  • The dorsal metacarpal artery perforator flap is a flap that rises from the hand dorsum. Owing to its reliability and versatility, this flap is used as a workhorse for finger defect. However, to cover the radial-volar defect of the proximal interphalangeal joint (PIPJ) of the index finger, a longer flap is required than before. Here, we introduce the oblique extended reverse first dorsal metacarpal artery (FDMA) perforator flap to cover the radial-volar aspect defect of the index finger. A 45-year-old man got injured to the radial-volar defect of PIPJ of the left index finger caused by thermal press machine. The wound was 2 × 1 cm in size, and the joint and bone were exposed. We used FDMA perforator from anastomosis with palmar metacarpal artery at metacarpal neck. Since the defect was extended to the volar side, the flap was elevated by oblique extension to the fourth metacarpal base level. The fascia was included to the flap, and the flap was rotated counterclockwise. Finally, PIPJ was fully covered by the flap. Donor site was primarily closed. After 12 months of operation, the flap was stable without complication and limitation of range of motion. The oblique extended reverse FDMA perforator flap is a reliable method for covering the radial-volar defect of the PIPJ of the index finger. This flap, which also has an aesthetic advantage, will be a good choice for hand surgeons who want to cover the PIPJ defect of the index finger using a nonmicrosurgical option.

  • 선천성 심낭내 좌심방이류는 매우 드문 질환이다. 대부분의 경우 증상이 없으며 일반적으로 성인 환자에서 우연히 진단된다. 상심실성부정맥과 치명적인 혈전색전증의 발생이 문제되며, 무증상의 환자에서도 이를 예방하기 위해 진단 즉시 수술이 추천된다. 저자들은 45세 남자 환자에서 뇌졸증을 병발한 선천성 심낭내 좌심방이류의 수술적 제거를 치험하였기에 보고하는 바이다.

  • A carotid-cavernous sinus fistula is a rare condition in which an abnormal communication exists between the internal or external carotid artery and the cavernous sinus. It typically occurs within a few weeks after craniomaxillofacial trauma. In most cases, the carotid-cavernous sinus fistula occurs on the same side as the craniomaxillofacial fracture. We report a case of delayed carotid-cavernous sinus fistula that developed symptoms 7 months after the craniomaxillofacial fracture. The fistula developed on the side opposite to that of the craniomaxillofacial fracture. Based on our experience with this case, we recommend a long follow-up period of 7-8 months after the occurrence of a craniomaxillofacial fracture. We also recommend that the follow-up should include consideration of the side contralateral to the injury.

  • Listeriosis is a rare foodborne infection caused by Listeria monocytogenes. It is 12-20 times more prevalent in pregnant women compared to the general population, with a 20-40% mortality rate in neonates. Early treatment with appropriate antimicrobial agents is critical for pregnancy outcomes; however, the infection is difficult to control because the nonspecific clinical manifestations and rarity of the disease often preclude early diagnosis. We encountered 2 cases of pregnancy-associated listeriosis that occurred at 29 and 37 weeks of gestation. Both neonates were delivered by emergent cesarean section due to fetal condition, and one of the preterm infants died immediately after birth. Pregnancy-associated listeriosis should be considered in the management of unexplained fever or inflammatory conditions in pregnant women.

  • Objective : The effects on neural proliferation and differentiation of neural stem cells (NSC) of basic fibroblast growth factor-2 (bFGF). insulin growth factor-I (IGF-I). brain-derived neurotrophic factor (BDNF). and nerve growth factor (NGF) were assessed. Also, following combinations of various factors were investigated : bFGF+IGF-I, bFGF+BDNF, bFGF+NGF, IGF-I+BDNF, IGF-I+NGF, and BDNF+NGF. Methods : Isolated NSC of Fisher 344 rats were cultured with individual growth factors, combinations of factors, and no growth factor (control) for 14 days. A proportion of neurons was analyzed using $\beta$-tubulin III and NeuN as neural markers. Results : Neural differentiations in the presence of individual growth factors for $\beta$-tubulin III-positive cells were : BDNF, 35.3%; IGF-I, 30.9%; bFGF, 18.1%; and NGF, 15.1%, and for NeuN-positive cells was : BDNF, 34.3%; bFGF, 32.2%; IGF-I, 26.6%; and NGF, 24.9%. However, neural differentiations in the absence of growth factor was only 2.6% for $\beta$-tubulin III and 3.1% for NeuN. For $\beta$-tubulin III-positive cells, neural differentiations were evident for the growth factor combinations as follows : bFGF+IGF-I, 73.1 %; bFGF+NGF, 65.4%; bFGF+BDNF, 58.7%; BDNF+IGF-I, 52.2%; NGF+IGF-I, 40.6%; and BDNF+NGF, 40.0%. For NeuN-positive cells : bFGF+IGF-I, 81.9%; bFGF+NGF, 63.5%; bFGF+BDNF, 62.8%; NGF+IGF-I, 62.3%; BDNF+NGF, 56.3%; and BDNF+IGF-I, 46.0%. Significant differences in neural differentiation were evident for single growth factor and combination of growth factors respectively (p<0.05). Conclusion : Combinations of growth factors have an additive effect on neural differentiation. The most prominent neural differentiation results from growth factor combinations involving bFGF and IGF-I. These findings suggest that the combination of a mitogenic action of bFGF and post-mitotic differentiation action of IGF-I synergistically affects neural proliferation and NSC differentiation.

  • 본 연구는 찬공기 특성을 유역단위로 분석하고, 유역 내 생성되는 찬공기를 도시 바람길 계획에서 활용하는 방안을 제안하는 것을 목적으로 한다. 이를 위해, 경기도 지역의 북쪽에 위치한 중랑천 유역의 의정부시, 남쪽에 위치한 안양천 유역 및 양재천 탄천 유역의 과천시를 연구 대상지로 선정하였다. 찬공기 특성 분석을 위해 독일에서 개발된 모형인 KALM(Kaltluftabflussmodell)을 활용하였으며, 야간 6시간 동안 생성되는 찬공기 흐름 및 찬공기층 높이를 파악하였다. 중랑천 유역의 주요 바람길이 흐르는 곳에 위치해 있는 의정부시는 남쪽 외곽에서부터 유입된 찬공기가 의정부시 전체 바람길 계획의 중요한 부분을 차지하고 있다. 또한, 서쪽의 사패산 일대에서 생성된 찬공기는 시청 인근의 중심상업지구까지 유입되고 있어 도심의 열환경을 조절하는 주요한 역할을 수행하는 것으로 판단된다. 반면, 의정부시 동쪽지역은 바람길 이용이 원활하지 않는 것으로 파악되었다. 동쪽의 관악산과 서쪽의 청계산 등에서 생성된 찬공기 흐름은 과천시의 북쪽 지역에서 가장 활발하였는데, 이 흐름은 안양천 및 양재천 탄천 유역 전체에서도 주요한 바람길이다. 이에 비해, 찬공기 흐름이 원활하지 않은 남쪽지역에 '과천지식정보타운 공공주택지구' 조성이 계획되어 있어 향후 이 지역의 주거환경이 저하될 가능성이 크다. 향후, 이 지역을 개발할 경우 상세한 바람길 분석을 통한 바람길 활용 계획을 추가적으로 수립할 것을 제안하였다.

  • 2018년에 새롭게 개정된 장기 손상척도는 이전 미국외상수술협회의 응급수술분류체계와 유사한 형식을 가지며, 고형장기 손상의 등급을 지정하는 기준을 영상(imaging), 수술(operative), 병리(pathologic) 세 가지 세트로 나누어 분류하였다. 2018년 개정에서 가장 중요한 변화는 거짓동맥류와 동정맥 누공을 포함한 혈관 손상의 다중검출CT (multidetector CT; 이하 MDCT) 소견을 정의하여 장기 손상척도에 통합한 것이다. 이전 장기 손상척도와 동일하게 세 가지 기준 중에 가장 높은 등급이 최종 등급이 된다. 또한 한 장기 내에 여러 개의 1등급 또는 2등급 소견이 있으면, 다발성 손상에 대해 3등급의 부여가 가능하다. 본 임상화보에서는 2018년 개정된 미국외상수술협회 장기 손상척도의 MDCT 소견을 소개하고자 한다.
