Ectopic lacrimal gland denotes a lacrimal gland which is located anywhere other than its normal site, lacrimal fossa, and it can occur in places like conjunctiva, cornea, lid, nasal mucosa, and orbit. It is a rare congenital anomaly and needs to be differentiated form other tumors. The literature contains few reports of ectopic lacrimal gland. We experienced a case of a 28-year-old Korean man who presented with an ectopic lacrimal gland with duct at temporal aspect of bulbar conjunctiva. The glandular tissue was excised and was histopathologically confirmed as such. We report it with reviews of the literature concerned.

Amblyopia and strabismus are common in eyes of prematurity and the need for early detection of amblyopia and amblyogenic factors is widely recognized. So, we performed refraction in premature infants at the 6 months of age to evaluate the incidence and degree of myopia and the changes of refractive errors according to the development, disease course and photocoagulation therapy of retinopathy of prematurity[ROP]. It is the purpose of this study to evaluate the effectiveness of MTI[medical Technology, Inc]photoscreener by comparing the sensitivity and specificity between refractive errors determined by manifest photorefraction and cycloplegic photorefraction in 6-month-old premature infants in Sung-Ae General Hospital. Pass or fail screening data from photograph of 32 non-dilated and dilated premature infant were calculated by two masked observers, compared with the results of cycloplegic retinoscopy, and the statical analysis was carried out. In the cases of cycloplegic photorefraction, Ten eyes of myopia, 4 eyes of emetropia, and 50 eyes of hyperopia were found, and 21 eyes of astigmatism above 1.5D were also detected. Overall statistical analysis of sensitivity and specificity rate were 71.7% and 69.5%in manifest photorefraction, 87.5% and of 75%in cycloplegic photorefraction, respectively. In non-cycloplegic photorefraction, sensitivity of myopia and hyperopia were 92.8%, 65%, but in cycloplegic photorefraction, sensitivity of myopia and hyperopia were 75%, 100%, respectively. The outcomes of our study suggest that MTI photoscreener in cycloplegic photorefraction was more reliable than non-cycloplegic photorefraction. Myopia under 1D turned to hyperopia in cycloplegic photorefraction, so the sensitivity of that was not to be reliable, but the sensitivity of hyperopia was high. Thus, the authors can readily recommand this cycloplegic photorefraction in uncooperable infants to evalute the refractive error conveniently.

BACKGROUND: The direct relationship between minor plaque prolapsed within stents and late in-stent restenosis is unknown. Therefore, we evaluated the impact of minor plaque prolapse on late angiographic in-stent restenosis. MATERIALS AND METHODS: Intravascular ultrasound (IVUS) guided single-coronary stenting was successfully performed in 384 consecutive patients with 407 native coronary lesions. Six-month follow-up angiogram was performed in 315 patients (82.0%) with 334 lesions (82.1%). Minor plaque prolapsed within stent occurred in 75 of 334 lesions (22.5%). Results were evaluated using angiographic and IVUS methodology. RESULTS: The development of minor plaque prolapse was significantly associated with infarct-related artery (p=.000) and smaller pre-intervention minimal lumen diameter (p=.001). The overall angiographic restenosis rate was 23.1% (77/ 334); 21.3% (16/75) in the lesions with plaque prolapse vs. 23.6% (61/259) in the lesions without plaque prolapse (p=.806). CONCLUSION: Minor plaque prolapsed within stents might not be associated with late angiographic in-stent restenosis.

BACKGROUND: The impacts of minor non-flow limiting dissections at the edge of stents on the late clinical outcomes are unknown. Therefore, we evaluated the influences of minor edge dissections on late angiographic in-stent restenosis. SUBJECTS & METHODS: Intravascular ultrasound (IVUS) guided single coronary stenting was successfully performed in 390 consecutive patients with 420 native coronary lesions. Six-month follow-up angiogram was performed in 327 patients (83.9%) with 348 lesions (82.9%). RESULTS: Proximal or distal minor edge dissections were observed in 67 of 348 lesions (19.3%) (proximal in 26 lesions, distal in 37 and both in 4). In distal reference segments, lumen areas and diameters were significantly smaller in the lesions with minor edge dissection (p=.037 and 0.025, respectively). The overall angiographic restenosis rate was 26.2% (91/ 348); 29.9% (20/67) in the lesions with minor edge dissections vs. 25.3% (71/281) in the lesions without minor edge dissections (p=.540). All minor dissections disappeared and were completely healed at follow-up IVUS study. CONCLUSION: Minor non-flow limiting dissections at the edge of stents might not be associated with the development of late angiographic in-stent restenosis.

BACKGROUND AND OBJECTIVES: Recent advances in trans-radial coronary intervention (TRI) have shown a reduction in patient's morbidity. However, the role of TRI for a chronic total occlusion (CTO) is not well established. The aim of this study was to assess the safety and feasibility of TRI for a CTO. SUBJECTS AND METHODS: Sixty-three successive CTO lesions of more than 2 months duration were prospectively included in this registry between April 2002 and November 2003. Guiding catheters with strong back-up, stiff guide wires and supportive infusion catheters were actively used. The angiographic and procedural characteristics were prospectively evaluated. RESULTS: There were 45 male and 18 female patients, with a mean age of 59.8+/-9.5 years. The most common clinical diagnosis was stable angina (95.2%). The mean duration of the occlusions was 10.3+/-1.6 months. Procedural success was achieved in 53 lesions (84.1%). No cases were crossed over to transfemoral procedure. The most common cause of procedural failure was guide wire passage failure (7 lesions). The mean duration of occlusions was significantly longer in the failure group (7.5+/-1.1 versus 24.8+/-6.5 months, p<0.001). Bridging collateral vessels, long occlusions, calcification at lesion sites, a side branch at the occlusion site and blunt entry morphology were also statistically significant predictors for procedural failure. Procedure-related complications were noted in 6 patients (9.8%), which included coronary perforations (3.3%), severe dissections (3.3%), arrhythmia (1.6%) and branch artery occlusion (1.6%). No patients suffered from local complications, such as hematoma or radial artery occlusion. CONCLUSION: TRI for a CTO seems to be safe and feasible, with acceptable success and complication rates.

BACKGROUND AND OBJECTIVES: Biochemical markers are useful for the prediction of cardiac events in patients with acute coronary syndrome (ACS). The N-terminal fragment of the BNP prohormone (NT-proBNP), which is synthesized by cardiac ventricles in response to increased wall stress, may be a prognostic marker in ACS. The relation between the NT-pro BNP levels on admission and major adverse cardiovascular events (MACEs) were assessed in a cohort of patients with ACS. SUBJECTS AND METHODS: Between October 2002 and April 2004, blood samples for the determination of NT-proBNP level were obtained on admission from 78 patients with ST-elevation myocardial infarction (STEMI), 32 with non-ST elevation MI(NSTEMI) and 66 with unstable angina (UA). Patients were followed concerning MACEs (death, MI, heart failure, stroke and revascularization) for a median of 7 months in median. RESULTS: 22 patients (13%) had events. The mean NT-proBNP level was significantly lower in the event-free survivors than in those with events (1342+/-1598 versus 6129+/-6522 pg/mL, p<0.0001). The optimal cut-off value of the NT-proBNP level using a receiver-operating-characteristic curve was 1445 pg/mL. The unadjusted risk ratio of patients with an NT-proBNP level greater than the threshold was 7.0 (95% confidence interval, 2.6 to 19.0). In a multivariate Cox regression model, including clinical background factors and other biochemical markers, the NT-proBNP level was the most powerful indicator of MACEs (risk ratio, 8.0 [95% confidence interval, 1.7 to 37.1]). The coronary angiographic Gensini score was also a predictor of prognosis in ACS (risk ratio, 3.8 [95% confidence interval, 1.0 to 14.0]). CONCLUSION: A single measurement of the NT-proBNP level on admission appears to be useful as a prognostic factor in the prediction of MACEs in patients after ACS.

OBJECTIVES: The aim of this multicenter registry study was to investigate the effectiveness of ventilation tube insertion and the microbiology of otitis media with effusion (OME) in children. This part I study was conducted to evaluate the microbiological profile of children with OME who needed ventilation tube insertion. METHODS: Patients < 15 years old who were diagnosed as having OME and received ventilation tube insertion were prospectively enrolled in 16 tertiary hospitals from June 2014 to December 2016. After excluding patients with missing data, the data of 397 patients were analyzed among a total of 433 enrolled patients. The clinical symptoms, findings of the tympanic membrane, hearing level, and microbiological findings were collected. RESULTS: In 103 patients (25.9%), antibiotics were used within 3 weeks before surgery. Ventilation tube insertion was performed in a total of 710 ears (626 in both ears in 313 patients, 55 in the left ear only, and 29 in the right ear only). Culture of middle ear effusion was done in at least one ear in 221 patients (55.7%), and in a total of 346 ears. Only 46 ears (13.3%) showed positive results in middle ear effusion culture. Haemophilus influenzae (17.3%, followed by coagulase-negative Staphylococcus and Staphylococcus auricularis) was the most common bacteria detected. CONCLUSION: H. influenzae was the most commonly found bacteria in middle ear effusion. Relatively low rates of culture positivity were noted in middle ear effusion of patients with OME in Korea.

Objectives: . The impacts of ventilation tube (VT) type and effusion composition on the VT extrusion rate and complications in children with otitis media remain unclear. This part II study evaluated the factors affecting the extrusion rate, recurrence rate, and complications of VT insertion. Methods: . A prospective study was conducted between June 2014 and December 2016 (the EVENT study [analysis of the effectiveness of ventilation tube insertion in pediatric patients with chronic otitis media]), with follow-up data collected until the end of 2017. Patients aged <15 years diagnosed with otitis media with effusion who received VT insertion were recruited at 15 tertiary hospitals. The primary outcomes were time to extrusion of VT, time to effusion recurrence, and complications. Results: . Data from 401 patients were analyzed. After excluding the results of long-lasting tubes (Paparella type II and T-tubes), silicone tubes (Paparella type I) exhibited a significantly longer extended time to extrusion (mean, 400 days) than titanium tubes (collar-button-type 1.0 mm: mean, 312 days; P<0.001). VT material (hazard ratio [HR], 2.117, 95% confidence interval [CI], 1.254–3.572; P=0.005), age (HR, 3.949; 95% CI, 1.239–12.590; P=0.02), and effusion composition (P=0.005) were significantly associated with the time to recurrence of middle ear effusion. Ears with purulent (mean, 567 days) and glue-like (mean, 588 days) effusions exhibited a shorter time to recurrence than ears with serous (mean, 846 days) or mucoid (mean, 925 days) effusions. The revision VT rates during follow-up were 3.5%, 15.5%, 10.4%, and 38.9% in ears with serous, mucoid, glue-like, and purulent effusions, respectively (P<0.001). The revision surgery rates were higher among patients aged <7 years than among those aged ≥7 years. Conclusion . Silicone tubes (Paparella type I) were less prone to early extrusion than titanium 1.0 mm tubes. VT type, patient age, and effusion composition affected the time to recurrence of effusion.
