunctive technique to sinus surgery in patients with recalcitrant maxillary sinusitis. CFT allows for disease clearance in areas of the maxillary sinus that are hard to reach with standard endoscopic techniques. The objective of this study was to compare the surgical outcome of CFT to standard middle meatal antrostomy (MMA) in matched patients with the severely diseased maxillary sinus.

Epigenetics of chronic rhinosinusitis and the role of the eosinophil.

Background: One theory for the pathogenesis of chronic rhinosinusitis with nasal polyps (CRSwNP) involves aberration in the expression of genes that maintain the sinonasal innate immune system. We propose that the alteration in gene expression seen in CRSwNP is a result of oxidative byproducts of eosinophils. Activated eosinophils and neutrophils may lead to the production of hypobromous acid (HOBr) and hypochlorous acid (HOCL) and the posttranslational modification products 5-bromocytosine (5BrC) and 5-chlorocytosine (5ClC), respectively.

The impact of intraoperative saline irrigations on bacterial load within the maxillary sinus.

Background: Saline irrigations are routinely employed during endoscopic sinus surgery to remove mucous and debris from the sinus cavities. What is unknown is whether this results in a quantitative reduction in pathologic bacteria within the sinus mucosa. The objectives of this study were to quantify the amount of 5 different bacteria (Staphylococcus aureus, Haemophilus influenzae, Pseudomonas aeruginosa, coagulase-negative Staphylococcus (CNS), and Streptococcus pneumoniae) within the maxillary sinus and to determine the impact of saline irrigations on bacterial counts.

Disinfection of flexible fiberoptic laryngoscopes after in vitro contamination with Staphylococcus aureus and Candida albicans.

Objective: To determine the efficacy of various cleaning and disinfective methods in reducing bacterial and fungal load on flexible fiberoptic laryngoscopes (FFLs).

Design: In vitro model.

Subjects: Flexible fiberoptic laryngoscopes contaminated with Staphylococcus aureus and Candida albicans.

Case studies in the surgical management of nasal airway obstruction.

This article focuses on the workup and treatment of two distinct cases of nasal obstruction. The first case has to do with a 24-year old male who presented with a brief seizure. Review of systems was positive only for longstanding right nasal obstruction.

Office CO2 laser turbinoplasty.

We conducted a prospective study of office carbon dioxide (CO(2)) laser turbinoplasty as a treatment for symptoms related to turbinate dysfunction in 58 patients. All patients completed surveys before and 1 month after treatment, and 23 patients completed longer-term follow-up surveys 8 to 24 months postoperatively. The 1-month postoperative assessments demonstrated a trend toward symptom improvement, as many patients reported a decrease in their use of pretreatment medications.

Ultrasound-guided fine needle aspiration biopsy of thyroid nodules performed in the office.

Introduction: The majority of thyroid fine needle aspiration biopsies (FNAB) today are performed in the office freehand by palpation. Not infrequently, patients are sent to radiology for an ultrasound-guided FNAB (USG-FNB). Real-time ultrasound (US) allows for continuous visualization of the needle during insertion and sampling.

Hypothyroidism following hemithyroidectomy for benign nontoxic thyroid disease.

Hypothyroidism following hemithyroidectomy for benign nontoxic thyroid disease is an underappreciated phenomenon. Up until recently, it was common practice for physicians to place post-hemithyroidectomy patients on thyroid suppression therapy during the immediate postoperative period. That practice began to fall out of favor as a result of two developments: (1) the publication of data that put into question the efficacy of levothyroxine therapy for preventing recurrent disease or thyroid growth and (2) a heightened awareness of the morbidity associated with levothyroxine.

Superantigens and chronic rhinosinusitis: skewing of T-cell receptor V beta-distributions in polyp-derived CD4+ and CD8+ T cells.

Background: Recent studies have suggested that Staphylococcus aureus secrete superantigenic toxins that play a role in the etiology of chronic rhinosinusitis with nasal polyposis (CRSwNP). Twenty S. aureus superantigens (SAg's) have been identified, each of which bind the V beta-region of the T-cell receptor (TCR) outside the peptide-binding site.

Superantigens and chronic rhinosinusitis II: analysis of T-cell receptor V beta domains in nasal polyps.

Background: The superantigen (SAg) hypothesis of chronic rhinosinusitis (CRS) suggests that toxins within the nose stimulate massive oligoclonal expansion of T-cell populations with subsequent eosinophil recruitment and tissue inflammation. SAgs are capable of activating 1 x 10(4) more lymphocytes than conventional antigens by binding specific Vbeta-domains of the T-cell receptor (TCR). The net effect is skewing from the normal Vbeta-profile by oligoclonal expansion of specific domains.

Chronic rhinosinusitis and superantigens.

This article discusses the potential role of bacterial superantigens (SAgs) in chronic rhinosinusitis with nasal polyposis (CRS/NP). First, it briefly describes SAgs, focusing on how they interact with the immune system by binding to T-cell receptors (TCR) and major histocompatibility complex (MHC) class II molecules. Second, it discusses the role of SAgs in other chronic inflammatory diseases.

Superantigens and chronic rhinosinusitis: detection of staphylococcal exotoxins in nasal polyps.

Objective/hypothesis: The role of infectious agents in the etiology of chronic rhinosinusitis with nasal polyposis (CRSwNP) remains unclear. Recent studies have provided indirect evidence of exposure to staphylococcal exotoxins in the blood and polyp tissue of patients with CRSwNP. These exotoxins have the capacity to act as superantigens, bypassing normal antigen processing and directly stimulating a massive inflammatory response.

Aging and olfactory and taste function.

This article focuses on the change in olfaction and taste with aging. It discusses histopathology with an emphasis on age-related changes, causes of chemosensory dysfunction in the elderly, how to evaluate a patient with dysfunction, useful tests and imaging, clinical consequences of chemosensory impairments, and available treatment options.

Role of intrathyroidal calcifications detected on ultrasound as a marker of malignancy.

Objectives: Clinically palpable thyroid nodules are present in between 4% and 7% of the population, with only a small percentage of those harboring malignancy. Thus, it is important to find a cost-effective way to determine which nodules are more likely to be malignant. The purpose of this study was to evaluate the use of intrathyroidal calcifications detected on ultrasound as a risk factor for malignancy.
