Revascularization of the pulp in a necrotic, infected immature tooth with apical periodontitis was attempting several years. Revascularization of partially necrotic pulp in an immature tooth is based on the concept that vital dental stem cells can survive pulpal necrosis. Revascularization procedure obtains longer and thicker roots in teeth with necrotic pulp diagnosis. Pulp revascularization for immature permanent molars can be possibly applied on cases having difficulty to use conventional root canal treatment due to abnormally thin root canal wall or severe root curvature. Also, when an uncooperative patient does not agree with sedative treatment the revascularization can be useful. And a patient with disability who is barely cooperative can be another indication of this treatment. In this case report, pulp revascularization using triple-antibiotics, metronidazole, ciprofloxacine and minocycline, was applied on the immature first permanent molar infected by caries.

괴사성 근막염은 흔하지 않은 질환으로서 때로 전격적인 진행을 보이며 흉벽에 생기는 경우에는 매우 드물다. 신체의 어느 부위나 생길 수 있으나 주로 복벽이나 서혜부, 사지 등에 가장 많이 발생한다. 이 질환의 특징은 근막의 괴사가 광범위하게 진행되지만 피부나 근육은 비교적 잘 보존되어 있다. 따라서 조기에 진단하기가 어려우므로 진찰당시 이 질환을 염두에 두어야 진단할 수 있다. 조기진단 후 즉각적인 외과적 치료가 가장 중요하다. 본 병원 흉부외과에서 흉벽에 발생한 특발성 괴사성 근막염을 한 례 경험하여 치료하였기에 문헌 고찰과 함께 보고하는 바이다.

Phlegmonous esophagitis is a disorder in which bacterial infection occurs in the submucosal and muscular layers of the esophagus. This malady is very rare and it is usually associated with high mortality. A 69-year-old male was admitted with chest pain and fever he'd experienced for 7 days. The chest computerized tomography scan revealed mediastinal widening, circumferential esophageal thickening, an air shadow along the esophagus and right pleural effusion. Drainage and debridement of the mediastinum and primary repair of the perforated esophageal muscular layer through a right thoracotomy was done immediately. Further surgical treatment was not performed. He had a good oral intake without dysphagia or esophageal leakage at discharge.

Bacterial endocarditis of the native aortic valve is associated with significant morbidity and mortality despite aggressive medical and surgical treatment, especially when perivalvular tissue was invaded and destructed. The pulmonary autograft is full viable and immune compatible tissue. This paper describes successful Ross operation as total root replacement in 38 years old native valve endocarditis patient with aortic root abscess.

Non-typhoid salmonella infection frequently associated with bacteremia rarely been reported in immunocom-promized patients with malignant neoplasms, diabetes or extended use of corticosteroids. Especially, concomitant pleural empyema and pericarditis due to non-typhoid salmonella. infection is extremely rare. Here, we report a case of concomitant empyema and pericarditis in malignant thymoma with pleural. metastasis complicated by salmonella group D infection with brief review of literature.

Aortic and pulmonary valve endocarditis with patent ductus arteriosus (PDA) is uncommon in adult. A 60-year-old woman was diagnosed with aortic and pulmonary valve endocarditis and PDA. We describe our surgical experience for treating PDA with double valve endocarditis.

Henoch-$Sch{\ddot{o}}nlein$ purpura (HSP) is a systemic disorder characterized by leukocytoclastic vasculitis that can affect multiple organs predominantly the skin, joints, gastrointestinal tract and kidney. Although the specific pathogenesis of HSP is not known, there are several hypotheses. Although the importance of the complement activation in glomerular injury in HSP has been suggested, the complement levels and the blood pressure in those patients are usually normal and massive proteinuria is not common. And pathologic renal changes also have been reported to show a large variety of glomerular changes. However, to our knowledge, a membranoproliferative glomerulo-nephritis (MPGN) is a rare renal clinicopathologic manifestation of HSP. We report a 6-year-old boy with HSP who developed MPGN with hypertension, massive proteinuria, and hypo-complementemia revealed activation of the classical complement pathway, although we could not exclude the possibility of other hypocomplementemic glomerulonephritis including post-streptococcal acute glomerulonephritis.

This study was performed on 16 patients diagnosed with tsutsugamushi disease and cerebral infarction from January 2007 to December 2015. An acute cerebral infarction was diagnosed by brain MRI and MRA. Tsutsugamushi disease was diagnosed using a polymerase chain reaction. To distinguish the difference between the generalized cerebral infarction and infarction with tsutsugamushi disease, the blood pressure and body temperature were measured uponadmission. In general, the blood pressure increases during an acute cerebral infarction. Interestingly, in this study, 12 patients showed a systolic blood pressure less than 130 mmHg uponadmission. The location of the cerebral infarction and whether single or multiple cerebral infarction were examined. Thirteen patients had a cerebral infarction in anterior circulation and 3 patients developed in posterior circulation. To evaluate the coagulation disorders, prothrombin time (PT), activated partial thromboplastin time (aPTT), D-dimer, fibrinogen, fibrin degradation product (FDP). D-dimer, which is generally known to increase in an acute cerebral infarction, showed a significant increase in the 13 patients. Fibrin degradation products (FDP) showed a significant increase in 15 patients. The pathophysiological mechanism of tsutsugamushi disease is known as vasculitis, which may result in an endothelial cell injury and proliferation of the endothelial wall, which may lead to a cerebral infarction accompanied by coagulopathy. Without endothelial cell damage and proliferation, a vasospasm caused by vasculitis may cause vasoconstriction and cerebral infarction.

Henoch-Sch$\ddot{o}$nlein purpura (HSP) is the most common vasculitis in children and is characterized by cutaneous purpura, arthritis, abdominal pain, and nephritis. Bullous skin lesions are rare in children. We report a case involving a 9-year-old female with HSP who displayed rapidly evolving hemorrhagic bullae from the primary purpuric lesions during systemic corticosteroid therapy. The bullae disappeared within 7 days of systemic corticosteroid therapy. Some scar lesions of the skin developed on acute phase recovered completely after 6 months. Bullae should not be considered as a poor prognostic factor of HSP and its renal outcome. Skin biopsy in HSP children with bullae is not necessary if clinical diagnostic criteria of HSP are met. However, further evaluation of more pediatric HSP with bullae is needed to get the clearer conclusions. We report a 9-year-old female with HSP who showed the rapidly evolving hemorrhagic bullae from primary purpuric lesions during systemic corticosteroid therapy.

다양한 연구에 따르면, 고려인삼은 허약한 체질, 숙취, 폐경과 월경불순, 초기 당뇨병, 영양실조, 빈혈 및 단백질 부족, 간기능 악화, 각종 독성물질에 기인한 중독, 피로, 추위, 스트레스, 산후조리, 체력쇠퇴 등에 효능이 있음이 알려져 있다. 특히 고려인삼은 혈관 기능을 효과적으로 조절함으로 고혈압, 뇌졸중, 심근경색, 동맥경화, 관절염, 당뇨, 비만 등의 질환을 효과적으로 치료하거나 예방할 수 있는 효능이 있음이 최근 연구에 의하여 밝혀지고 있다. 그러나 고려인삼 약리효능의 표적분자(target molecule)나 생화학적 작용기전(biochemical mechanism)이 세포 및 분자 수준에서 규명되지 못하여 고려인삼이 의약품으로 인정받지 못하고 건강식품으로 분류되고 있어 소비가 한인 흑인 히스패닉 시장에 한정되고 있고, 최근에는 타 경쟁국 인삼에 비해 수출 경쟁력이 약화되고 있는 실정이다. 본 연구에서는 고려인삼 추출물과 효능성분이 혈관내피세포 기능조절에 미치는 효능 및 작용기전을 규명하여 고려인삼이 호발성 혈관질환에 대한 예방 및 치료 효능이 있음을 분자 및 유전자 수준에서 확인하고자 하였다.
