Chronic kidney disease (CKD)-mineral and bone disorder (CKD-MBD) is a common complication of CKD, often accompanied by extra-skeletal calcification in adult patients. As increased vascular calcification is predicted to increase cardiovascular mortality and morbidity, the revised Kidney Disease: Improving Global Outcomes guidelines recommend avoiding calcium-containing phosphate chelators. However, extra-skeletal calcification is less commonly noticed in pediatric patients. Here, we report our experience of such a complication in pediatric patients receiving maintenance peritoneal dialysis. Extra-skeletal calcification was noticed at the corneas, pelvic cavity, and soft tissues of the lower leg in 4 out of 32 patients on maintenance peritoneal dialysis. These patients experienced the aggravation of extra-skeletal calcifications during peritoneal dialysis, and 2 of them underwent excisional operations. It is required to monitor extra-skeletal calcifications in children on kidney replacement therapy.

Intraoperative acetabular fractures (IAFs), a complication seldomly encountered in total hip arthroplasty, are typically a result of the impact of insertion of a cementless press-fit cup. Factors that contribute to the risk of these types of fractures include poor bone quality, highly sclerotic bone, and the use of a press-fit cup that is excessively large. The approach to management of these fractures is dependent on when they are identified. Immediate stabilization measures should be implemented for management of fractures detected during surgery. When fractures are detected postoperatively, the decision regarding conservative treatment is dependent on the stability of the implant and the specific fracture pattern. In the majority of cases, effective treatment of an acetabular fracture detected intraoperatively can be administered using a multi-hole revision cup along with anchoring screws in the various regions of the acetabulum. Selection of plate osteosynthesis of the posterior column is recommended when there is a large posterior wall fragment or pelvic discontinuity. In cases where anatomical dimensions allow, cup-cage reconstruction may offer a promising alternative to a combined hip procedure. The number of reports addressing the management of IAFs is limited. This review focuses on outlining the strategies that are currently available for management of this seldomly encountered complication.

Current study was conducted to investigate the effect of different hanging techniques (achilles tendon, aitch bone and pelvic ligament) on variations in sarcomere length and palatability within and between muscles using thirty-four Angus steer sides. Results showed that tenderstretch(by either suspension method) resulted in longer sarcomeres for most positions within the major leg muscle than did conventional hanging method, but in some minor muscles(eg., mm. gluteus profundus, gastronemius, and gracilis) tenderstetch allowed the muscles fibres to shorten. Some tenderstretched muscles(e.g., m. gluteus profundus, 1.5 ${\mu}m$) appeared not to toughen even at very low sarcomere lengths, while others toughened at higher sarcomere lengths. The current data demonstrated that the effect of tenderstretch on the length of sarcomeres and its influence on palatability varied between muscles, Overall the difference between the two tenderstretch methods was for the aitch method to produce meat that was 3.2 units more palatable than the ligament hanging method.

Pancreatic trauma occurs in 0.2% of patients with blunt trauma and 5% of severe abdominal injuries, which are associated with high mortality rates (up to 60%). Traumatic pancreatoduodenectomy (PD) has significant morbidity and appreciable mortality owing to complicating factors, associated injuries, and shock. The initial reconstruction in patients with severe pancreatic injuries aggravates their status by causing hypothermia, coagulopathy, and acidosis, which increase the risk for early mortality. A staging operation in which PD follows damage control surgery is a good option for hemodynamically unstable patients. We report the case of a patient who was treated by staging PD for an injured pancreatic head.

목 적: 전립선암의 소분할 방사선치료에서 골반뼈를 기준으로 한 준비자세(setup)와 전립선에 삽입된 위치표지자(fiducial marker)를 이용한 준자세를 비교하였다. 대상 및 방법: 2009년 9월부터 2010년 8월까지 전립선암으로 근치적 소분할 방사선치료를 받은 4명의 환자를 대상으로 하였다. 방사선치료 1주일 전경에 경직장초음파 검사 하여 3개의 위치표지자를 직장을 통하여 전립선에 삽입하였다. 방사선치료계획용 컴퓨터단층촬영과 매 방사선치료 전에 직장 관장을 하였다. 소분할 방사선치료는 노발리스 장치를 이용하여, 매일 3.5 Gy씩 총 59.5 Gy를 계획하였다. 분할조사 전에 서로 수직인 두 방향의 kV X-선을 촬영하여 얻은 영상의 위치표지자와 방사선치료계획의 디지털재구성사진에서 관찰되는 위치표지자를 융합하여, 환자의 자세를 조정하고 준비자세를 하였다. 위치표지자 기준 준비자세에서 방사선치료계획의 디지털재구성사진과 kV X-선 영상의 골반뼈를 가상적으로 융합하여, 골반뼈 기준 준비자세를 구하였다. 결 과: 67회의 분할조사를 분석하였다. 위치표지자 기준 준비자세에서 방사선치료 중심점과의 3차원적 위치 차이의 평균은 $0.94{\pm}0.62$ mm (범위, 0.09~3.01 mm; 중앙값 0.81 mm)였고 좌우, 상하, 전후 방향으로 위치 차이의 평균은 각각 $0.39{\pm}0.34$ mm, $0.46{\pm}0.34$ mm, $0.57{\pm}0.59$ mm였다. 골반뼈 기준 준비자세에서 방사선치료 중심점과의 3차원적 위치 차이의 평균은 $3.15{\pm}2.03$ mm (범위, 0.25~8.23; 중앙값, 2.95 mm)였고, 상하 방향의 위치 차이(평균, $2.29{\pm}1.95$ mm)가 전후(평균, $1.73{\pm}1.31$ mm), 좌우(평균 $0.45{\pm}0.37$ mm) 방향보다 유의하게 컸다(p<0.05). 위치표지자 기준 준비자세와 골반뼈 기준 준비자세들에서 방사선치료 중심점과의 3차원적 위치 차이가 3 mm 이상이었던 경우는 전체 분할방사선조사 횟수의 1.5%와 49.3%였고, 5 mm 이상이었던 경우가 각각 0%, 17.9%였다. 결 론: 위치표지자를 이용하여 보다 정확하게 준비자세를 함으로써 계획용표적체적의 여유를 줄일 수 있고, 따라서 전립선 주변의 정상조직에 대한 방사선량을 감소시켜 보다 안전하게 소분할 방사선치료를 할 수 있을 것으로 예상된다.

Objective : To investigate risk factors for S1 screw loosening after lumbosacral fusion, including spinopelvic parameters and paraspinal muscles. Methods : We studied with 156 patients with degenerative lumbar disease who underwent lumbosacral interbody fusion and pedicle screw fixation including the level of L5-S1 between 2005 and 2012. The patients were divided into loosening and non-loosening groups. Screw loosening was defined as a halo sign larger than 1 mm around a screw. We checked cross sectional area of paraspinal muscles, mean signal intensity of the muscles on T2 weight MRI as a degree of fatty degeneration, spinopelvic parameters, bone mineral density, number of fusion level, and the characteristic of S1 screw. Results : Twenty seven patients showed S1 screw loosening, which is 24.4% of total. The mean duration for S1 screw loosening was $7.3{\pm}4.1$ months after surgery. Statistically significant risk factors were increased age, poor BMD, 3 or more fusion levels (p<0.05). Among spinopelvic parameters, a high pelvic incidence (p<0.01), a greater difference between pelvic incidence and lumbar lordotic angle preoperatively (p<0.01) and postoperatively (p<0.05). Smaller cross-sectional area and high T2 signal intensity in both multifidus and erector spinae muscles were also significant muscular risk factors (p<0.05). Small converging angle (p<0.001) and short intraosseous length (p<0.05) of S1 screw were significant screw related risk factors (p<0.05). Conclusion : In addition to well known risk factors, spinopelvic parameters and the degeneration of paraspinal muscles also showed significant effects on the S1 screw loosening.

Objectives : The purpose of this study was to introduce the Chuna Manual Therapy (CMT) using Bong (a type of stick which is called 'bong') as a part of Oriental Medicine. Methods : We searched several traditional methods of CMT using Bong, either individual contact to specialist of CMT using Bong or referred to publications, and summarized briefly for introduction. Authors also made a comparative study between existing CMT and CMT using the bong. Results & Conclusions : The indications of Bong CMT are regarded as acute or chronic pain syndrome, whiplash associated disorders, facet syndrome, vertebral misalignment, chronic fatigue syndrome, obesity and also lower extremity length difference caused by malalignment of vertebrae and pelvic bone. The Meridian Muscle Therapy by pressing down using the Bong can be carried out on the imbalances of the muscle by shortening and lengthening contraction. CMT with Bong is considered more effective than other existing CMT in terms of effectiveness. In the case of pelvic correction which needs a tremendous amount of force, it can reduce the force required effectively. This fact can be inferred by the theory of composition and decomposition of force during the transmission of power. We can perform Bong CMT feeling less fatigued subsequently than general CMT. Pressing down with flexed fingers to grip bong acts on the contraction of flexor digiti and extensor digiti muscle, this protects the $doctor^{\circ}{\emptyset}s$ wrist joints from injury. The bong which acts as a tool between the doctor and the patient, while being given treatment, absorbs and spreads out the direct impact from the patient to the doctor. CMT with Bong is able to apply to both existing massage therapies with the hand. The bong appliance can be used in all applications, particularly, but not limited to; Orthopedic and Manual Correction Therapy, Meridian Muscle Pressing, Exercise Therapy, and Meridian Point Manual Pressing Therapy. CMT with Bong belongs to the category of oriental rehabilitation and Chuna manual medicine.

Blunt abdominal trauma may often cause multiple vascular injuries. However, common iliac artery injuries without associated bony injury are very rarely seen in trauma patients. In the present case, a 77-year-old male patient who had no medical history was admitted via the emergency room with blunt abdominal trauma caused by a forklift. At admission, the patient was in shock and had abdominal distension. On abdomino-pelvic computed tomography (CT), the patient was seen to have hemoperitoneum, right common iliac artery thrombosis and left common iliac artery rupture. During surgery, an additional injury to inferior vena cava was confirmed, and a primary repair of the inferior vena cava was successfully performed. However, the bleeding from the left common iliac artery could not be controlled, even with multiple sutures, so the left common iliac artery was ligated. Through an inguinal skin incision, the right common iliac artery thrombosis was removed with a Forgaty catheter and a femoral-to-femoral bypass graft was successfully performed. After the post-operative 13th day, on a follow-up CT angiography, the femoral-to-femoral bypass graft was seen to have good patency, but a right common iliac artery dissection was diagnosed. Thus, a right common iliac artery stent was inserted. Finally, the patient was discharged without complications.
