악안면 형성과정의 이상으로 인한 구조적 결함상태로 정의되어지는 악안면 기형(maxill-ofacial ogtal malformation)은 사고나 기능적(funct-ional) 장애로 인해 후천적으로 생길 수도 있으나 유전적 원인 등으로 인한 선천적 경우도 많다. 특히 후자의 경우에는 여러 증후군과 결합되어 나타나는 수가 많다. 치과의사는 치아이상이나 기능적 이상으로 인한 기형의 치료 및 예방을 담당할 책임이 있으며, 더욱이 새로운 진료실에서 직접 대면할 수 있는 최초의 의사가 될 수 있다는 점에서 특별한 기형외에도 전반적인 증후군에 대한 지식을 갖는 것이 중요하다. 악안면 기형환자에게는 전반적 검사가 필수적이며 방사선 분석, 치아모형 분석 등 다양한 분석이 필요하나, 여기에서는 주로 병력 청취나 시진을 통한 검사에 중점을 두어 서술하고자 한다.

Purpose: Differential diagnosis between arteriovenous (AVMs) aud non-arteriovenous malformations (nAVMs) is important in patients with congenital vascular malformations, because AVMs can cause hemodynamic alteration and require immediate treatment. We investigated whether transarterial lung perfusion scintigraphy (TLPS) was useful for the diagnosis and post-therapeutic evaluation of AVMs in extremities. Materials and Methods: Fifty-seven patients (M:F=26:31, $21{\pm}13$ yr, 9 upper and 48 lower extremities) suspected of congenital vascular malformations in extremities underwent TLPS using $^{99m}Tc-MAA$ before embolization/sclerotherapy. Dose-corrected shunt fraction (SF) was calculated from time-activity curve of the lung. Final diagnosis of AVMs was determined by angiography. in patients with AVMs, follow-up TLPS was done for post-therapeutic evaluation. Results: Sixteen patients (8 upper and 8 lower extremities) had AVMs, while the remaining 41 had nAVMs (1 upper and 40 lower extremities). The mean SF of AVMs on TLPS was significantly higher than that of nAVMs ($66.4{\pm}25.8%\;vs.\;2.8{\pm}4.3%$), p=0.003). The sensitivity, specificity, and accuracy of TLPS (cut-off of SF = 20.0%) in diagnosis of AVMs before treatment were 93.8% (15/16), 100% (41/41) and 98.2% (56/57), respectively. The follow-up TLPS and angiography for post-therapeutic evaluation showed concordant results in 13 of 16 patients (81.3%) with AVMs. The mean SF of TLPS was significantly decreased after embolization/sclerotherapy ($69.5{\pm}24.0%\;vs.\;41.0{\pm}34.7%$, p=0.01). Conclusion: TLPS provides hemodynamic information of AVMs in extremities semiquantitatively. Furthermore, the results of TLPS showed a high concordance rate with angiographic findings. Therefore, TLPS is useful for the diagnosis and post-therapeutic evaluation of AVMs in extremities.

The results investigated of the effect of light, pH, and nutrients in vitro and the levels of fertilizer(P,K and Ca) in vivo in order to find out the effect of environmental factors in forming an appressorium of Colletotrichum truncatum were as follows; The ratio of appressorium formation promoted more in a light treatment than in a dark treatment according to investigation after three and six hours passed away. But after the period, the ratio of appressorium formation promoted highly in both treatments. Reasonable pH of appressorium formation was pH 6-pH 8. The ratio of appressorium formation was the most favorable at none nutrient level in every treatment of C-source and N-source, and suppressed in a high concentration of C-source and N-source. But according as the time passed away, the ratio of appressorium formation promoted in C-source and N-source. When their quantities were increased in P and K treatments, the ratio of appressorium formation was somewhat suppressed but it was highly suppressed in the gradual order of none fertilizer level < standard fertilizer level < doubled fertilizer level in Ca treatment according to investigation after the first three hours passed away. But after the period, the ratio of appressorium formation promoted highly regardless of the level of fertilizer.

Induction of morphological deformities in Chironomus riparius larvae was assessed after exposure to 0.3, 1, 10 and 30 ${\mu}g\;L^{-1}$ potential endocrine disruption chemicals, Diethylhexyl phtalate (DEHP). We observed and subdivide types of mentum deformities and counted the incidence of mentum deformities. The mortality was not increased according to concentrations of DEHP, while was depend on the exposed days. The incidence of mentum deformities for MLT (median lateral teeth), LT (lateral teeth), and MIX (MLT+LT) of the mentum morphological structure showed MLT (2.8$\sim$11.4%)>LT (2.8$\sim$2.9%)>MIX (2.8$\sim$3.0%). The type of mentum deformities on C. riparius was classified six groups following exposure to DEHP. The incidence rate was occupied following to tooth addition (4.3%), tooth split (2.8%), tooth deletion (2.4%), tooth fusion (1.4%), $K"{o}hn$ gap (0.5%) and abnormal shape (0.5%). Especially tooth split and tooth fusion were observed in DEHP treated conditions.

The mediastinum is the most prevalent site of extragonadal teratomas. Patients with mediastinal mature teratomas are usually young adults, and the condition does not show significant sexual differences. Mediastinal teratomas are mostly located in the anterior mediastinum. Patients are usually asymptomatic, although they can have several complications when the teratomas become large or rupture. Most mediastinal teratomas can be diagnosed using CT. Diagnosing ruptured or malignant teratomas is challenging because of their atypical clinical and radiological presentations. In this article, we describe various manifestations of mediastinal teratomas, with an emphasis on radiologic features.

아기가 세상에 태어났을 때 아기와 산모의 건강에 대한 염려 다음에는 흔히 손가락과 발가락이 모두 10개씩 맞는지 물어보고 헤아려 본다. 우리 몸에서 비슷한 기능을 하는 구조물이 10개씩 되는 것은 손과 발 이외에는 그렇게 흔치 않다. 그래서인지 손에는 눈에 잘 띄지 않는 경한 기형에서부터 팔이 짧든지 손가락이 없는 심각한 변형까지 다양하게 나타난다. 손의 기형에 대해 알아보자.

Chiari type 1 malformation is a developmental condition characterized by cerebellar herniation and syringohydromyelia in human beings. It has been reported as a common condition in the cavalier King Charles spaniel that is similar to human Chiari type 1 malformations. However, there are few documentations of diagnosed Chiari type 1 like malformation in other breed dogs. Abnormalities compatible with such a malformation were identified by magnetic resonance imaging in 24 dogs with neurologic signs in this study. The dogs were 15 females and 9 males. Their breed were variable, and 6 of the dogs were maltese, 5 were shih-tzu. The dogs had a variety of neurological signs and the severity of cerebellar herniation, syringohydromyelia, intracranial intra-arachnoid cyst or hydrocephalus.

We report a case of the successful anatomical correction of the Taussig-Bing anomaly associated with the interrupted aortic arch and intramural left coronary artery for an 38 day-old infant Aortic arch and neoaortic reconstructions were conducted without any prosthetic or pericardial patch. Intramural left coronary was separated from right one after partial detachment of aortic commissure and both coronary artery buttons were transferred separately to the proximal main pulmonary artery(nee-aorta). Delayed sternal closure was done 3 days after the operation and hospital discharge was delayed for a month because of postoperative pneumonia. Now he is 5 months old and free of symptoms and cardiac drugs.
