  • The congenital cystic adenomatoid malformation of the lung is a rare disease, and is one of the most common congenital lung diseases which require prompt surgical intervention. The prognosis depends on its tissue type, prompt diagnosis and surgical intervention. The lesion consists of enlarged, variable sized multiple cyst with overgrowth of terminal bronchioles, like hamartoma. This disease can be associated with other vascular anomalies or other congenital defect especially in type II lesion We recently experienced one case of congenital cystic adenomatoid malformation The patient was 2 months old infant who showed respiratory distress without associated anomaly. After right upper lobe lobectomy, the patient was recovered uneventfully.

  • GaAs/AlGaAs quantum-wire (QWR) gain-coupled distributed-feedback (GC-DFB) lasers are fabricated and characterized Constant metalorganic chemical vapor deposition (MOCVD) growth is used to avoid grating overgrowth during the fabrication of DFB structures. Numerical calculation shows large gain anisotropy by optical feedback along the DFB directions near Bragg wavelength. DFB lasing via QWR active gratings is also experimentally achieved.

  • Objective : Sotos Syndrome is characterized by macrocephaly, overgrowth, and developmental delay, and more than 300 patients have been reported worldwide to date. The authors reviewed the clinical characteristics of 8 patients with Sotos Syndrome in Korea for a new understanding and treatment strategies. Methods : The medical records of a total of eight Korean children with Sotos Syndrome were reviewed. All patients underwent developmental checkup, lumbar punctures for measurement of intracranial pressure (ICP), brain and spine magnetic resonance imaging and computerized tomography. Results : All 8 patients showed macrocephaly and the characteristic craniofacial features of Sotos Syndrome. Other clinical characteristics shown were overgrowth (7/8), developmental delay (7/8), congenital heart defect (3/8), flat foot (8/8), scoliosis (4/8), spina bifida (8/8), hydrocephalus (4/8), cavum vergae (3/8), and increased subdural fluid collection (5/8). Mean ICP measured via lumbar puncture was $27.35{\pm}6.25\;cm$ $H_2O$ (range 20 to 36 cm $H_2O$). Two patients received ventriculo-peritoneal shunt, and 1 patient underwent subduro-peritoneal shunt with improvement. Spinal orthosis was applied to 4/5 patients with scoliosis and 4/8 children with flat foot were provided with foot orthosis. Conclusion : In this first Korean study of 8 Sotos Syndrome patients we demonstrated the presence of spina bifida and increased ICP, which had not been previously described. The authors therefore suggest that all patients with Sotos Syndrome should undergo examination for the presence of spina bifida, and that shunt procedures would improve development and alleviate clinical symptoms.

  • Trevor 병이라고도 불리는 편측성 골단 이형성증(dysplasia epiphysealis hemimelica)은 2세에서 14세 연령에서 한측 사지의 내측 또는 외측의 편측 골단부의 연골 이상 발육을 특징으로 하는 소아기의 드문 희귀 질환이다. 국내에서는 술 후 재발한 1례를 포함하여 6례가 보고 되었다. 본 교실에서 경험한 7세 남아는 좌측 슬관절의 통증을 호소하나 슬관절의 변형은 없었다. 단순 방사선 소견상 우슬부 대퇴골 원위부 내과의 골단 내측에 여러 개의 편심성 화골점이 관찰되었고, 자기 공명 영상 소견상 골단부 내측에 불규칙한 화골점 및 비정상적인 연골 비대가 확인되었다. 본 교실에서는 대퇴 내과 골단에 발생한 임상적으로 매우 드문 희귀 질환을 경험하여 자기 공명 영상 소견을 포함하여 문헌 고찰과 함께 보고하는 바이다.

  • Purpose: This study was performed to compare the effects of standardized peristomal skin care (SPSC) and crusting technique (CT) on the peristomal skin of ostomates. SPSC was developed by a consensus among the expert group based on a comprehensive review of the relevant literature and hospital protocols. Methods: A randomized controlled pilot trial with 2 parallel arms was used. A total of 81 ostomates, who were recruited from a tertiary hospital, completed the baseline, 1-month, 2-month, and 3-month follow-up (SPSC group, n=45; CT group, n=36). SPSC consisted of water cleansing and direct application of ostomy appliances. CT involved crusting hydrocolloid powder and patting with water sponge or protective barrier liquid film. The outcomes of the study were assessed by skin problems, such as discoloration, erosion and tissue overgrowth; the domains of the evaluation tool used in examining the peristomal skin. A generalized estimating equation model was used to examine the effects according to time and group. Results: In both SPSC and CT groups, the likelihood of occurrence of discoloration (OR, 1.99; 95% CI, 1.61-2.46), erosion (OR, 1.87; 95% CI, 1.55-2.25) and tissue enlargement (OR, 1.94; 95% CI, 1.36-2.77) increased with time. There was no significant difference in discoloration between the groups, whereas the probability of erosion (OR, 0.38; 95% CI, 0.16-0.89) and tissue overgrowth (OR, 0.09; 95% CI, 0.02-0.55) was lower in the SPSC group than in CT group. Conclusion: SPSC was sufficient in preventing peristomal skin problems of ostomates compared to the CT.

  • Seed crystal 로 bare (0001) 사파이어 기판을 사용하여 hydride vapor Phase epitaxy (HVPE)법을 이용하여 free-standing GaN 단결정기판을 성장시켰다. 일정한 두께의 GaN막을 성장한 후 사파이어 기판을 mechanical polishing 작업으로 제거하여 두께 200 ㎛, 10×10 ㎛ 크기의 free-standing GaN 기판을 얻을 수 있었으며, 성장 전 GaCl 전처리를 수행함으로써 crack이 없는 기판을 제작할 수 있었다. 이렇게 제작된 free-standing GaN 기판의 특성을 SiO/sub 2/ patterned sapphire위에 LEO (Lateral Epitaxial Overgrowth) 방법으로 성장된GaN박막과 double crystal x-ray diffraction (DC-XRD), cathode-luminescence (CL) 및 photoluminescence (PL) 방법으로 특성을 비교하였다.
