RESUMEN

BACKGROUND AND OBJECTIVES: Unilateral sinus lesions can be caused by many diseases and exact preoperative diagnosis is often difficult to make. The aims of this study were to evaluate the recent trends for prevalence of unilateral sinus lesions and find useful factors in differential diagnosis. MATERIALS AND METHOD: Preoperative clinical diagnosis including computed tomography (CT) images, endoscopic findings and postoperative diagnosis based on pathology were assessed retrospectively in 384 consecutive patients who underwent unilateral sinus surgery from 2004 to 2013. RESULTS: Chronic bacterial rhinosinusitis (40%) was the most common cause of unilateral sinus lesions, followed by fungal sinusitis (21%), benign and malignant tumors (14%), and odontogenic sinusitis (11%). The incidence of odontogenic sinusitis has recently increased and mismatches of pre- and post-operative diagnosis were commonly found among patients with chronic bacterial rhinosinusitis, fungal sinusitis, or odontogenic sinusitis. Microcalcification in fungal sinusitis and dental lesions in odontogenic sinusitis were confirmed as critical factors by logistic regression analysis. CONCLUSION: The incidence of odontogenic sinusitis has been increasing steadily over the last 10 years. The findings of microcalcification and dental lesions on CT could provide crucial information to make a precise preoperative diagnosis among chronic bacterial rhinosinusitis, fungal sinusitis and odontogenic sinusitis.

RESUMEN

Acute rhinosinusitis can usually be managed by appropriate medical therapy, but it may also extend to the periorbital area in some complicated cases. Periorbital necrotizing fasciitis is uncommon among orbital complications, but can be fatal if it leads to soft tissue infection characterized by extensive necrosis and gas formation in the fascia and subcutaneous tissue. Immunocompromised states such as old ages, diabetes mellitus, alcoholics, and chronic renal failure have been reported to be predisposing factors, but the disease has also been detected in healthy patients. If proper treatment is not performed at the right time, necrotizing fasciitis can lead to systemic toxicity, multisystem organ failure, and eventual death. Therefore, early diagnosis and treatment are important. We report a case of periorbital necrotizing fasciitis that occurred in a healthy 30-year-old male patient with acute rhinosinusitis, which was treated with a combination of intravenous antibiotics and debridement of necrotic tissue and local wound management.

RESUMEN

Ectopic thyroid gland is usually located along the development path of thyroid in the anterior midline of the neck. However, its occurrence within the mediastinum is very rare. Mediastinal ectopic thyroid cyst is usually benign and asymptomatic, but we experienced a case of the mediastinal ectopic thyroid cyst inducing a severe airway obstruction in a 45-year-old male. The mass had no connection to the cervical thyroid gland and histological examination revealed a mediastinal cyst of an ectopic thyroid. We present the case with a review of the related literatures.

RESUMEN

BACKGROUND AND OBJECTIVES: The aim of this study was to compare between preoperative and postoperative voices by subjective auditory perceptual evaluation and objective acoustic analysis. The study also analyzed the acoustic parameters that best reflected the auditory perceptual characteristics in laryngeal microsurgery. SUBJECTS AND METHOD: The records of 49 patients who had been diagnosed as benign vocal fold mucosal diseases and had undergone laryngeal microsurgery were retrospectively analyzed. Preoperative and postoperative voices were assessed by auditory perceptual evaluation using the GRBAS Scale and acoustic analysis using Multi-Dimensional Voice Program (MDVP) and Analysis of Dysphonia in Speech and Voice (ADSV). Correlation between auditory perceptual characteristics and acoustic parameters was analyzed. RESULTS: Auditory perceptual evaluation showed that the patients' voices were improved after the operation. Several acoustic parameters of MDVP related to short-term and long-term variability showed significant improvement. Also, there were significant differences in several cepstral/spectral parameters of ADSV after operation. In the correlation analysis, the overall grade (G) of the GRBAS Scale showed highest correlation with the cepstral spectral index of dysphonia (CSID) (r=-0.700). The roughness (R) of GRBAS Scale was correlated with the smoothed amplitude perturbation quotient of long-term variability of MDVP (r=0.468), breathiness (B) with cepstral peak prominence (r=-0.703) and strain (S) with CSID (r=0.650) (p<0.01). CONCLUSION: Our results showed that the acoustic parameters were related to the long-term variability of MDVP, and the parameters of cepstrum/spectrum were useful for the objective assessment of voice quality in patients who received laryngeal microsurgery. These parameters were also useful for the quantification of voice quality and abnormality of phonation.

RESUMEN

BACKGROUND/AIMS: As bacterial resistance to antimicrobial agents has grown due to the increasing use of antimicrobial agents, we sought to evaluate the suitability of ceftriaxone usage (representative of third generation cephalosporins) at 10 university hospitals in Korea. METHODS: We prospectively evaluated the appropriateness of antibiotic usage in 400 adult patients who received ceftriaxone between February 1, 2006 and June 30, 2006. Drug utilization evaluation (DUE) methods were based on standards set forth by the American Society of Hospital Pharmacists. The DUE criteria used in this study were modified to be more suitable in our hospital setting: justification of drug use, critical and process indications, complications, and outcome measures. RESULTS: The average patient age was 64.4 years. The utilization of ceftriaxone was appropriate in 262 cases (65.5%) for the justification of use, while inappropriate use was observed in 138 cases (34.5%). Common reasons for inappropriate use of ceftriaxone included continued empiric use for presumed infections, prophylactic perioperative injection, and empiric therapy for fever. Most of the critical indications showed a high rate of suitability (66.5-98.5%). Complications occurred in 37 cases (9.3%). With respect to outcome measures, clinical responses were observed in 60.7% of cases, while only 15.7% of cases showed evidence of infection eradication via negative cultures. CONCLUSIONS: Appropriate use (65.5%) of ceftriaxone was higher than inappropriate use (34.5%) at university hospitals in Korea. Inappropriate utilization, however, including continued empiric use for presumed infections and prophylactic perioperative injection remained high. Intensification of educational programs and antibiotic control systems for ceftriaxone is needed to improve the suitability of antimicrobial use.
