BACKGROUND AND OBJECTIVES: Nasolabial cysts are relatively rare and are sometimes confused with tumors due to progressive enlargement. Treatment of a nasolabial cyst consists of sublabial excision or endonasal endoscopic marsupialization (EEM). The purpose of this study was to investigate the clinical features of nasolabial cysts in order to provide a basis for correct diagnosis and treatment. MATERIALS AND METHODS: Sixty-four patients with a nasolabial cyst were surgically treated between December, 1989 and January, 2010 at the Department of Otolaryngology, Asan Medical Center. Their clinical features, radiologic and histopathologic findings, and treatment and outcomes were retrospectively analyzed. RESULTS: The patients comprised 51 (80%) women and 13 men (20%), with ages ranging from 16 to 69 years with a mean of 43 years. Swelling of the nasolabial fold was the most frequently experienced symptom. There was no right or left side preponderance. Sublabial excision was applied in 57 cases (89%), while seven cases (11%) were treated via the endonasal approach. There was no case of recurrence. CONCLUSION: Nasolabial cysts should be suspected in patients with swelling of the nasolabial area and nasal obstruction. Enhanced CT may be needed to differentiate from tumors, odontogenic cysts, or other inflammatory lesions. Nasolabial cysts can be successfully treated via sublabial or endonasal approaches. Postoperative complications or recurrence is very rare.

Two cases of familial asymmetric septal hypertrophy diagnosed by myocardial biopsy and clinical studies are reported with literature reviewed. Myocardial biopsy was done at right ventricular septal wall, and pedigree of family members was observed clinically and examined by noninvasive methods including chest X-ray and echocardiography.

Regenerated bone volume (mm3) of 1% TC-loaded SFM, SFM, and control were 36.56+/-8.50, 25.86+/-8.17, and 19.09+/-5.07 at 8 weeks postoperatively, respectively (P<0.05).CONCLUSION: The 1% TC-loaded SFM showed more bone regeneration than the SFM and the uncovered control, in guided bone regeneration.]]>

OBJECTIVES: Positive airway pressure (PAP) is considered a standard treatment for moderate-to-severe obstructive sleep apnea (OSA) patients. However, compliance with PAP treatment is suboptimal because of several types of discomfort experienced by patients. This study investigated compliance with PAP therapy, and affecting factors for such compliance, in OSA patients. METHODS: We performed a survey on 69 patients who engaged in PAP therapy between December 2006 and November 2007. After diagnostic polysomnography and manual titration, patients trialed PAP using the ResMed instrument and explored autoadjusting PAP (APAP), continuous PAP (CPAP), and flexible PAP (using expiratory pressure relief [EPR]) at least once every week for 1 month. Compliance measures were mean daily use (hr), percentage of days on which PAP was used, and percentage of days on which PAP was used for >4 hr. Data were obtained at night using the software Autoscan version 5.7(R) of the ResMed Inc. We obtained data on anthropometric (age, BMI, neck circumflex, Epworth sleepiness scale, Pittsburgh Sleep Quality Index, hypertension, alcohol intake), polysomnographic data (severity of apnea-hypopnea index [AHI], proportion of nonsupine sleep time, position dependence of sleep), PAP mode and AHI during PAP use for affecting factors. RESULTS: After 1 month, 41 of the 69 patients (59.4%) were pleased with PAP therapy and purchased instruments. Twenty-four patients (34.7%) used PAP for more than 3 months. The percentage of days on which PAP was used was statistically higher in patients with hypertension than in normotensive patients (P=0.003). There were negative correlations 1) between nonsupine position sleep time and percentage of days on which PAP was used (r=-0.424, P=0.039), and 2) between the AHI during PAP use and the percentage of days on which PAP was used for >4 hr (r=-0.443, P=0.030). There were no statistical differences between AHI, BMI, PAP pressure, or other measured parameters, on the one hand, and compliance, on the other. CONCLUSION: The affecting factors for PAP use were hypertension history, sleep posture (shorter nonsupine sleep time), and lower AHI during PAP use.

The Korean Society of Cardiac Rehabilitation (KSCR) have recommended standards for establishing cardiac rehabilitation programs in terms of facility, equipment and staff. This is the first time a statement concerning these types of standards has been issued in Korea, and presents the minimal requirements for establishing cardiac rehabilitation programs. Cardiac rehabilitation facilities should contain individual spaces for patient examination, exercise stress testing, monitoring exercise training, patient education, patient preparation, storing medical records, showers and lockers, toilets, and walking tracks. Essential equipment must include at least four sets of aerobic exercise equipment such as treadmills, bicycles, arm ergometers, step machines, and floor mats, and medical equipment such as exercise stress test for ECG with gas analysis, telemetry ECG monitoring systems, sphygmomanometers, stethoscopes, pulse oximeters, glucometers, portable oxygenators, and emergency carts with defibrillators. Hospital staff should include a medical director (a physician with a subspecialty in cardiac rehabilitation), exercise physiologist, nurse specializing in cardiac rehabilitation, exercise specialist, physical therapist, and clinical nutritionist. All should have an expertise in exercise science and be trained in basic life support or advanced cardiac life support. This statement is a recommendation by KSCR and cardiac rehabilitation council of regional cardiocerebrovascular center, and set forth the standards for facilities, equipment, and staff to set up or upgrade cardiac rehabilitation programs in Korea. These recommendations should be developed as a national standard for the establishment of cardiac rehabilitation programs, and adjusted for the current situation of the Korean medical industry through nationwide and long-term research.

BACKGROUND: An earlier index of reperfusion after thrombolytic therapy in patients with acute myocardial infarction is desirable to determine whether additional therapy is necessary to salvage the myocardium. Cardiac troponin-T has been developed as a new myocardial specific marker for myocardial injury and has been used for early assessment of reperfusion therapy. This study was performed to investigate the utility of cardiac troponim-T for assessment of reperfusion therapy using serial serum troponin-T and the rapid assay kit. METHODS: The study was comprised of 70patients(M/F : 64/6, mean age 56+/-2 year) with acute myocardial infarction and reperfusion therapy was initiated within 6 hours after the onset of symtoms. Blood samples for CK and troponin-T were taken before thrombolysis and then 60, 90 munutes, 3, 6, 12, 24, 48, and 72 hours after thrombolysis. We compared successful reperfusion index of troponin-T [successful Reperfusion Index : troponin-T_{90 or 60min-base}> or =0.3 or 0.2ng/ml, Rapid Assay Kit(n=40) : Base(-), 90 or 60min(+)] with the real reperfusion that was assessed by coronary angiogram(TIMI grade 3 at 90 minutes after thrombolysis) or clinical reperfusion index defined as early peak of cardiac enzyme(within 12 hours for CK and within 24 hours for cardiac troponin-T). RESULTS: 1) The cardiac troponin-T and CK activity in patients with successful reperfusion showed early peak within 12 hours after thrombolysis was initiated. 2) Successful reperfusion by angiography or clinical reperfusion index were shown in 64(91%) of 70 patients with thrombolysis. 3) The sensitivity, specificity, positive and negative predictive value, and predictive accuracy for detecting reperfusion using a threshold value of 0.2ng/ml of delta troponin-T at 90 minutes after thrombolysis were 95%, 83%, 98%, 63%, and 96% respectively. 4) The sensitivity, specificity, positive, and negative predictive value, and predictive accuracy of successful reperfusion index using the rapid assay kit at 90 minutes after thrombolysis were 97%, 100%, 100%, 67%, and 97% respectively. CONCLUSIONS: The successful reperfusion index using delta troponin-T> or = 0.2ng/ml and the rapid assay kit at 90 min after thrombolysis are simple and usful for early assessment of reperfusion therapy. Thus bedside monitoring for cardiac troponin-T is now possible to improve the decision making process as to whether rescue angioplasty after thrombolysis is necessary to salvage the myocardium.
