RESUMO
OBJECTIVES: Obstructive sleep apnea (OSA) is a sleep-related breathing disorder caused by repetitive obstruction of the upper airway; this impairs gaseous exchange, resulting in hypoxia, hypercapnia, and frequent arousals. Excessive daytime sleepiness (EDS) is a common daytime symptom of OSA. EDS manifests as fatigue and impaired attention, leading to poor performance at work and falling asleep while driving, which is a major socioeconomic problem. Therefore, it is important to properly treat EDS and accurately predict the response to treatment. However, few studies have compared OSA patients showing and not showing improvement in EDS. Therefore, this study aimed to objectively analyze and compare EDS improvement and non-improvement groups. SUBJECTS AND METHODS: We retrospectively reviewed the medical records of 57 OSA patients with EDS. Patients were divided into two groups according to the improvement in EDS after positive airway pressure (PAP) device treatment. We analyzed differences in clinical records including patients' age, sex, history of smoking, hypertension, diabetes, myocardial infarction, and cerebrovascular disease between the two groups. Systolic, diastolic blood pressure, blood test including blood glucose, total cholesterol, high- and low-density lipoprotein cholesterol, and triglyceride levels were also analyzed. Polysomnography (PSG) data, PAP device treatment compliance and scores of questionnaires related to various psychiatric symptoms, subjective sleep quality between the two groups were also analyzed. RESULTS: There was no statistically significant difference in age, gender, or past medical history between the two groups. Systolic and diastolic blood pressure, and blood test results, were also not significantly different. Among the questionnaires related to various psychiatric symptoms, the groups showed statistically significant differences in Social Avoidance and Distress Scale (SADS) and Fear of Negative Evaluation (FNE) scores (P = 0.001 and 0.020, respectively). The group differences in the scores on the other questionnaires were not significantly different. Among the PSG items, significant group differences were observed in the percentage of stage 2 non-REM sleep (N2%, P = 0.023), apnea index (AI, P = 0.005), apnea-hypopnea index (AHI, P = 0.023), and frequency of 3 % oxygen desaturation (ODI3, P = 0.001). No obesity-related parameters showed significant group differences. The percentage of days on which a PAP device was used (out of 90 days; PAP%) and percentage of days on which a PAP device was used for >4 h (Time4%) did not differ significantly. CONCLUSIONS: The SADS, FNE, AI, AHI, N2%, and ODI3 parameters differed significantly between the EDS improvement and non-improvement groups. These parameters may help clinicians treat and predict the prognosis of patients suffering with EDS.

OBJECTIVE: Paranasal sinus mucoceles are accumulation of mucoid secretions and desquamated epithelium within the sinus causing distension of its wall. They occur mostly in the frontal and ethmoid sinuses. Patients with giant frontal or ethmoidal sinus mucoceles suffer from orbital symptoms such as proptosis, visual disturbance, periorbital swelling, pain, or visual disturbance mostly, but they can also have rhinologic or neurologic symptoms. The purpose of this study is to evaluate the efficacy of endoscopic marsupialization for treating giant frontal and ethmoidal sinus mucoceles causing orbital symptoms. METHODS: This study was a retrospective, consecutive clinical review of patients with giant frontal and ethmoidal sinus mucoceles with orbital symptoms, who were treated by endoscopic marsupialization between January 2012 and August 2019. Medical records including age, gender, nasal and orbital symptoms, imaging findings, and surgical methods were reviewed. RESULTS: There were 15 patients with giant frontal and/or ethmoidal sinus mucoceles accompanied with orbital symptoms. The mean age of the patients was 50.5 years. One patient had previously undergone endoscopic sinus surgery for chronic rhinosinusitis. Within 15 patients, the main orbital symptoms were visual disturbance (6 patients), proptosis (8 patients), eyelid swelling (6 patients), and periorbital pain (1 patient). Other symptoms included nasal congestion, rhinorrhea, and headache. All patients underwent endoscopic marsupialization of the mucocele and had improvement in nasal and orbital signs and symptoms. CONCLUSION: Endoscopic marsupialization is an effective treatment for giant frontal and ethmoidal mucoceles with orbital symptoms.

A congenital bladder diverticulum (CBD) is caused by inherent muscular weakness instead of obstruction of the bladder outlet. The major clinical conditions are recurrent urinary tract infection (UTI) and voiding dysfunction. This report describes a 15-year-old male adolescent who developed sudden visual disturbance resulting from hypertensive retinopathy. The cause of hypertension was bilateral obstructive uropathy caused by enlarged paraureteral bladder diverticula. After the non-functioning right kidney and ureter and the bilateral diverticula were removed, the left ureter was reimplanted in the bladder. Pathologic findings showed chronic pyelonephritis and partial loss of the bladder musculature in the diverticular wall. This observation indicates that dilated CBD can cause latent UTI, ureteral obstruction, hydronephrosis, and secondary hypertension.

PURPOSE: Airway pathology in children with atopic asthma can be reflected by the concave shape of the maximal expiratory flow-volume (MEFV) curve and high fractional exhaled nitric oxide (FeNO) values. We evaluated the capacity of the curvilinearity of the MEFV curve, FeNO, and their combination to distinguish subjects with atopic asthma from healthy individuals. METHODS: FeNO and angle ß, which characterizes the general configuration of the MEFV curve, were determined in 119 steroid-naïve individuals with atopic asthma aged 8 to 16 years, and in 92 age-matched healthy controls. Receiver operating characteristic (ROC) curve analyses were performed to determine the cutoff points of FeNO and angle ß that provided the best combination of sensitivity and specificity for asthma detection. RESULTS: Asthmatic patients had a significantly smaller angle ß and higher FeNO compared with healthy controls (both, P<0.001). For asthma detection, the best cutoff values of angle ß and FeNO were observed at 189.3° and 22 parts per billion, respectively. The area under the ROC curve for the combination of angle ß and FeNO improved to 0.91 (95% confidence interval [CI], 0.87-0.95) from 0.80 (95% CI, 0.75-0.86; P<0.001) for angle ß alone and 0.86 (95% CI, 0.82-0.91; P=0.002) for FeNO alone. In addition, the combination enhanced sensitivity with no significant decrease in specificity. CONCLUSION: These data suggest that the combined use of the curvilinearity of the MEFV curve and FeNO is a useful tool to differentiate between children with and without atopic asthma.
RESUMO
PURPOSE: The prevalence rates of metabolic syndrome (MetS) and percentile distribution of insulin resistance (IR) among Korean children and adolescents were investigated. The cutoff values of IR were calculated to identify high-risk MetS groups. METHODS: Data from 3,313 Korean subjects (1,756 boys and 1,557 girls, aged 10-18 years) were included from the Korean National Health and Nutrition Examination Survey conducted during 2007-2010. Three different sets of criteria for MetS were used. Indirect measures of IR were homeostasis model assessment (HOMA-IR) and triglyceride and glucose (TyG) index. The cutoff values of the HOMA-IR and TyG index were obtained from the receiver operation characteristic curves. RESULTS: According to the MetS criteria of de Ferranti el al., Cook et al., and the International Diabetes Federation, the prevalence rates in males and females were 13.9% and 12.3%, 4.6% and 3.6%, and 1.4% and 1.8%, respectively. Uses these 3 criteria, the cutoff values of the HOMA-IR and TyG index were 2.94 and 8.41, 3.29 and 8.38, and 3.54 and 8.66, respectively. The cutoff values using each of the 3 criteria approximately corresponds to the 50th-75th, 75th, and 75th-90th percentiles of normal HOMA-IR and TyG index levels. CONCLUSION: This study describes the prevalence rates of MetS in Korean children and adolescents, an index of IR, and the cutoff values for MetS with the aim of detecting high-risk groups. The usefulness of these criteria needs to be verified by further evaluation.
