OBJECTIVES: The effects of air pollutants on upper airway disease development have been seldom studied. In this study, we evaluated the effects of air pollution on the prevalence of ENT diseases. METHODS: We identified cases of ENT disease occurring in 2009, as recorded by the Korea National Health and Nutrition Examination Survey, and explored their associations with the levels of five air pollutants: sulfur dioxide (SO₂), nitrogen dioxide (NO₂), ozone (O₃), carbon monoxide (CO), and particulate matter (PM₁₀ particles; particulates ≤10 μm in aerodynamic diameter). Subjects diagnosed with at least one of the five studied ENT diseases were included in analysis, but those aged under 19 years were excluded. Linear associations between ENT disease frequency and pollutant levels were evaluated by calculating Spearman correlations. After adjusting for age, gender, and geographic region, multivariate logistic regression was used to obtain odds ratios (OR) with 95% confidence intervals (CI). RESULTS: A total of 7,399 subjects with ENT diseases were identified. A linear association was evident between PM₁₀ concentration and the frequency of septal deviation (Spearman coefficient, 0.507; P=0.045). After adjustment, the PM₁₀ level was associated with high odds ratios for chronic rhinosinusitis (1.22; 95% CI, 1.02 to 1.46) and septal deviation (1.43; 95% CI, 1.22 to 1.67). Both of these conditions were more prevalent in males. CONCLUSION: We found that increased ambient concentrations of PM₁₀ particles were clearly associated with increased the risk of chronic rhinosinusitis and septal deviation; the exposure-response relationship was definitive.

Erythromelalgia is a rare condition, of uncertain etiology, characterized by episodic erythema, intense burning pain and warmth of the hands and/or feet. We present here a case of erythromelalgia that was almost mistaken for lower leg pain of spinal origin. The diagnosis is based on a thorough history and physical exam during a painful episode along with diagnostic test to exclude other causes. A 69-year-old man developed recurrent attacks of redness, swelling and burning painful sensations of both feet. His symptom was aggravation of pain with warm water immersion. His symptom improved by antidepressant and steroid. To be learned an important general lesson is to pay attention to performing extensive diagnostic and therapeutic procedures. It should be appreciated that discontinuation of medication can also be used as a simple diagnostic test for clinical syndromes, such as erythermalgia.

The authors have experienced two cases of general anesthesia for repair of congenital diaphragmatic hernia. Both patients were female (1 year 5 months and 8 months of age) and had left sided Bochdalek hernia. Anesthesia was maintained with halothane-oxygen using nonrebreathing system with Ruben valve, and the patients tolerated the whole procedure very well. The importance of maintaining adequate ventilation with high concentrations of oxygen and avoiding abdominal distension has been stressed.

Otitis media is defined as inflammation of the middle ear, including the auditory ossicles and the Eustachian tube. Otitis media is a major health problem in many societies. The causes of otitis media includes infection and anatomic/physiologic, host, and environmental factors. In general, otitis media is a childhood disease, and anatomic and physiologic changes have great effects on its development. Thus, in vitro or human experimental studies of otitis media are difficult. Several experimental animal models have been introduced to investigate the pathogenesis and treatment of otitis media. However, none are ideal. The aim of this review is to provide a brief overview of the current status of animal models of otitis media with effusion, acute otitis media, and cholesteatoma. This review will assist determination of the most appropriate animal models of otitis media.

The effect of alloxan-diabetic rat fed with normal, high fat, low protein and high protein diets on the rate of urea production and the activities of enzymes associated with the urea cycle (ornithine transcarbamoylase, E.C. 2.1.3.3, OTC; arginase, E.C. 3.5.5.1) have been studied in intact and isolated perfused liver. The amount of urea excretion was the highest in the high protein diet group. When each diet group was treated with alloxan, total urea excretion showed little differences between each diet group and its corresponding control group with the exception being in the normal diet group. However, the enzyme activity of OTC was increased significantly by alloxan treatment in low and high protein diet groups as compared to corresponding control groups. Similar results were obtained in arginase activity, although the magnitude of the change was less marked. In liver perfusion experiments on rats treated with alloxan, the amount of urea production and changes in OTC and arginase activity were very similar with those in the intact liver. These results suggest that alloxan treatment in normal diet group causes an increase in urea excretion both in intact and perfused liver regardless of changes in enzyme activities and total urea excretion, and enzyme activities are affected by changes in dietary components but the changes of enzyme activities may not correlate with total urea excretion.

Tinnitus is defined as auditory perception without external sound. There is currently no cure for tinnitus. Cognitive behavioral therapy (CBT) is a tinnitus treatment that addresses the affected individual's reaction to tinnitus. It aims not to eliminate auditory perception as sound but to reduce or correct one's negative response to tinnitus. CBT identifies negative automatic thought and then evaluates its validity with the patient. It also aims to change negative automatic thought to more positive and realistic thought. In this way, tinnitus sufferers can function well despite the presence of tinnitus. Many studies have supported the efficacy of CBT for treating tinnitus. A meta-analysis of CBT for tinnitus also concluded that CBT is effective in treating tinnitus. Thus, CBT is considered a good option for treating tinnitus. We herein discuss the use of CBT for tinnitus with a literature review.

Conventional impedance audiometry uses only specific tympanometric frequencies (e.g., 226 Hz) and cannot test above 1500 Hz. As many hearing frequencies must be evaluated when diagnosing middle ear pathologies, wideband clicks stimulating tympanometric receptors from 226 to 8000 Hz are commonly delivered. Since wideband tympanometry (WBT) was introduced in 1993, several studies have explored its clinical utility. WBT yields information on absorbances at various frequencies and pressures. Recently, WBT has become increasingly used to diagnose and monitor the hearing of newborns and patients with otosclerosis, ossicular chain disruptions, tympanic perforations, superior semicanal dehiscence syndrome, and middle ear effusions. WBT is also employed for pre/postoperative monitoring using non-pressurized wideband absorbance. Here, we review the concept of WBT, the basic mechanism, and the clinical applications.
