  • Temporomandibular joint cysts usually occur between the second and fourth decade of life. There is a female predominance to male of approximately 3 to 1. The patients complain of swelling, pain and sometimes decreased mouth opening. Synovial cysts of the temporomandibular joint seem to develop by an increase of intraarticular pressure due to trauma or inflammation which causes capsular herniation. However, if inflammatory synovial cysts develop by an increase of synovial fluid into inflammation tissue in the capsule without capsular herniation, a differential diagnosis should include synovial chondromatosis and synovitis. This is a case report of a synovial cyst developed in a capsule of the temporomandibular joint.

  • Choledochal cyst is rare in the western countries, but common in oriental countries. Complicatioins include ascending cholangitis, recurrent pancreatities, progressive biliary cirrhosis, portal hypertension, stone formation and later malignant transformation. Bile peritonitis secondary to rupture is one of the rarest complications, with an incidence of 1.8 % to 18 %. The anomalous arrangement of the pancreatobiliary ductal system with a long common channel may cause inflammation leading to perforation of the cyst. The authors found 4 cases (14.2 %) of bile peritonitis among 28 cases of choledochal cyst treated from Jan. 1983 to Jan. 1998. The patients ages ranged from 6 months to 3 years and three were female. The perforation sites were located on the common bile duct at its junction with the cystic duct in 2 cases, the distal cyst wall in 1 case and the left hepatic duct at its junction with cyst in 1 case. The types of choledochal cysts by Todani's classification were Type IVa in 3 cases and type I in 1 case. By the new Komi's classification utilizing operative cholangiogram there were 2 cases of Type Ia, 1 case of type IIb and 1 case of type III. One stage cyst excision and hepaticojejunostomy(Roux-en Y type) was done in 3 cases, and two staged operation in 1 case. All patients had an uneventful course postoperatively. The average day of discharge was 9.8th postoperatively. In conclusion, primary excision of the choledochal cyst and biliary reconstruction is a safe and effective treatment of ruptured choledochal cyst in infants.

  • 탈회냉동건조골 (DFDBA)과 ePTFE막을 사용한 경우와 ePTFE만을 사용한 경우의 조직유도 재생술의 효과를 관찰하였다 . 12명의 환자에서 12개의 골내낭결손부(한 환자당 하나의 결손부)를 통상적인 치주수술 시행한 경우를 대조군(GFS)으로 , 12명의 환자에서 12개의 결손부는 ePTFE(GTR)막 만으로 , 또 다른 환자의 12개결손부는 ePTFE+DFDBA로 시행하였다. 창상안정과 감염방지를 강조한 술후계획이 사용되었다. 술후 6개월째 임상적 치유상태를 평가 하였다. 대조군에서 치주낭깊이, 부착수준, 탐침골깊이, 치은퇴축의 각각의 평균치는 $3.4{\pm}1.3mm$, $2.0{\pm}1.2mm$, $1.3{\pm}2.0mm$, $-1.7{\pm}0.8mm$, GTR 군에서는 $4.3{\pm}l.3mm$, $3.1{\pm}1.5mm$, $4.2{\pm}2.2mm$, $-11{\pm}1.4mm$ 그리고 GTR+DFDBA 군에서는 $3.4{\pm}2.1mm$, $2.4{\pm}1.9mm$, $2.6{\pm}1.6mm$, $-1.2{\pm}1.7mm$를 보였다. 대조군과 GTR+DFDBA 군의 술전 평균 치주낭깊이는 각각 $6.9{\pm}1.1$, $7.4{\pm}1.2$, $7.0{\pm}2.0mm$였다. GTR, GTR+DFDBA군에서는 뚜렸한 치주낭감소와 부착획득을 보였다(P<0.01). GTR, GTR+DFDBA 에서는 대조군에 비해 탐침골수준의 뚜렷한 향상을 보였으나(P<0.001), GTR 과 GTR+DFDBA 사이에는 뚜렷한 차이가 없었다. 이 실험결과로 골내낭 결손부에서 GTR과 GTR+DFDBA의 사용은 골형성을 제외한 임상결과 에서 대조군과 유사한 결과를 보였다.

  • The purpose of this study was to evaluate the eruption patterns of mandibular premolars associated with dentigerous cysts after marsupialization regarding the depth, angulation and root development of impacted teeth. Spontaneous eruption was found in 93% of mandibular premolars after marsupialization. Eruption speed and rate of angulation change were greater in mandibular premolars associated with a cyst than those on the non-cyst side. The group with less matured roots tended to have greater eruption speed and angulation change. The eruption speed and angulation change declined rapidly during the first 6 months after marsupialization. Based on the results of this study, it might be possible to predict the eruption pattern of mandibular premolars associated with a cyst after marsupialization, which would be useful for treatment planning.

  • In this paper, the methodology applied to the improvement of stress analyses is extended to free vibration and buckling analyses. The essence of the methodology is the Saint-Venant's principle that is applicable to beam and plate models. The principle allows one to dimensionally reduce three-dimensional elasticity problems. Thus the methodology can be employed to vibration and buckling as well as stress analysis. First, the principle is briefly revisited, and then the formations of classical beam theories are presented. To improve the predictions, the perturbed terms (unknowns) are introduced together with the warping functions that are calculated by stress equilibrium equations. The unknowns are then calculated by applying the equivalence of stress resultants (i.e., Saint-Venant's principle). As numerical examples, cantilever and simply supported beams are analytically solved. The results obtained are compared with those of the classical beam theories. It is shown that the methodology can be used to improve the predictions without introducing shear correction factors.

  • A 67-year-old male with a 6-year history of emphysema was admitted with severe dyspnea. On chest computed tomographic scan, a newly developed large bulla was detected in right lower hemithorax. This bulla was sucessfully managed by intracavitary drainage [modified Monaldi procedure] with symptomatic improvement. We report this case with review of the literature.
