Objective : Kyphoplasty and vertebroplasty are two minimally invasive procedures for osteoporotic vertebral compression fractures. The purpose of this retrospective study was to compare the radiological findings and clinical outcomes between two procedures. Methods : Osteoporotic vertebral fractures were treated in 76 vertebrae, using kyphoplasty (n=35 vertebrae) and using vertebroplasty (n=41 vertebrae). Fractured vertebral bodies were diagnosed by correlating the clinical symptoms with radiologic study. The responses of pain symptoms were measured by a self-reported Visual Analog Scale (VAS) score. Plain X-rays were checked preoperatively and postoperatively at admission and 6 months. The vertebral body height and kyphotic angle were measured to assess the reduction of the sagittal alignment. Results : The mean pain scores were decreased significantly for both procedures postoperatively, but there were no significant differences between two groups. Kyphoplasty led to a significant reduction of the vertebral body height and improvement of kyphotic angle. There were no neurological deficits after kyphoplasty, but one patient experienced paraparesis after vertebroplasty. During the 6 months follow-up both procedures provided stabilization of the sagittal alignment. Conclusion : Kyphoplasty and vertebroplasty are considered effective minimally invasive techniques for the stabilization of osteoporotic vertebral body fractures, leading to a statistically significant reduction in pain. Kyphoplasty significantly restore sagittal alignment. Also, complications and the incidence of bone cement leakage are significantly lesser than vertebroplasty. Therefore, kyphoplasty seems to be reasonable procedure for osteoporotic vertebral body compression fractures when medical treatment fail.

Background Patients having unilateral breast reconstruction often require a second stage procedure on the contralateral breast to improve symmetry. In order to provide immediate symmetry and minimize the frequency and extent of secondary procedures, we began performing simultaneous contralateral balancing operations at the time of initial reconstruction. This study examines the indications, safety, and efficacy of this approach. Methods One-hundred and two consecutive breast reconstructions with simultaneous contralateral balancing procedures were identified. Data included patient age, body mass index (BMI), type of reconstruction and balancing procedure, specimen weight, transfusion requirement, complications and additional surgery under anesthesia. Unpaired t-tests were used to compare BMI, specimen weight and need for non-autologous transfusion. Results Average patient age was 48 years. The majority had autologous tissue-only reconstructions (94%) and the rest prosthesis-based reconstructions (6%). Balancing procedures included reduction mammoplasty (50%), mastopexy (49%), and augmentation mammoplasty (1%). Average BMI was 27 and average reduction specimen was 340 grams. Non-autologous blood transfusion rate was 9%. There was no relationship between BMI or reduction specimen weight and need for transfusion. We performed secondary surgery in 24% of the autologous group and 100% of the prosthesis group. Revision rate for symmetry was 13% in the autologous group and 17% in the prosthesis group. Conclusions Performing balancing at the time of breast reconstruction is safe and most effective in autologous reconstructions, where 87% did not require a second operation for symmetry.

공기주입 정복술(pneumatic reduction) 및 방사선 배뇨성 방광요도 조영술(Voiding Cystourethrography: 이하 VCUG)는 일반적으로 영,유아에게서 행해지는데 이들 검사는 투시촬영과 spot 촬영으로 이루어지며 이때 투시촬영으로 인한 방사선 피폭은 불가피한 것이나 spot 촬영으로 인한 피폭은 투시 화면상의 관심영상을 capture하는 기능인 fluorograb을 이용하여 제거할 수 있다. fluorograb은 spot영상과 비슷한 진단가치를 지니고 있으며 최근 사용되고 있는 대부분의 투시촬영장비에서 지원되는 기능이지만 다수의 의사 및 방사선사는 이 기능을 인지하지 못하고 있거나 인지하고는 있으나 습관적으로 spot 촬영을 행하고 있는 실정이다. 이는 방사선에 매우 민감한 연령대에 속한 영.유아에서 적게는 10장 미만에서 많게는 20장 이상을 spot 촬영하게 되는 공기주입 정복술 및 VCUG에서 그 영향이 적지 않다 하겠다. 따라서 공기주입 정복술 및 VCUG 시행시 spot 촬영으로 인한 영.유아의 피폭을 줄이기 위한 방법으로 spot 촬영을 대신한 fluorograb을 제안하며 이로 인한 기존의 공기주입 정복술 및 VCUG 시행 시 영 유아의 피폭선량 경감 효과를 증명하고자 하였다. 공기주입 정복술 및 VCUG 의 진단에 fluorograb은 spot 촬영과 비슷한 수준의 정확도를 보이는 안전하고 유용한 방법이여 공기주입 정복술 및 VCUG 시행 시 spot 촬영을 대체할 수 있을 것으로 생각한다.

Purpose: The impact of coronavirus 2019 (COVID-19) on gastrointestinal (GI) endoscopy procedures in adults has been reported, with a drastic reduction in the number of procedures. However, there are no sufficient data regarding the impact on pediatric GI endoscopy. Here, we aimed to report that impact in the Asia-Pacific region. Methods: A questionnaire-based internet survey was conducted from June to November 2021 among pediatric endoscopy institutions in the Asia-Pacific region, with each institution providing a single response. Overall, 25 questions focused on the impact of the number of procedures conducted, the usage of personal protective equipment (PPE), and endoscopy training programs during the pandemic. Results: A total of 162 institutions across 13 countries in the Asia-Pacific region participated in the study, and 133 (82.1%) institutions underwent procedure changes since the emergence of COVID-19. The number of esophagogastroduodenoscopy and ileocolonoscopy procedures decreased in 118/133 (88.7%) and 112/133 (84.2%) institutions, respectively. Endoscopy for patient with positive COVID-19 in an emergency or urgent cases still carried out in 102/162 (62.9%) institutions. Screening of COVID-19 for all patients before endoscopy was done across 110/162 (67.9%) institutions. PPE recommendations varied among institutions. Pediatric gastrointestinal endoscopy training programs were discontinued in 127/162 (78.4%) institutions. Conclusion: This study reports the impact of the COVID-19 pandemic on pediatric gastrointestinal endoscopy in the Asia-Pacific region. There has been a significant reduction in the number of endoscopic procedures and relevant training programs.

We developed lead gloves that minimize radiation dose to the operator's hands during interventional radiological procedures and that do not impede the operator's surgical capabilities. Existing lead gloves can protect the operator's hands by shielding radiation, but use of such gloves may impair preception sensitivity, resulting in a reduction in the operator's surgical ability. Accordingly, in this study, we developed modified lead gloves that can reduce radiation dose while maintaining operator sensitivity during procedures by modifying the operator's main surgical finger area in existing lead gloves. To evaluate the performance of developed modified lead gloves, radiation was applied in surgical conditions without gloves and with surgical gloves, lead gloves, and modified lead gloves. The radiation dose was evaluated for each condition. When the modified lead gloves were worn, the degree of shielding was similar to when conventional lead gloves were worn. Based on these results, if the operator wears modified lead gloves during interventional radiological procedures, they will protect the hands from radiation while maintaining physical sensitivity in the hands.

Objective : Bone cement augmentation procedures such as percutaneous vertebroplasty and balloon kyphoplasty have been shown to be effective treatment for acute or subacute osteoporotic vertebral compression fractures. The purpose of this study was to determine the efficacy of bone cement augmentation procedures for long standing osteoporotic vertebral compression fracture with late vertebral collapse and persistent back pain. Methods : Among 278 single level osteoporotic vertebral compression fractures that were treated by vertebral augmentation procedures at our institute, 18 consecutive patients were included in this study. Study inclusion was limited to initially, minimal compression fractures, but showing a poor prognosis due to late vertebral collapse, intravertebral vacuum clefts and continuous back pain despite conservative treatment for more than one year. The subjects included three men and 15 women. The mean age was 70.7 with a range from 64 to 85 years of age. After postural reduction for two days, bone cement augmentation procedures following intraoperative pressure reduction were performed. Imaging and clinical findings, including the level of the vertebra involved, vertebral height restoration, injected cement volume, local kyphosis, clinical outcome and complications were analyzed. Results : The mean follow-up period after bone cement augmentation procedures was 14.3 months (range 12-27 months). The mean injected cement volume was 4.1 mL (range 2.4-5.9 mL). The unipedicular approach was possible in 15 patients. The mean pain score (visual analogue scale) prior to surgery was 7.1, which decreased to 3.1 at 7 days after the procedure. The pain relief was maintained at the final follow up. The kyphotic angle improved significantly from $21.2{\pm}4.9^{\circ}$ before surgery to $10.4{\pm}3.8^{\circ}$ after surgery. The fraction of vertebral height increased from 30% to 60% after bone cement augmentation, and the restored vertebral height was maintained at the final follow up. There were no serious complications related to cement leakage. Conclusion : In the management of even long-standing osteoporotic vertebral compression fracture for over one year, bone cement augmentation procedures following postural reduction were considered safe and effective treatment in cases of non-healing evidence.
