  • Owing to improvements in surgical techniques and medical care, living-donor liver transplantation has become an established treatment modality in patients with end-stage liver disease. However, various vascular or non-vascular complications may occur during or after transplantation. Herein, we review how interventional radiologic techniques can be used to treat these complications.

  • Cervical and thoracic radiculopathies are among the most common causes of neck pain. The most common causes are cervical disc herniation and cervical spondylosis in patients with cervical radiculopathy, and diabetes mellitus and thoracic disc herniation in thoracic radiculopathy. A thorough history, physical examination, and testing that includes electrodiagnostic examination and imaging studies may distinguish radiculopathy from other pain sources. Although various electrodiagnostic examinations may help evaluate radiculopathy, needle electromyography is the most important, sensitive, and specific method. Outcome studies of conservative treatments have shown varying results and have not been well controlled or systematic. When legitimate incapacitating symptoms continue despite conservative treatment attempts, more invasive spinal procedures and intradiscal treatment may be appropriate. Surgery has been shown to have excellent clinical outcomes in patients with disc extrusion and neurological deficits. However, patients with minimal disc herniation have fair or poor surgical outcomes. In addition, conventional open disc surgery entails various inadvertent surgical related risks. Although there has not yet been a non-surgical interventional procedure developed with the therapeutic efficacy of open surgery, conservative procedures can offer substantial benefits, are less invasive, and avoid surgical complications. While more invasive procedures may be appropriate when conservative treatment fails, prospective studies evaluating cervical and thoracic radiculopathies treatment options would help guide practitioners toward optimally cost-effective patient evaluation and care.

  • C-arm fluoroscopy is useful equipment in interventional pain management because it helps to guide correct needle targeting for the accurate injection and drug delivery. However, due to increased use of C-arm fluoroscopy in various pain procedures, the risk of radiation exposure is a significant concern for pain physicians. The harmful biological effects of ionizing radiation on the human body are well known. It is therefore necessary to strive to reduce radiation exposure. Lead aprons with thyroid shields are the most fundamental radiation protective devices for interventional procedures, and are very effective. However, the operator's radiation safety cannot be guaranteed because pain physicians seem to lack sufficient interest, knowledge, and awareness about radiation safety. Also, inappropriate care and use of radiation protective devices may result in a higher risk of radiation exposure. The purpose of this article was to review the literature on radiation safety with a focus on lead aprons and thyroid shields and present recommendations related to those devices during C-arm fluoroscopic-guided interventions by pain physicians.

  • Background: The aim of this study was to assess the role of the presence of a choline peak in 3 Tesla 1H magnetic resonance spectroscopy (MRS) for differentiating benign from malignant adnexal masses. Materials and Methods: A total of 46 adnexal masses (23 malignant and 23 benign) underwent 1H MRS study prior to surgery to assess the presence of choline peak. Results: A choline peak was detected in 16 malignant masses (69.5%) and was absent in the other 7 (30.5%). A choline peak was only detected in 6 (26%) of the benign adnexal masses. The presence of an MRS choline peak had a sensitivity of 69.5%, a specificity of 74%, a positive predictive value (PPV) of 72.7%, and a negative predictive value (NPV) of 71% for diagnosing malignant adnexal masses. A significant difference between the frequency of mean choline peaks in benign and malignant adnexal masses was observed (P value < 0.01). Conclusions: A 1H MRS choline peak is seen in malignant adnexal masses more frequently than the benign masses, and may be helpful for diagnosing malignant adnexal masses.

  • Bronchiolitis obliterans (BO), which is associated with graft-versus-host disease after allogenic hematopoietic stem cell transplantation, is a major obstacle to survival after bone marrow transplantation due to its gradual progress, eventually leading to respiratory failure. Pumpless extracorporeal interventional lung assist (iLA) is effective in treatment of reversible hypercapnic respiratory failure. In this paper, we present a 23-year-old female patient who underwent allogeneic peripheral blood stem cell transplantation (PBSCT) for acute lymphocytic leukemia. After 6 months, she complained of shortness of breath and was diagnosed with BO. Five months later, she developed an upper respiratory tract infection that worsened her BO and caused life-threatening hypercapnia. Since mechanical ventilation failed to eliminate $CO_2$ effectively, iLA was applied as rescue therapy. Her hypercapnia and respiratory acidosis showed significant improvement within a few hours, and she was successfully weaned off iLA after 12 days. This is the first case report of iLA application for temporarily aggravated hypercapnia of PBSCT-associated BO followed by successful weaning. This rescue therapy should be considered in ventilator-refractory reversible hypercapnia in BO patients.

  • The purpose of this paper is to analyze how social supports, such as family, teachers, and friends, affect the school adjustment of children who were abused by their parents, and suggest the interventional solutions in order to improve the social support system and school adjustment. 692 children, aged 4 to 6 in primary schools in Busan, were chosen for the survey and all of them are currently under children's service. Among the respondents, 485 children (70.1%) have experienced abuse, and neglect was the most frequent abuse experienced among them. Neglected children were influenced by teachers, families and friends' support in terms of social support for school adjustments. However, the emotionally abused children were influenced by families, teachers and friends in terms of social support for school adjustments. In addition, children who experienced physical abuse have been influenced by families and teachers'support. Support from friends has no meaning for them. As a result, this paper suggests that an effective interventional solution will be necessary for the school adjustment of abused children. The effective interventional solutions are firstly that neglected children require a high level of attention from their teachers and teachers should encourage parents with parental education and counseling to be helpful for their children. Secondly, emotionally abused children require strong family support through parents'education for child development and caring support programs. Finally, physically abused children need caring programs which develop supportive relationship skills both with parents and teachers for their adjustment in school.
