척추 신경 차단술은 다양한 발전을 거듭하면서 상당부분 수술적 치료의 필요성을 줄일 수 있는 대체 보존적 치료의 한 방법으로 자리매김하고 있다. 이러한 척추 신경 차단술은 통증 완화라는 치료적 측면뿐 아니라, 많은 환자에서 척추 이외의 다른 증상들과 감별을 위한 진단적 목적으로도 유용하게 사용되고 있어 사지 및 척추를 다루는 정형외과의사로서 가장 기본이 되는 술기라 할 수 있다. 하지만 사용하는 기구나 약물이 단순함에도 불구하고 이에 대한 전반적인 이해 및 발생 가능한 부작용 및 합병증에 대한 지식이 없다면 시행 초기에 오히려 환자에게 심각한 해를 끼칠 수 있게 된다. 따라서 척추 신경 차단술에 사용하는 약제들의 종류, 약동학적 특성과 각각 약제의 부작용에 대한 이해가 선행되어야 하며, 요추 전반에 걸친 각 시술의 적응증과 장단점을 파악하고 발생 가능한 합병증을 피하기 위해 노력을 기울여야 한다. 본 종설은 요추 신경 차단술에 필요한 기본적인 지식 및 술기를 접하여 독자 스스로 시행할 수 있게 함을 목적으로 한다.

To evaluate the effectiveness of electroacupuncture treatment for primary dysmenorrhea (PD), a literature review of a randomized controlled trials (RCTs) was performed where electroacupuncture was used as a treatment intervention in patients diagnosed with PD. Relevant clinical studies (N = 226) were retrieved from multiple databases according to the study inclusion/exclusion criteria, and interventions and outcomes were analyzed. As a result of the review, there were 6 RCTs which met the criteria. In all 4 studies that measured pain indicators (visual analog scales), electroacupuncture showed significantly positive changes. In addition, positive changes were observed in most indicators (MMDQ, PGF2a, PGE2, 6-keto PGF1, TXB2, clinical efficacy score, uterine arterial blood flow parameters, and blood viscosity). 2 studies showed that electroacupuncture had a stronger therapeutic effect than NSAIDs. No major side effects were reported. Electroacupuncture may be an effective and safe treatment for PD however, further RCTs are required.

Radiofrequency ablation (RFA) is an alternative treatment for liver cancer to the surgical intervention preferred by surgeons. However, the main challenge remains the use of RF for the ablation of large tumours (i.e., tumours with a diameter of >3 cm). For large tumours, RFA takes a large duration in the ablation process compared with surgery, which increases patient pain. Therefore, RFA for large tumours is not preferred by surgeons. The currently materials used in RF electrodes, such as the nickeltitanium alloy (nitinol), are characterized by low thermal and electrical conductivities. On the other hand, the use of materials that have high thermal and electrical conductivities, such as titanium aluminide alloy (gamma titanium), produces more thermal energy for tumours. In this paper, we developed a cool-tip RF electrode model that uses nickel-titanium alloy and replaced it with titanium aluminide alloy by using the finite element model (FEM). The aim of this paper is to study the effect of the thermal and electrical conductivities of gamma titanium on the ablation volume. Results showed that the proposed design of the electrode increased the ablation rate by 1 cm³ /minute and 6.3 cm³/10 minutes, with a decrease in the required time ablation. Finally, the proposed model reduces the ablation time and damages healthy tissue while increasing the ablation volume from 22.5% cm³ to 62.5% cm³ in ten minutes compared to recent studies.

Objectives This study aimed to investigate the clinical trial trends of Chuna manual therapy (CMT) on gynecologic disease and suggest the effectiveness and safety evidence for further study. Methods We searched nine electronic databases (CENTRAL, CiNii, CNKI, EMBASE, KMbase, KISS, MEDLINE PubMed, NDSL, and OASIS) using the search terms "Chuna" and "Tuina" and identified relevant literature that investigated the CMT as an intervention for gynecologic disease. All relevant papers were extracted and selected to be analyzed. Results Among the 1456 studies that were searched and screened, 18 randomized controlled trials (RCTs) satisfied the designated criteria. A meta-analysis showed that CMT had a curative effect on patients with primary dysmenorrhea, postpartum hypogalactia, breast hyperplasia, postpartum urinary retention, and pelvic pain. Conclusions Based on this study, CMT should be comprehensively considered for gynecologic disease. The treatment response was significantly enhanced after treatment; however, there were some limitations in the study. More well-designed RCTs are needed to ensure that all gynecologic patients have a safe and effective therapy.

Background: The purpose of this study is to analyze the effect of shoulder and neck stabilization exercise using a gym ball for healthy women in their 20s with round shoulder and forward head posture, it is intended to try and find improvement for posture. Methods: The subjects of the study were 25 women who understood the purpose of the research and voluntarily agreed to participate in the experiment. They carried out the shoulder and neck stabilization exercise program using a gym ball, which was conducted for 35 minutes, 3 times a week for 4 weeks. The position of the round shoulder and shoulder bones was measured using an tape measurement and were recorded in both at pre, 2 weeks, and post intervention. The craniovertebral angle (CVA) and craniorotational angle (CRA) was measured using an image J. Results: The round shoulder posture left was statistically significantly different within group (p<.05); however, the round shoulder posture right wasn't statistically significantly different (p>.05). As a result of this contrast, test were significant different in both at pre, 2 weeks and post. The scapular position on the left and right were statistically significantly different within the group (p<.05). As a result of the contrast, test were significant different in both at pre, 2 weeks and post (p<.05). The CVA and CRA on the left and right were statistically significantly different within the group (p<.05). As a result of the contrast, test were significant different in both at pre, 2 weeks and post (p<.05). Conclusion: The gym ball exercises improved the posture of women in their 20s. Therefore, gym ball exercises can help improve the quality of life of those with shoulder and neck pain.

Purpose: We evaluated the status of patients enrolled in South Korea's pediatric palliative care pilot project based on the experience of a single center. This study examined factors related to end-of-life services and differences in medical costs. Methods: The medical records of 120 patients referred by a pediatric palliative care team were analyzed retrospectively. Data from July 1 to February 28, 2022 were collected and analyzed using the chi-square test and the Mann-Whitney U test. Results: Volunteer programs and psychological support (100%), family support and education (99.2%), and financial support through institutional linkage (62.5%) were provided to the participants. In the deceased group, there were no significant differences in general characteristics, which included age, gender, primary disease, religion, duration of hospitalization in an intensive care unit (ICU) and non-intensive care unit (non-ICU). However, the ICU group had fewer opportunities to access individual pain and physical symptom management than the non-ICU group and there were limitations in linking with external resources. Medical expenses were significantly different for the ICU group, with a 3-times higher average cost than the non-ICU group. Conclusion: Although an individualized approach is needed for each patient in pediatric palliative care, psychosocial care is essential. In addition, if early intervention for end-of-life pediatric patients is available from a palliative care team, the cost burden of medical care for patients and their families should be minimal.

Objectives: An ectopic tooth is a rare eruption of a tooth out of the normal dental apparatus and occurs commonly with the third molar. Thus, in this study, we reported a case series of ectopic teeth in rare jaw locations and highlight the associated pathology and our experience in the surgical management. Patients and Methods: All cases of ectopic tooth managed at the Department of Oral and Maxillofacial Surgery, University of Maiduguri Teaching Hospital from January 2011 to December 2020 were reviewed. The information retrieved includes biodata, location of the ectopic tooth, signs, symptoms, type of tooth and associated pathology, surgical approach and complications. Results: Ten cases of ectopic teeth were identified over the study period. This comprised 80.0% males with a mean age was 23.3 years. The antrum and lower border of the mandible accounted for 50.0% and 40.0% of the ectopic locations, respectively. Dentigerous cyst was the most associated pathology (70%) and usually presented with pain and swelling. Surgical intervention predominantly via the intraoral route was performed if indicated. Conclusion: Ectopic teeth are rare and not always associated with pathology. A high index of suspicion and radiological investigation are necessary for diagnosis. A more extensive multi-center study is however recommended to determine the prevalence of ectopic teeth other than the third molar.
