Penetrating neck injuries constitute 5-10% of all trauma cases. These injuries may cause life-threatening suppurative or vascular complications, but the severity and extent of damage depends upon the inflicting object and the involved structures. If significant complications are not expected, then it is best to leave the foreign body embedded and avoid surgical risks. We present a rare case of a foreign body embedded in the neck causing tinnitus and foreign body sensation.

Drug abuse has become a major social problem of the modern world and majority of these abusive drugs or their metabolites are excreted through the kidneys and, thus, the renal complications of these drugs are very common. Morphine, heroin, cocaine, nicotine and alcohol are the most commonly abused drugs, and their use is associated with various types of renal toxicity. The renal complications include a wide range of glomerular, interstitial and vascular diseases leading to acute or chronic renal failure. The present review discusses the renal toxicity profile and possible mechanisms of commonly abused drugs including morphine, heroin, cocaine, nicotine, caffeine and alcohol.

The purposes of this article are to review the pathogenesis, prevention, and management of amputation due to diabetes mel1itus complications, and to report one case who had lost his toes due to diabetes mellitus. A primary cause for hospital admission of the patient was foot ulcer. Since many amputations in diabetic patients are precipitated by such ulcers, a program for active prevention and optimal treatment of diabetic foot lesions might decrease the risk of amputation. Diabetic foot ulcers and, ultimately, amputation can stem from a variety of pathways. The combination of peripheral neuropathy, peripheral vascular disease and infections is the harbinger of the final cataclysmic events of gangrene and amputation. As the physical therapist is often involved in the treatment of diabetic patients, the therapist should be aware of the followings: the patient's type of diabetes and the severity of the diabetes, the complications of the disease, the effects of exercise, the importance of wearing proper shoes and education to patients about appropriate diabetic foot care.

We experienced one case of surgical treatment of A-V fistula between the right common iliac artery and the right common iliac vein after lumbar laminectomy. The average vascular surgeon does not have extensive experience with this disorder owing to its rarity. Arteriovenous fistula of the aorta and its major branches present an unparalleled challenge in patient care. Because of their central location, blood flow through these fistulas may be massive;the associated complications are usually dramatic, resulting in severe refractory congestive heart failure, massive venous hypertension, or extensive hemorrhage during an illfated surgical repair.For this reason, it behooves one to become well acquainted with the problem in order to avoid morbid complications and thus ensure optimal patient care.

Arthroscopic shoulder procedures are one of the most common procedures used to restore function through minimally invasive techniques. With the demand for shoulder arthroscopic procedures comes the need for safe, effective, and efficient surgery that maximizes patient outcomes while minimizing complications. Many variables contribute to visualization in shoulder arthroscopy including vascular anatomy, blood pressure control, arthroscopic pump systems, turbulence control, epinephrine, and tranexamic acid. Furthermore, patient positioning can have a dramatic effect on visualization with both the beach chair position and lateral decubitus positioning having various strengths and weaknesses depending on the intended procedure being performed. The purpose of this review is to examine the benefits and complications reported in the literature for improving visualization in shoulder arthroscopy.

9개월령의 암컷 말티즈견과 1년령의 암컷 비글견이 지속성 심잡음을 주증으로 내원 하였다. 두 환축은 2차원 심초음파 및 심혈관조영술을 통해 동맥관개존증 (PDA)으로 진단되었다. 평가된 환축들의 동맥관 사이즈는 비교적 큰 편이었으며, 혈관 폐색장치 중 Amplatzer$^{(R)}$ vascular plug를 통한 동맥관의 폐쇄술이 시도 되었다. 말티즈 견의 경우, Amplatzer$^{(R)}$ vascular plug를 이용하여 동맥관의 완전폐쇄가 이루어 졌으며, 폐쇄직후 지속성 심잡음이 사라졌다. 비글견의 경우, Amplatzer$^{(R)}$ vascular plug 삽입 후 심잡음이 줄어들긴 했지만, 심혈관 조영검사에서 잔류혈류가 관찰되었다. 시술의 안전성 및 시술 후 합병증은 두 환자 모두에서 지속적으로 모니터링 되었다. 본 2 증례는, Amplatzer$^{(R)}$ vascular plug를 이용한 성공적인 동맥관개존증 폐쇄술에 대한 국내 첫 증례보고이다.

Background Myelomeningocele is a frequently seen condition at tertiary care hospitals. Its treatment involves a variety of plastic reconstructive techniques. Herein, we present a series of myelomeningocele patients treated using keystone flaps. Methods We gathered information regarding soft tissue reconstruction and the use of bilateral keystone flaps to treat myelomeningocele patients. We obtained data from clinical records and recorded the demographic characteristics of mothers and children with the condition. The size, level of defect, and complications detected during the follow-up were analyzed. Results A series of seven patients who underwent bilateral keystone flaps for myelomeningocele closure was analyzed. There were no cases of midline or major dehiscence, flap loss, necrosis, surgical site infections, or cerebrospinal fluid leakage. No revision procedures were performed. Minor complications included one case with minimal seroma and three cases with areas of peripheral dehiscence that healed easily using conventional measures. Conclusions The use of keystone flaps is an adequate option for closure of dorsal midline soft tissue defects related to myelomeningocele. This technique offers predictable results with an acceptable spectrum of complications. Robust blood flow can be predicted based upon anatomical knowledge.

Although Behcet`s disease, characterized by oro-genital ulceration and ocular abnormalities, is rare and unfamiliar disease to thoracic surgeon, one must remember that it can cause serious complications on the vascular system such as thrombophlebitis,thrombotic obstuction and aneurysm.We report a case of multiple arterial aneurysms with Behcet`s disease. This 31 year-old female had five times surgical interventions during short period[19 months]. 6 aneurysms were developed in this case, 3 were spontaneous aneurysms, 2 were anastomotic aneurysms and 1 was false aneurysm due to arterial puncture.

허혈/재관류 손상은 장기이식 분야에서 해결해야 할 주요 문제점으로 알려져 있다. 본 연구에서는 대퇴 동,정맥 부위에서 기존의 혈관 문합법 대신 맥관 connector를 이용하여 간단하면서 효과적인 체외 재관류 모델을 개발하였기에 소개하고자 한다. 개발된 모델이 허혈/재관류 손상연구에 효과적인지 알아보기 위해 혈액 동력학적 평가와 신장의 재관류 후 손상 양상을 분석하였다. 기존의 재관류 모델에서 사용되는 문합 부위인 복강 대동맥의 혈압과 본 연구에서 재관류 부위로 활용된 대퇴동맥의 혈압은 유의적 차이가 없었다. 허혈 손상 후 재관류 효과를 알아보기 위해 미니돼지에서 적출한 신장을 HTK 용액에 24, 48시간 동안 각각 저온보관 후 대퇴부에 이식하여 재관류 한 결과, 신장의 재관류까지 수술시간은 평균 $7.0{\pm}1.1$분 소요되었으며, 3시간 재관류 후 재관류 손상 정도는 저온보관시간에 따라 증가되는 것이 확인되었다. 이는 개발된 모델이 맥관 문합 없이 간단한 관류방법이면서도 기존의 복잡한 수술에 의한 재관류 방법과 유사한 손상 모델을 만들 수 있는 효과적인 허혈/재관류 동물모델이라는 것을 의미한다. 따라서 본 연구에서 개발한 신장 재관류 모델은 초기 허혈/재관류 손상 연구와 장기이식에서 이식면역연구에 효과적인 모델이라 사료된다.

Purpose: To investigate the efficacy, safety, and anatomical outcomes associated with intravitreal anti-vascular endothelial growth factor (VEGF) treatment of retinopathy of prematurity (ROP). Methods: We performed a retrospective review of intravitreal anti-VEGF (bevacizumab or ranibizumab) treatment of 153 eyes (83 infants) diagnosed with ROP at two tertiary hospitals from June 2011 to January 2017. The primary outcome was the rate of recurrence requiring additional treatment; secondary outcomes included incidence of major complications and final refractive error. Results: A total of 101 eyes were treated with bevacizumab, and 52 with ranibizumab. The bevacizumab and ranibizumab groups were characterized by mean birthweights of $941.8{\pm}296.1$ and $1,257.7{\pm}514.5g$, gestational ages at birth of $26.9{\pm}1.9$ and $28.1{\pm}3.2$ weeks, and postmenstrual ages at treatment of $40.4{\pm}2.4$ and $39.2{\pm}2.3$ weeks, respectively. The two groups differed significantly in birthweights and gestational ages at birth, but not in postmenstrual ages at treatment. The mean follow-up duration was $30.9{\pm}18.4$ months for the bevacizumab group, and $13.9{\pm}12.5$ months for ranibizumab. More cases were classified as zone 1 ROP in the ranibizumab group (44.2% vs. 11.9%, p < 0.001). Major surgical interventions included scleral encircling and vitrectomy (one and two eyes, respectively, both in the bevacizumab group). Retinal detachment was noted in one eye treated with bevacizumab. There was no significant difference in the most recent spherical equivalence for the two groups ($+0.10{\pm}3.66$ and $+0.22{\pm}3.00$ diopters for bevacizumab and ranibizumab, respectively). Univariable analysis revealed that only ROP stage influenced the occurrence of major complications (odds ratio, 9.046; p = 0.012). Conclusions: Intravitreal anti-VEGF treatment of ROP with both bevacizumab and ranibizumab achieved stable retinal vascularization with a low rate of complications and recurrence. Ranibizumab achieved similar anatomical outcomes as bevacizumab, without additional risk for major complications.
