The ectopic ureterocele is uncommon developmental abnormality of the urinary tract. Most commonly associated anomaly of the upper urinary tract in the ectopic ureterocele is duplex ureter which is often complicated with hydronephrosis. We report an unusual case of the giant hydronephrosis with ectopic ureterocele in bilateral complete duplicated ureters in 17 months old boy, and the literatures were reviewed.

PURPOSE: To assess the utility of shoulder MRI by using ROC (receiver operating characteristic) curve in theevaluation of rotator cuff tear, anterior labral tear, superior labral tear and Hill-Sachs Lesion. MATERIALS AND METHODS: We evaluated 38 arthroscopically confirmed patients who had undergone shoulder MRI. According to thesignal intensity of the rotator cuff, as seen on T2 and proton density imaging, a five-stage grading system wasdevised. Labral tears were graded according to the separation of the labium; this was based on gleaned,morphologic and signal intensity changes of the labrum : six grades of anterior labral tear and three grades ofsuperior labral tear. Hill-sachs lesion was also classified into four grades according to morphologic and signalchanges of the humeral head. These findings were reviewed by two musculoskeletal radiologists and ROC curves andareas under the curve (Az) was abtained. RESULTS: The ratio of area under the curve of rotator cuff tear,anterior labral tear, superior labral tear and Hill-Sachs lesion were 82.4%, 88.%%, 62.4% and 91.3%, respectively. CONCLUSION: The Accuracy of shoulder MRI using ROC curve was relatively high in rotator cuff tear, anteriorlabral tear and Hill-Sachs lesion, but low in superior labral tear.

We report a 36-year-old male with the bilateral visual field defect following LASIK was observed. Preoperatively, patient had high myopia(right. -7.25 0.75x18, left. -7.5-0.5x12), normal intraocular pressure(IOP)(right/left: 16/14 mmHg), normal visual field(Humphrey 30-2 visual field)and revealed the tilted discs with symetric optic nerve head cupping(cup-to-disc ratio, 0.70), parapapillary atrophy. Bilateral LASIK keratorefractive surgery was on the same day and intraoperative complication was not noted. After the first operative visit day, examination revealed uncorreted visual acuity right 0.8 and left 0.6 but scotoma was reported. Three months later, Humphrey 30-2 visual field revealed a near-superior altitudinal defect in the right eye and nasal side visual field defect in the left eye. Best corrected visual acuity was 1.0 in the right eye, 0.8 in the left eye. Repeated visual fields over a 11-month period postoperatively showed stability of the defect, with IOP of 12 mmHg to 15 mmHg in each eye. We considered LASIK uses a microkeratome vaccum ring to make a corneal flap, transient elevation of IOP alters the microcirculation of optic nerve head and may have precipitated visual field defect.

The chondrogenic potential of free autogenous periosteal grafts for osteochondral defects was investigated at the Department of Orthopaedic Surgery, Yonsei University, Wonju College of Medicine. Five millimeter diameter of circular full-thickness defects were made in patellar groove of both femur in 64 adolescent rabbits and the rectangular periostei, prepared from the proximal tibiae, were placed over the defects of patellar groove and sutured(cambium layer, facing joint surface) and the rabbits were allowed to move actively. A serial gross and histologic examinations of neochondrogenesis were done during 8 weeks. The results were as follows. l. At 2 weeks after operation, neochondrogenesis was hardly seen either in the graft group or in the control group. The defects were partially filled with some fibrous tissue. 2. After 6 weeks of operation, all defects in the graft group(postop 6 weeks and 8 weeks) were filled with hyaline cartilage cells but only 38% (postop 6 weeks) and 44% (postop 8 weeks) of the control group were filled with hyaline cartilage cells. 3. The cartilages, formed at 6 and 8 weeks, were more mature and better than those formed at 4 weeks. 4. The newly formed hyaline cartilage of the graft group filled the defect earlier and were better than those of the control group. 5. The chondrocytes in the newly formed tissue were originated from the cambium layer of periosteal grafts. 6. Free autogenous periosteal grafts can repair a full-thickness defect in a joint surface by producing tissue that resembles articular cartilage grossly and histologically.

OBJECTIVES: Tree pollen causes allergic rhinitis and asthma. We investigated children who diagnosed as rhinitis or asthma, living in Busan, for tree allergen sensitization, component allergen, oral allergy syndrome, and the relationship between pollen counts and allergen sensitization.METHODS: Pollen were collected in Busan, from January 1 to December 31, 2017, using a Rotorod sampler and enumerated using a microscope. We conducted a study of children with rhinitis or asthma at Busan St. Mary's Hospital in 2017, administered an ISAAC questionnaire, and an oral allergy syndrome survey. Serum specific Ig E tests were performed.RESULTS: Among the 57 patients, the mean age was 9.3 years. The pollen counts in decreasing order were as follows: pine, alder, oak, juniper, beech, ginkgo, and birch. For sensitization, birch and alder 35.1%, Japanese cedar 19.3%, juniper 17.5%, pine 10.5%, and Japanese cypress 8.2%. The component Ig E was tested in 27 patients. Bet v 1 had a high correlation with birch, alder, and peach. Bet v 2 showed a statistically significant correlation with all tree pollen except cypress. Bet v 4 did not have any apparent correlation. Bet v 6 had the same pattern as Bet v 2, but correlation coefficient was higher than that of Bet v 2. Oral allergy syndrome was noted in 7 patients, including peach, peanut, apple, tomato, kiwi, and sesame.CONCLUSIONS: Alder and juniper are clinically important tree pollens in Busan. These pollens cause sensitization to birch and Japanese cedar by cross-reaction.

PURPOSE: Even though Malassezia yeast may play an important role in the exacerbation of atopic dermatitis (AD), only a few studies of Malassezia infection have been conducted in children with AD. Thus, we compared each of clinical findings, including the severity of head and neck dermatitis and laboratory results depending on specific IgE against Malassezia furfur. METHODS: This cross-sectional study was carried out on 121 children aged 3 months to 18 years between April and July of 2014. Retrospective data was collected using the medical records, and patients were divided into 2 groups according to the presence of Malassezia sensitization. RESULTS: Specific IgE against Malassezia (group 1) was observed in 28 of all patients (23.1%). Group 1 children were at an older age (9.1+/-6.9 vs. 2.1+/-3.7, P<0.001). Group 1 children had a higher SCORing Atopic Dermatitis (SCORAD) index (46.4+/-21.0 ng/mL vs. 37.2+/-13.4 ng/mL, P=0.001), and total IgE (1,324.2+/-1,166.0 IU/mL vs. 209.5+/-532.5 IU/mL, P<0.001) compared to group 2 children (Malassezia-). In the group 1, the correlation between the Malassezia-specific IgE and 25-hydroxyvitamin D3 was negatively weak (r=-0.106) and not statistically significant (P=0.246). Furthermore, Malassezia-specific IgE and the SCORAD index (r=0.281, P=0.002) or total IgE (r=0.380, P<0.001) were positively correlated. CONCLUSION: The results of this study suggest that specific IgE against M. furfur may be helpful in assessing the severity of prepubertal children and early adolescents with AD involving the head and neck.

Infection-induced acute hepatitis complicated with acute pancreatitis is associated with hepatitis A virus, hepatitis B virus or hepatitis E virus. Although rare, Epstein-Barr virus (EBV) infection should be considered also in the differential diagnosis if the patient has acute hepatitis combined with pancreatitis. We report a case of EBV infection with cholestatic hepatitis and pancreatitis with review of literature. An 11-year-old female was admitted due to 1-day history of abdominal pain and vomiting without any clinical symptoms of infectious mononucleosis. Diagnosis of reactivated EBV infection was made by the positive result of viral capsid antigen (VCA) IgM, VCA IgG, Epstein-Barr nuclear antigen and heterophile antibody test. We performed serologic tests and magnetic resonance cholangiopancreatography to exclude other viral or bacterial infection, autoimmune disorder, and structural problems. The patient's symptoms recovered rapidly and blood chemistry returned to normal with conservative treatment similar to previously reported cases.
