This study reports on diffuse leptomeningeal glioneuronal tumor (DL-GNT) in a 29- year-old male. DL-GNT is a rare central nervous system (CNS) tumor mostly seen in children and only few cases have been reported in adult patients. Our patient presented with a chronic headache that lasted for five months. MR imaging showed mild hydrocephalus, multiple rim-enhancing nodular lesions in the suprasellar cistern, diffuse leptomeningeal enhancement in the lumbosacral area, and multiple small non-enhancing cyst-appearing lesions not suppressed on fluid attenuated inversion recovery (FLAIR) images in the bilateral basal ganglia, thalami, and cerebral hemispheres. Under the impression of germ cell tumor with leptomeningeal seeding, the patient underwent trans-sphenoidal tumor removal. DL-GNT was pathologically confirmed and FGFR1 mutation was detected through a next-generation sequencing test. In conclusion, a combination of leptomeningeal enhancement and multiple parenchymal non-enhancing cyst-appearing lesions not suppressed on FLAIR images may be helpful for differential diagnosis despite overlapping imaging features with many other CNS diseases that have leptomeningeal enhancement.

A 58-year-old woman presented with right flank and back pain for one month. After undergoing an abdominal computed tomography (CT), she was referred to our hospital. The abdominal CT showed a hypodense pancreatic tail mass with multiple retroperitoneal lymph node metastases. Positron emission tomography-computed tomography (PET-CT) scan showed high 18F-FDG uptake in pancreatic tumor and enlarged lymph nodes. Endoscopic ultrasound fine needle aspiration (EUS-FNA) revealed adenocarcinoma, which stained strongly in hENT1 (human equilibrative nucleoside transporter 1) on immunohistochemistry. She received gemcitabine 1,000 mg/m² + nanoparticle albumin-bound paclitaxel 125 mg/m² as a palliative chemotherapy. Follow-up abdominal CT and PET-CT after 4 cycles of chemotherapy showed that both pancreatic mass and the metastatic retroperitoneal lymph nodes were nearly disappeared. We report a case of 58-year-old female with metastatic pancreatic cancer who had a dramatic response to palliative chemotherapy (gemcitabine plus nanoparticle albumin-bound paclitaxel).

Purpose: This study's aim was to confirm the importance and performance of the clinical practice of nurses working in the general wards of a tertiary hospital and to analyze their educational needs. Methods: The study employed a descriptive research design, and a self-reported questionnaire was developed and used for nurses in a tertiary hospital. Data were collected from July 22 to July 29, 2022, analyzed by an independent t-test, paired t-test, and one-way ANOVA for the importance and performance of each clinical nursing practice according to general characteristics, and then a post hoc verification was performed by Scheffé's test. An Importance-Performance Analysis and Borich needs assessment model were used to analyze clinical nursing education needs. Results: Clinical nursing practice performance showed a significant difference according to length of total clinical career, time working in current department, and preceptor experience. According to the results of the Importance-Performance Analysis, neurological evaluation, and nursing intervention, artificial respirator and high-flow oxygen inhalation nursing, chemotherapy, emergency nursing, and cardiopulmonary resuscitation were identified as belonging to the "concentrate here" quadrant. All these items ranked in the top 10 in the Borich needs assessment model. Conclusion: Based on these results, the current education system should be reviewed, and short and long term education strategies based on educational needs should be established to strengthen the competence of nurses.

Primary rectal syphilis is a rare disease that can be misdiagnosed as lymphoma or other rectal cancers on sigmoidoscopy or CT. Here, we report a case of primary rectal syphilis mimicking rectal malignancy in a 23-year-old male who presented with a rectal mass and multiple lymphadenopathies. In this case report and literature review, we focused on the CT findings and endoscopic observations of primary rectal syphilis. Infectious diseases, such as rectal syphilis, should be considered in the differential diagnosis of young patients with unusual rectal lesions and disproportionately extensive lymphadenopathies.

Purpose: The purpose of this study is to confirm the effect of resilience, family support, and spiritual well-being on posttraumatic growth(PTG) in lung cancer patients undergoing chemotherapy. Methods: The study collected data from January 20 to July 6, 2023 on 124 lung cancer patients who were admitted to hospital of C university in Seoul and received chemotherapy treatment. Patients were asked to complete a questionnaire consisting of general characteristics, disease characteristics, resilience, family support, spiritual well-being and PTG. Data were analyzed using t-tests, One-way ANOVA, Pearson's correlation and multiple regression analysis. Results: The mean score for PTG in lung cancer patients was 55.17, resilience was 72.46, family support was 49.00, and spiritual well-being was 53.50. Significant positive correlations were found for PTG with resilience (r=.62, p<.001), family support (r=.40, p<.001) and spiritual well-being (r=.47, p<.001). Factors contributing to PTG of lung cancer patients were resilience (β=.50, p<.001), spiritual well-being (β=.20, p=.008), and gender (β =.14, p=.043). Conclusion: This study aims to provide basic data for the PTG intervention program by identifying factors affecting the PTG of lung cancer patients. It is necessary to develop new nursing intervention programs to improve PTG for patients with lung cancer based on strategies to enhance resilience and spiritual well-being.

Purpose In the adult emergency department of a university hospital, we investigated the frequency of major discrepancies between the preliminary reports by radiology residents and the final reports by certified radiologists. Materials and Methods Based on CT and MRI scans obtained between December 2016 and November 2019, we selected cases with diagnoses or treatment plans that could be changed due to discrepancies between preliminary and final reports and classified them by the type of discrepancy. We also examined the distributions of the major discrepancies and stratified them by residents' working time zone, experience, and subspecialty. Results Based on the 72137 preliminary reports evaluated, 1348 tests (1.9%) showed major discrepancies. Most of the major discrepancies were false negatives (72.0%), followed by misdiagnosis (26.3%) and false positives (1.7%). Acute findings (87.2%) were more common than non-acute findings (12.8%). The major discrepancy rate increased toward the second half of the 24-hour shift, with the highest rate of 2.9% occurring between 2 am and 4 am. The major discrepancy rate did not vary with experience, and it varied from 0.6% to 4.5% for each subspecialty. Conclusion The major discrepancy rate was less than 2%, and it increased with longer working hours during a 24-hour shift.

Virtual reality (VR) provides an immersive and interactive 3-dimensional system, which allows an individual to become immersed in a computer-generated situation. VR technology has been administered in the exposure-based treatment of a variety of psychiatric disorders, including acrophobia, fear of flight, and post-traumatic stress disorder. Furthermore, VR systems have also been developed for the use of research and treatment in addiction. They might have advantages in cue exposure therapy, by increasing the salience of cues, as well as assessments of cue reactivity in addiction. This article summarizes the application of VR in the field of psychiatry. More importantly, it suggests the possibilities of clinical use of VR technology, in the treatment of addiction.

Purpose To develop and validate a deep learning-based screening tool for the early diagnosis of scoliosis using chest radiographs with a semi-supervised generative adversarial network (GAN). Materials and Methods Using a semi-supervised learning framework with a GAN, a screening tool for diagnosing scoliosis was developed and validated through the chest PA radiographs of patients at two different tertiary hospitals. Our proposed method used training GAN with mild to severe scoliosis only in a semi-supervised manner, as an upstream task to learn scoliosis representations and a downstream task to perform simple classification for differentiating between normal and scoliosis states sensitively. Results The area under the receiver operating characteristic curve, negative predictive value (NPV), positive predictive value, sensitivity, and specificity were 0.856, 0.950, 0.579, 0.985, and 0.285, respectively. Conclusion Our deep learning-based artificial intelligence software in a semi-supervised manner achieved excellent performance in diagnosing scoliosis using the chest PA radiographs of young individuals; thus, it could be used as a screening tool with high NPV and sensitivity and reduce the burden on radiologists for diagnosing scoliosis through health screening chest radiographs.
