흉선종의 흉곽밖으로의 전이는 드물다. 저자들은 흉선종이 거대 고립종괴 형태로 간 에 전이한 예를 경험하였으며 생검 결과 림프구성 흉선종으로 확진되었다. 초음파 및 CT 소견상종괴의 대부분은 낭성 종괴로 나타났으며 변연부에는 불규칙하고 두꺼운 고형종괴 부 위가 있었고 비교적 얇고 매끈한 피막으로 둘러싸여 있다. Extrathoracic metastasis of a thymoma is rare; we report a case of metastasis to the liver of a large solitary thymoma. Biopsy of the mass showed it to be predominantly lymphocytic and histologically the same as a primary thymoma operated on four years previously. On ultrasound and CT scan, the majority of the metastatic tumor was hemorrhagic, necrotic and/or cystic, with a peripheral, irregularly thick solid component and rather thin, smooth encapsulation.

Our clinical experiences have indicated that there would be a close relationship between chronic upper respiratory tract infection such as chronic paranasal sinusitis and lower lung inflammatory disease. The present study has been undertaken to retrospectively correlate the incidence of chronic paranasal sinusitis and pulmonary inflammatory disease in the clinical patients. The material consisted of 507 patients seen at the Dept. of Radiology, St. Mary's Hospital, Catholic Medical College during the period of Jan. 1973 through Sept. 1977. All patients had at least one chest radiogram and one or more paranasal sinus-series examinations. In our series there were 371 cases of sinusitis. Of these, 62 cases (17%) had X-ray findings suggesting chronic lung inflammations. The break down of 62 cases showed 42 cases (11.3%) of chronic aspirational pneumonia and 20 patients (5.4%) bronchiectasis and/or chronic bronchitis. Chronic aspirational pneumonia prevailed in the childhood and eld rly groups whereas chronic bronchitis and bronchiectasis in the middle and elderly subjects. The degree of sinusitis did not parallel the intensity of chronic lung inflammatory change.
중소기업 근로자의 내부 및 외부고용가능성과 이직의도 간 관계에서 경력몰입의 매개효과

본 연구는 중소기업 근로자를 대상으로 내부 및 외부고용가능성과 이직의도 간 관계를 규명하고, 이 관계에서 경력몰입이 갖는 매개효과에 대해 검증하는 것을 목적으로 한다. 이를 위해 근로자 수 300인 미만의 중소기업 근로자를 대상으로 패널 조사를 실시하였다. 이 연구의 결과는 다음과 같다. 첫째, 중소기업 근로자의 내부고용가능성은 이직의도에 부(-)적 영향을 미치는 것으로 나타났으며, 중소기업 근로자의 외부고용가능성은 이직의도에 유의미한 영향을 미치지 않는 것으로 확인되었다. 둘째, 중소기업 근로자의 내부고용가능성과 이직의도 간 관계에서 경력몰입은 매개효과를 갖는 것으로 나타났으며, 중소기업 근로자의 외부고용가능성과 이직의도 간 관계에서도 경력몰입은 매개효과를 갖는 것으로 확인되었다.
Gummy Smile과 과개교합을 동반한 II급 부정교합 환자의 미니스크루를 이용한 비발치 교정치료
강시원 대한치과교정학회 2021 대한치과교정학회 임상저널 Vol.11 No.1
Gummy smile is a clinical condition that refers to excessive gingival display during smile, which is often accompanied by vertical dentoalveolar excess in the anterior region. With orthodontic miniscrews, three-dimensional total arch movement, including intrusion without side effects on the anchor tooth can be achieved. But proper biomechanical understanding and careful monitoring are required to design an appropriate force system and to prevent unwanted side effects. An 18-year-old girl presented with chief complaints of gummy smile and crowding. She showed a deep bite and skeletal Class II relationship. The patient was treated with total arch intrusion and distalization using two maxillary inter-premolar orthodontic miniscrews which provided biomechanically effective force system to correct the gummy smile. Counter-clockwise autorotation of the mandible was also obtained improving her facial profile.

Tracheoesophageal fistula (TEF) in adult patients is an uncommon complication in leukemia. We present here on a case of TEF in a 46-year-old woman with ALL. The patient was asymptomatic and TEF is resulted from aspergillus bronchitis during the chemotherapy for acute lymphoblastic leukemia (ALL). 백혈병 환자에서 기관지 식도 누출공은 매우 드믄 합병증이다. 저자들은 최근 46세 여자, 림프모구성 백혈병환자에서 화학요법 중에, 침습성 아스페르길루스증 합병으로 발생된 기관지 식도 누출공 1예를 경험하였기에 문헌고찰과 함께 보고한다.
상악의 수직적 과잉과 Gummy Smile을 동반한 장안모 돌출 환자에서 효율적인 수직조절 치료전략

In the treatment of a hyperdivergent patient, making sufficient facial change without surgery is challenging because the chin is retrusive, rotated backwardly. The patient may be still protrusive after the treatment if sagittal retraction is only performed. Since the mandible moves in a rotational manner, vertical control can result in significant sagittal correction in profile through the autorotation of the mandible. Since the orthodontic mini-implant is a very effective tool for vertical control, especially, for intrusion, it can play a crucial role in making facial change for a hyperdivergent patient. A 24-year-old girl was presented with chief complaints of protrusion and gummy smile. Her profile showed protrusion, lip incompetency and very retrusive chin. She showed excessive gingival display during smiling. Her diagnosis included skeletally hyperdivergent Class II pattern, anteriorly and vertically excessive maxilla. The patient was treated with total arch intrusion in maxilla and mandible using two orthodontic mini-implants for each arch. Total arch intrusion in both arches created counter-clockwise autorotation of the mandible which dramatically improved her profile. Intrusion in the maxillary anterior region decreased excessive gingival display and made an attractive smile for the patient.
