Pediatric kidney disease has a relatively lower prevalence than do other pediatric conditions and has a notably different etiology from kidney diseases observed in adults. Furthermore, the pediatric population is unique in that they experience ongoing growth and development, distinguishing them from adult patients. Consequently, pediatric patients with kidney disease require more specialized and meticulous nutritional management than do adults. To address this need and promote optimal dietary practices for pediatric patients with kidney disease, pediatric nephrologists from the Korean Society of Pediatric Nephrology and nutritionists from the Korean Society of Clinical Nutrition have collaborated to establish nutritional guidelines specifically tailored to Korean dietary patterns. These guidelines offer detailed, nutrient-specific recommendations covering energy, protein, calcium, phosphorus, and potassium consumption while providing practical, culturally relevant guidance intended to support both pediatric patients and their caregivers.

Endoscopic mucosal resection (EMR) and endoscopic submucosal dissection (ESD) with submucosal saline injection are well-established methods for excising nonpolypoid early neoplastic lesions of the gastrointestinal tract in humans. In EMR and ESD, this submucosal injection forms a bulla that lifts the lesion, provides a safety cushion during resection, and reduces the risk of perforation. Commonly used solutions include normal saline (NS), 10% glycerol, and 0.4% sodium hyaluronate (SH). Among these, 0.4% SH is the most preferred solution in humans due to its slow absorption. While the usefulness of EMR and ESD in humans has been well-documented, information on its application in veterinary medicine remains limited. This study aimed to compare the usefulness and safety of 0.4% SH with 10% glycerol and NS as a gastric submucosal injection solution in rabbits with goals of providing a veterinary perspective on the application of submucosal injection solutions and highlighting the clinical relevance for endoscopic procedures in animals. A conventional gastrotomy was performed to expose the gastric lumen, followed by a submucosal injection. In macroscopic evaluations of mucosal elevation using a digital caliper, 0.4% SH showed a statistically significant elevation effect compared with NS, unlike 10% glycerol. Histomorphometric analysis further revealed that 0.4% SH maintained submucosal space expansion for the longest duration. In addition, histopathological analysis showed no tissue damage except for hemorrhage across all of the submucosal injection groups. In conclusion, 0.4% SH is considered the most preferable submucosal injection material in veterinary medicine, particularly for its usefulness and safety. Based on the results of this study, minimally invasive techniques such as EMR and ESD are expected to be applicable in animals. This study provides the first veterinary-specific evaluation of 0.4% SH as a submucosal injection solution in endoscopic resection (ER), demonstrating its potential benefits in minimally invasive endoscopic procedures. The findings suggest that 0.4% SH may enhance the safety and efficacy of ER, making it a preferable choice for submucosal injection in this context in veterinary medicine.

Objectives: We evaluated the efficacy of a medial arthroscopic approach to the coxofemoral joint of dogs by analyzing the joint visible area and performing a safety analysis. Methods: Arthroscopic approaches to the coxofemoral joint were made in five cadavers using a traditional (dorsal) and novel (medial) approach. Three observers scored the visible area of images and videos of the acetabulum and femur. A safety analysis was performed via dissection of the medial hind limb. The distance between neurovascular structures and arthroscopic portals was measured. Results: The acetabulum was more visible in the dorsal than in the medial approach, with mean visualization scores of 16 ± 0.00 and 11.83 ± 1.26, respectively. The medioventral side of the femur was significantly more visible in the medial than in the dorsal approach, with mean visualization scores of 3.9 ± 0.99 and 6.93 ± 0.58, respectively. Safety analysis confirmed the medial portal site was safe, provided that the surgeon has comprehensive knowledge of the joint. The minimum distance from the arthroscopic medial portals to the nearest neurovascular structures was 2.5 mm. Conclusions A medial arthroscopic approach to the canine coxofemoral joint has potential clinical application. Dorsal and medial approaches differ significantly and have distinct purposes. The medial approach is useful to access the ventromedial joint, making it an eligible diagnostic method for an arthroscopic evaluation of this area.

Abstract: Ten cadavers were studied to compare the accessibility of cervical vertebral canal with conventional standard ventral slot and modified slanted ventral slot. One group performed standard ventral slot procedures at the C3-4, C5-6. The other group performed modified slanted ventral slot with inverted cone technique procedures at the C3-4, C5-6 computed tomography was performed before and after surgery. The accessibility of cervical vertebral canal with conventional standard ventral slot and modified slanted ventral slot using computed tomography in C3-4 and C5-6 intervertebral space was compared. Although smaller ostectomy was performed in the modified slanted ventral slot, some lesions were more accessible but limitations were obvious in C3-4 and C5-6 intervertebral disk space. After the disc material has been identified through accurate preoperative diagnostic imaging, less morbidity and complications can be expected if the appropriate surgical method is selected based on the lesion of compression.

Background: Tibial tuberosity transposition (TTT) causes caudalization of the patellar ligament insertion in canine medial patellar luxation, which can lead to increases in patellofemoral contact pressure. Objectives: The purpose of this study is to confirm the effect of patellofemoral contact mechanics after craniolateral and caudolateral transposition of tibial tuberosity in normal canine hindlimbs. Methods: Craniolateral and caudolateral transposition of tibial tuberosity was performed in 5 specimens, respectively. The pressure was measured in the specimen before TTT, and then in the same specimen after TTT. In this process, data was obtained in 10 specimens. The measurement results were output as visualization data through the manufacturer's software and numerical data through spreadsheet. Based on these 2 data and the anatomical structure of the patellofemoral joint (PFJ) surface, whole measurement area was analysed by dividing into medial, lateral and central area. Results: In craniolateralization of tibial tuberosity, total, medial, central contact pressure was decreased and lateral contact pressure was not statistically changed lateral contact pressure than normal PFJ. In caudolateralization of tibial tuberosity, total, lateral contact pressure was increased and medial contact pressure was not statistically changed than normal PFJ. Although not statistically significant changed, central contact pressure in caudolateralization of tibial tuberosity was increased in all 5 specimens. Conclusions These results imply that traditional TTT, prone to caudal shift of patellar tendon, can increase retropatellar pressure may lead to various complications and diseases of the stifle joint.

A 37-year-old woman underwent a total mastectomy and adjuvant chemotherapy for HER2-positive breast cancer (pT1N0M), and then recurred in the right lung followed by the pancreas. Lung lobectomy and pylorus-preserving pancreaticoduodenectomy were performed, and systemic chemotherapies including trastuzumab were sequentially administered. However, metastasis to the pancreatic tail was detected. She underwent image-guided radiation therapy, but this was not effective. Lapatinib plus capecitabine combination was administered as forth-line treatment and the metastatic lesion was disappeared. She is continuing this regimen with a complete response for 48 months until now.

We developed age, gender and ethnic specific brain templates based on MR and Positron-Emission Tomography (PET) images of Korean normal volunteers. Seventy-eight normal right-handed volunteers (M/F=49/29) underwent 3D T1-weighted SPGR MR and F-18-FDG PET scans. For the generation of standard templates, an optimal target brain that has the average global hemispheric shape was selected for each gender. MR images were then spatially normalized by linear transformation to the target brains, and normalization parameters were reapplied to PET images. Subjects were subdivided into 2 groups for each gender: the young/midlife (<55 yr) and the elderly groups. Young and elderly MRI/PET templates were composed by averaging the spatially normalized images. Korean templates showed different shapes and sizes (mean length, width, and height of the brains were 16.5, 14.3 and 12.1 cm for man, and 15.6, 13.5 and 11.4 cm for woman) from the template based on Caucasian (18.3, 14.2, and 13.3 cm). MRI and PET templates developed in this study will provide the framework for more accurate stereotactic standardization and anatomical localization.
