Antibacterial Effect of Hypochlorous Acid Solution on Nasal Discharge from Patients with Chronic Rhinosinusitis.

Purpose: The antibacterial effect of hypochlorous acid (HOCl) solution on nasal secretion of patients with chronic rhinosinusitis (CRS) was investigated.

Materials And Methods: Five swab specimens were collected from the middle meatus of CRS patients. The first one was placed directly in a Thanswab tube while all of the others were placed randomly into 4 glass tubes containing either HOCl solution, normal saline (NS), 75% alcohol, or povidone-iodine (PVPI) solution for one minute in the first part and for 5 minutes in the second part of the study before transfer to a Thanswab tube.

Postoperative antibiotic care after functional endoscopic sinus surgery.

Background: Antibiotics are used routinely in the postoperative care of functional endoscopic sinus surgery (FESS), but their efficacy has not been well evaluated.

Methods: Patients with chronic rhinosinusitis who underwent FESS were enrolled in this study. They were randomly divided into two groups: a study group and a control group.

Developing a rabbit model of rhinogenic chronic rhinosinusitis.

Objective: The purpose of this study was to develop a rabbit model of rhinogenic chronic rhinosinusitis (CRS).

Methods: New Zealand white rabbits were used and divided into two groups. In group A rabbits, a piece of Merocel (Medtronic-Xomed, Jacksonville, FL) was inserted into one nasal cavity and the other was left undisturbed as control.

Amphotericin B irrigation for the treatment of chronic rhinosinusitis without nasal polyps: a randomized, placebo-controlled, double-blind study.

Background: Fungus-driven inflammation is proposed to play an important role in the pathogenesis of chronic rhinosinusitis (CRS). Previous studies tested the efficacy of intranasal antifungal agents for patients with nasal polyps. The purpose of this study was to evaluate the efficacy of intranasal amphotericin B (AMB) in patients who have CRS without nasal polyps (CRSsNP).

Bacteriology of chronic sinusitis in relation to middle meatal secretion.

Background: The bacteriology of chronic sinusitis has been studied widely, but some factors may affect the results, such as sample sources and sampling techniques. However, whether the presence of secretion in the middle meatus affects the culture result has been studied rarely.

Methods: When patients with chronic sinusitis underwent functional endoscopic sinus surgery, swab specimens were taken from the ipsilateral middle meatuses and ethmoid sinuses under endoscopic guidance.

Nasal mycology of chronic rhinosinusitis.

Background: Ponikau used a novel collection and culturing method to recover fungi from nasal secretion in patients with chronic rhinosinusitis. The same method had been used previously in Europe with a similar result. However, the use of Ponikau's method has not been reported in Asia.

Correlation between bacteriology and computed tomography staging for chronic sinusitis.

In this study we report on the correlation between bacteriology and disease severity staging by computed tomography (CT) for chronic sinusitis. When patients with chronic sinusitis underwent functional endoscopic sinus surgery (FESS), swab specimens were taken from the ipsilateral middle meati and ethmoid sinuses under endoscope guidance. The severity of chronic sinusitis was evaluated by pre-operative CT scans.

Is combination antimicrobial therapy required for urinary tract infection in children?

This retrospective study examined the characteristics of 338 pediatric patients presenting with a first episode of symptomatic urinary tract infection at Taichung Veterans General Hospital from November 1996 to December 2001. Escherichia coli was the most common pathogen (72.5%), followed by Proteus mirabilis (8.

Bacteriology of chronic maxillary sinusitis in relation to sinoscopic appearance.

Background: The bacteriology of chronic maxillary sinusitis in relation to different sinoscopic appearances is reported in this study.

Methods: When transantral sinoscopy via an anterior wall puncture was used to examine the maxillary antra in patients with chronic maxillary sinusitis, the sinoscopic appearances were divided into five types. Maxillary antra in which ostia were recognized under the endoscope and no secretion existed were classified as type 1.

Correlation between bacteriology of the middle meatus and ethmoid sinus in chronic sinusitis.

In this study we report on the correlation between the bacteriology of the middle meatus and ethmoid sinus in chronic sinusitis. When patients with chronic sinusitis underwent functional endoscopic sinus surgery (FESS), swab specimens were taken from the middle meati before surgery. After removing the ethmoid bullae, swab specimens were taken from the ethmoid sinuses.
