Primary aldosteronism is a syndrome characterized by hypertension, hypokalemia, suppressed plasma renin activity, and elevated serum aldosterone levels. Conn first described it 1955 in association with adrenal cortical adenoma(Conn's syndrome). Today, it can be divided into at least six distinctive sub-groups. The diagnosis of primary aldosteronism is usually suspected when the patient presents with poorly controlled hypertension with hypokalemia. The main issues in the evaluation of primary aldosteronism are to differentiate an adenoma from hyperplasia and to localize the adenoma. Basic hormonal studies and computed tomographic(CT) scanning can be used effectively for that differentiation. An adenoma is one of a few potentially curable forms of hypertension, and it is best treated by removing the adrenal tumor. We experienced a case of a typical adrenal adenoma. The patient was a 37-year-old male who had experienced in both his legs over a period of several days a weakness due to hypokalemia. He was diagnosed using basic hormonal studies and adrenal CT scanning. After, he received laparoscopic adrenalectomy and was discharged with improved condition.

교정치료에서 원하는 치아이동을 위해서는 안정된 고정원이 필요한데 티타늄 미니스크류가 매식과 제거가 쉽고, 구강 내 여러 부위에서 적용이 가능하고, 환자가 느끼는 불편감이나 비용적인 부담이 적고, 제거 후에 치유가 빠르게 진행될 수 있는 등의 장점이 있어 최근에 교정적 고정원으로 사용되기 시작하였다. 티타늄 미니스크류를 교정적 고정원으로 사용한 임상 예들이 여러 편 발표되었는데 미니스크류의 이완이 가장 큰 실패의 원인으로 보고되고 있다. 그러나 지금까지 보고된 논문들에서 교정적 고정원으로 안정성을 줄 수 있는 스크류의 식립 길이에 관한 연구가 없는 상태이다. 교정적 고정원으로 미니스크류를 효과적으로 사용하기 위해서는 식립 부위에 따른 골구조와 골밀도 차이를 고려한 식립 길이에 관한 기준이 필요하다. 이에 본 연구에서는 성견의 상악골과 하악골에서 직경 2mm 티타늄 미니스크류를 다양한 길이로 식립하고 교정력을 적용한 후 그 안정성을 평가하여 교정적 고정원으로 사용될 수 있는 미니스크류의 식립 길이를 결정하고자 하였다. 미니스크류가 상악에서는 6mm이상, 하악에서는 4mm 이상이 골 내에 식립될 때 8주 동안 200g의 교정력에 동요도나 위치변화를 보이지 않았다. 식립 부위로는 부착치은 부위 치근 사이에 식립될 때 구강청결이 유지되고 미니스크류 주변 치은조직에 자극을 주지 않아 정상적인 조직으로 유지 될 수 있었다. 또한 교정력 적용 8주 후 치근단 방사선 사진검사에서 스크류 주변 치근 흡수나 치조골 흡수, 치주 인대 손상이 관찰되지 않았다. 따라서 상 ㆍ 하악 골밀도와 골구조의 차이를 고려하여 미니스크류의 골내 식립 길이를 적절히 조절함으로써 교정적 고정원으로 티타늄 미니스크류가 효과적으로 사용될 수 있다고 생각된다. Titanium miniscrews are being used increasingly as an anchorage for tooth movement, because they are easy to place and to remove, increase the number of sites available, give minimum strain to patients regarding surgical procedures, and offer uneventful healing after removal. The use of titanium miniscrews as an orthodontic anchorage has been reported in clinical case reports, but clinicians hove experienced screw loosening when using such screws. To our knowledge, there are no published reports evaluating the stability of miniscrews. Information about the length of miniscrews used in relation to the location is of some importance, as stability will vary depending on bone quality. The purpose of this study was to evaluate a variety of lengths of miniscrews (diameter: 2mm) which were inserted in maxilla or mandible and to demonstrate in a dog moedl which miniscrew provides fundamental stability in the jaws. 10 mm long miniscrews in the maxilla and 8mm long miniscrews in the mandible showed no clinical mobility and retained their position throughout an 8 weeks force (200g) application. The mucosal condition around the screws was healthy in cases in which miniscrews were inserted in the alveolar bone between the roots and the head of the screws emerged into the attached gingiva. When the force application was terminated, radiographic analysis revealed neither root resorption nor periodontal pathology around the miniscrews that remained stable during the entire treatment period. This study suggests that if titanium miniscrews with adequate length are properly used depending on the location, they provide sufficient stability for orthodontic anchorage.

This study was performed to assess the radiopacity of a variety of root canal sealers according to the Specification concerning root canal sealers. Ten materials including Tubli-Seal™, Kerr Pulp Canal Sealer™, AH 26^(R), AH plus^(R), AH plus jet™, Ad seal™, Sealapex™, NOGENOU™, ZOB seal™, Epiphany™, and dentin were evaluated in this study. In the first part. densitometric reading of an each step of aluminum step wedge on occlusal film was performed at different voltage and exposure time. In the second part, ten specimens were radiographed simultaneously with an aluminum step wedges on the occlusal films under decided condition. The mean radiographic density values of the materials were transformed into radiopacity expressed equivalent thickness of aluminum (mm Al). The following results were obtained 1 Among the various conditions, the appropriate voltage and exposure time that meet the requirement density was 60 kVp at 0.2 s 2 All of the materials had greater radiopacity than 3 mm Al requirement of ANSI/ADA specification No. 57 (2000) and ISO No. 6876 (2001) standards. 3 The radiopacity of materials increased as thickness of materials increased. 4 The mm Al value of each specimen at 1mm in thickness has a significant difference in the statistics. It suggests that root canal sealers have a sufficient radiopacity that meet the requirement. 다양한 근관전색제는 방사선 사진상 주위 해부학적 구조와 구별될 만한 방사선 불투과성을 나타내야 한다 따라서 이런 물질들이 근관에 충전될 때의 방사선 불투과성 정도를 평가해야 할 필요성이 대두되고 있다. 본 실험에서는 다양한 근관전색제들의 방사선 불투과성을 평가하고자, 방사선 노출조건에 따른 aluminium step wedge에 대한 광학 밀도를 알아보고, 그 중 적절한 노출조건을 선택하여 수종의 근관 전색재의 방사선 불투과성 정도를 알루미늄 두께로 환산하여 비교해 보고자 한다. 방사선 불투과성의 기준을 위해 11개의 step으로 구성된 aluminum step wedge을 사용하여, 60kVP, 70kVp관전압 상태에서 각각 0.2, 0.3, 0.4초 그리고 0.2, 0.3, 0.33초의 꼭 노출시간으로 교합필름상에서 방사선 촬영후 적절한 노출 조건을 구하였다. 직경 5mm 각각의 두께 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 mm인 10종 (Tubli-Seal™, Kerr pulp Canal Sealer™, AH26^(R), AHplus^(R), AH plus jet starter kit™, Ad seal™, Sealapex™, Nogenol root canal sealer™, ZOB seal™, Epiphany™)의 근관전색재 시편을 각 재료와 두께당 10개씩 제작한 후, 동일한 두께의 상아질 시편, aluminum step wedge와 함께 정해진 노출시간에 따라 방사선 촬영을 하였다. 모든 필름은 자동현상기로 현상하였다. 시편의 방사선 흑화도를 densitometer로 5회 반복 측정 후, 평균값을 구하여 알루미눔 두께로 환산하였다.얻어진 정보를 분석하여 다음의 결과를 얻었다. 1 관전압 60 kVp에서 노출시간 0.2, 0.3, 0.4초, 70 kVp에서 0.2, 0.3, 0.33초로 변화를 주어 방사선 촬영을 하였을 때 흑화도가 ISO No. 6876 규격에 가장 적합한 것은 60 kVP, 0.2초 일 경우였다. 2 측정된 근관 전색제의 방사선 불투과성은 2.29 mm Al (N0GEN0L)로부터 13.69 mm Al (AH Plus jet)까지 다양하게 나타났으나, 모두 ANSI/ADA specification (2000) 또는 ISO No. 6876 (2001) 규격이 제시한 최소한 3mm Al 이상의 방사선 불투과성을 지녀야 한다는 기준에 적합하였다. 3 재료의 두께가 증가할수록 방사선 불투과성은 증가하지만, 정비례하지는 않았다. 4 각 실험재료의 1 mm 두께의 시편에 대한 mm Al값들은 통계적으로 유의한 차이가 있었다. 이상의 결과는 본 실험에 사용된 수종의 근관 전색재는 모든 규격에 적합한 방사선 불투과성을 가지고 있음을 시사한다.
