두 형태 진균은 자연환경이나 배지에 접종하여 실온에($25{\sim}30^{\circ}C$)에서 배양하면 균사체를 형성하는 특성을 가지고 있으며, 체온이나 높은 온도($35{\sim}37^{\circ}C$)에서 배양을 하면 효모형태를 나타나는 특성이 있다. 풍토병 지역에서만 발생하는 이들은 전신감염을 일으키며, 조직이나 기관에 침입하여 심부 진균 증을 일으키는 원인 진균이다. 사람에 감염되는 두 형태 진균은 지금까지 Blastomyces dermatitidis, Coccidioides immitis, Sporothrix schenkii, Talaromyces (Penicillium) marneffei, Histoplasma capsulatum, 그리고, Paracoccidioides brasiliensis 여섯 균종으로 알려져 있다. 지금까지 해외에서 유입되어 국내에 보고된 두 형태 진균은 Coccidioides immitis가 18예, Histoplasma capsulatum이 5예, Blastomyces dermatitidis가 3예, 그리고 Talaromyces (Penicillium) marneffei 가 4예로 모두 30예의 두 형태 진균이 보고되었다. 유행지역의 방문경험이 없음에도 국내에 발생된 경우는 C. immitis가 3예, H. capsulatum이 2예, B. dermatitidis가 1예, 그리고 Talaromyces (Penicillium) marneffei 가 1예로 있다. Sporothrix schenkii 를 제외한 모든 두 형태 진균이 국내에서는 발생하지 않고 외국의 특정 국가와 한정된 지역에서만 발생하는 풍토병 원인의 토착 진균이지만, 유행 지역의 여행 경험이나 호발 지역의 이민 거주자들의 귀국과 국내로 유입되는 외국인의 증가 추세를 고려하면 해외유입 감염증의 발생은 점점 증가할 것으로 사료된다.

Objective : The objective of this study is to investigate the safety, surgical efficacy, and advantages of a polyaxial screw-rod system for posterior occipitocervicothoracic arthrodesis. Methods : Charts and radiographs of 32 patients who underwent posterior cervical fixation between October 2004 and February 2006 were retrospectively reviewed. Posterior cervical polyaxial screw-rod fixation was applied on the cervical spine and/or upper thoracic spine. The surgical indication was fracture or dislocation in 18, C1-2 ligamentous injury with trauma in 5, atlantoaxial instability by rheumatoid arthritis (RA) or diffuse idiopathic skeletal hyperostosis (DISH) in 4, cervical spondylosis with myelopathy in 4, and spinal metastatic tumor in 1. The patients were followed up and evaluated based on their clinical status and radiographs at 1, 3, 6 months and 1 year after surgery. Results : A total of 189 screws were implanted in 32 patients. Fixation was carried out over an average of 3.3 spinal segment (range, 2 to 7). The mean follow-up interval was 20.2 months. This system allowed for screw placement in the occiput, C1 lateral mass, C2 pars, C3-7 lateral masses, as well as the lower cervical and upper thoracic pedicles. Satisfactory bony fusion and reduction were achieved and confirmed in postoperative flexion-extension lateral radiographs and computed tomography (CT) scans in all cases. Revision surgery was required in two cases due to deep wound infection. One case needed a skin graft due to necrotic change. There was one case of kyphotic change due to adjacent segmental degeneration. There were no other complications, such as cord or vertebral artery injury, cerebrospinal fluid leak, screw malposition or back-out, or implant failure, and there were no cases of postoperative radiculopathy due to foraminal stenosis. Conclusion : Posterior cervical stabilization with a polyaxial screw-rod system is a safe and reliable technique that appears to offer several advantages over existing methods. Further biomechanical testings and clinical experiences are needed in order to determine the true benefits of this procedure.

By means of microsurgical free-tissue transfer providing a large amount of required tissue, the surgeon can resect tumoral tissue more safely, which allows tumor-free margins and enhances the reliability of the ablative surgery that otherwise could not be performed radically. The morbidity of elective free-tissue transfer seems to be quite low, carrying acceptable risks for most patients. But the elderly patients are at risk for cardiac and respiratory problems, deep vein thrombosis, pulmonary emboli and infection merely as a function of age. This study was undertaken to define further risks of the elderly population with regards to free-tissue transfer. We retrospectively reviewed our experience with 110 microsurgical free-tissue transfers for head and neck reconstruction in patients greater than 60 years of age. Microsurgical procedures in all cases were preformed by the plastic and reconstructive department at Yonsei medical center. The investigated parameters were patient demographics, past medical history, American Society of Anesthesiologists(ASA) status, site and cause of defect, the free tissue transferred and postoperative complication including free-flap success or failure. There were 46 patients in the age group from 60 to 64 years, 34 patients from 65 to 70 years, and 30 patients 70 years or older. There happened 3 flap losses, resulting in a flap viability rate of 97%. Patients with a higher ASA designation experienced more medical complication(p=0.05, 0.01, 0.03 in each age group I, II, III) but not surgical complication p=0.17, 0.11, 0.54 in each age group I, II, III). And the relationship between postoperative complication and age groups was not significant. These observations suggest that major determinant for postoperative medical complication be the patient's American Society of Anesthesiologists score, and chronologic age alone should not be an exclusion criterion when selecting patients for free-tissue transfer

목적: 급성 전방십자인대 손상 환자에서 조기 재건술과 지연 재건술 간의 관절 강직 발생 정도와 임상적 결과를 비교하고자 하였다. 대상 및 방법: 2008년 3월부터 2010년 10월까지 급성 전방십자인대 손상 환자 중 전방십자인대 재건술을 시행한 34예를 대상으로 하였다. 수상 후 1주 이내에 재건술을 시행한 조기 재건군과 수상 후 3주에서 6주 사이에 재건술을 시행한 지연 재건군으로 나누어 수술 전까지 적극적인 관절 운동을 시행하고 술 후에 환자 스스로 운동이 가능하도록 하는 적극적인 재활 치료를 시행한 후 관절 운동 범위, Lachman 검사, pivot shift 검사, Lysholm 점수, International Knee Documentation Committee (IKDC) 점수, Tegner 활동도 점수를 이용하여 평가하였다. 결과: 최종 추시에서 Lysholm 점수는 조기 재건군 91.82점, 지연 재건군 94.83점이었고 IKDC 점수는 전례에서 B (거의 정상) 이상으로 회복되었다(P=0.217, P=0.845). Tegner 활동도 점수는 조기 재건군 6.7점, 지연 재건군 7.1점이었고 (P=0.840) 관절 운동 범위는 양군 간에 차이가 없었으며(P=0.873, P=0.873) 심부 정맥 혈전증이나 감염은 전례에서 발생하지 않았다. Lachman 검사, pivot shift 검사 결과도 양군 간에 유의한 차이는 없었다(P=0.606, P=0.118). 결론: 급성 전방십자인대 손상 환자에서 조기 및 지연 재건군 모두에서 만족할만한 임상적 결과를 얻었다. 따라서 수상 후 1주 이내에 시행하는 조기 재건술도 좋은 치료 방법의 하나로 선택될 수 있을 것이라 생각된다.

For years, physicians and anatomists have been interested in the heart that has one functioning ventricle. Various terms have been suggested for this entity including single ventricle, common ventricle, double-inlet left ventricle, cor biatriatum triloculare, and primitive ventricle. In this report, the term "single ventricle" is utilized as suggested by Van Praagh, and is defined as that congenital cardiac anomaly in which a common or separate atrioventricular valves open into a ventricular chamber from which both great arterial trunks emerge. An outlet chamber, or infundibulum, may or may not be present and give rise to the origin of either of the great arteries. This definition excludes the entity of mitral and tricuspid atresia. An 11 year old cyanotic boy was admitted chief complaints of exertional dyspnea and frequent upper respiratory infection since 2 weeks after birth. He was diagnosed as inoperable cyanotic congenital heart disease, and remained without any corrective treatment up to his age of 11 year when he suffered from aggravation of symptoms and signs of congestive heart failure for 2 months before this admission. On 22nd of May 1979, he was admitted for total corrective operation under the impression of tricuspid atresia suggested by a pediatrician. Physical check revealed deep cyanosis with finger and toe clubbing, and grade V systolic ejection murmur with single second heart sound was audible at the left 3rd intercostal space. Development was moderate in height [135 cm] and weight[28Kg]. Routine lab findings were normal except increased hemoglobin [21.1gm%], hematocrit [64 %], and left axis deviation with left ventricular hypertrophy on EKG. Cardiac catheterization and angiography revealed 1-transposition of aorta, pulmonic valvular stenosis, double inlet of a single ventricle with d-loop, and normal atriovisceral relationship [Type III C solitus according to the classification of Van Praagh]. At operation, longitudinal incision at the outflow tract of right ventricle in between the right coronary artery and its branch [LAD from RCA] revealed high far anterior aortic valve which had fibrous continuity with mitral annulus, and pulmonic valve was stenotic up to 4 mm in diameter positioned posterolaterally to the aorta. Ventricular septum was totally defective, and one markedly hypertrophied moderator band originated from crista supraventricularis was connected down to the imaginary septum of the ventricular cavity as a pseudoseptum of the ventricle. Size of the defect was 3X3 cm2 in total. Patch closure of the defect with a Teflon felt of 3.5 x 4 cm2 was done with interrupted multiple sutures after cut off of the moderator band, which was resutured to the artificial septum after reconstruction of the ventricular septum. Pulmonic valvotomy was done from 4 mm to 11 mm in diameter thru another pulmonary arteriotomy incision, and right ventriculotomy wound was closed reconstructing the right ventricular outflow tract with pericardial autograft of 3 x 4 cm2. Atrial septal defect of 2 cm in diameter was closed with 3-0 Erdeck suture, and atrial wall was sutured also when rectal temperature reached from 24`C to 35.5`C. Complete A-V block was managed with temporary external pacemaker with a pacing rate of 110/min. thru myocardial wire, and arterial blood pressure of 80/50 mmHg was maintained with Isuprel or Dopamine dripping under the CVP of 25-cm saline. Consciousness was recovered one hour after the operation when his blood pressure reached 100 /70 mmHg, but vital signs were not stable, and bleeding from the pericardial drainage and complete anuria were persisted until his heart could not capture the pacemaker impulse, and patient died of low output syndrome 320 min after the operation.
