  • Intellectual disability (ID) is the most common disability among people under the age of 20 years. In the absence of obvious non-genetic causes of ID, the majority of cases of severe ID are thought to have a genetic cause. The advent of technologies such as array comparative genomic hybridization, single nucleotide polymorphism genotyping arrays, and massively parallel sequencing has shown that de novo copy number variations and single nucleotide variations affecting coding regions are major causes of severe ID. This article reviews the genetic causes of ID along with diagnostic approaches for this disability.

  • Leucine rich repeat kinase 2 (LRRK2) is a highly promising target for Parkinson's disease (PD) that affects millions of people worldwide. A three-dimensional quantitative structure-activity relationship (3D-QSAR) analysis was performed on a series of pyrrolopyrimidine-based selective LRRK2 kinase inhibitors. This study was performed to rationalize the structural requirements responsible for the inhibitory activity of these compounds. A reliable 3D-QSAR model was developed using comparative molecular field analysis (CoMFA) technique. The model produced statistically acceptable results with a cross-validated correlation coefficient ($q^2$) of 0.539 and a non-cross-validated correlation coefficient ($r^2$) of 0.871. Robustness of the model was further evaluated by bootstrapping and progressive scrambling analysis. This work could assist in designing more potent LRRK2 inhibitors.

  • The application of ultrasound (US) in pain medicine has been a rapidly growing field since the 2000s. Musculoskeletal injections, peripheral nerve blocks, and neuraxial injections under US guidance have been acknowledged for managing chronic pain. Although many studies on US-guided pain procedures have been published, there needs to be a classification system to evaluate which image device, the US or fluoroscopy, is clinically and technically better in various pain interventions. Therefore, this narrative review introduces the classification system for the US-guided pain procedures according to their clinical and technical outcomes and designates US-guided pain procedures into one of the four categories by reviewing previous prospective randomized comparative trials.

  • First I chose a patient group and a comparative group composed of 23 members each. Then the body temperature differences in these groups was taken with D.I.T.I. The results are as follows. 1. Average body temperature of the Hwa-Byung patient group is $36.6^{\circ}C$ and that of the comparative group is $36.4^{\circ}C$. So there is no meaningful body temperature difference. 2. The hwa-Byung patient group has higher temperature than the comparative group by ${\triangle}T>1.0^{\circ}C$ at the following acupunture points in these body parts upper and lower, left and right, anterior and posterior, trunk and limb. Especially, the body temperature difference was clear in the CV-17 (jun-Joong) and the GV-4(Myung-moon). 3. When the body temperature was compared in the upper and lower part of the back, it had meaningful differences at the upper and lower acupunture points of the back in the Hwa-Byung patient group but not in the comparative group. 4. When the body temperature was compared in the left and right part of the body, its average difference was ${\triangle}T>1.0^{\circ}C$ in the two groups and the result were meaningless. 5. When body temperature was compared in the anterior and posterior part of the body, its average difference was ${\triangle}T>1.0^{\circ}C$ in the two groups and the result were meaningless. 6. When body temperature was compared in the trunk and limb part of the body, its difference in the patient group was meaningful compared with the non-patient group. From the above results, I think that D.I.T.I. could be used to objectively visualize heat sensation of the Hwa-Byung patients and make an objective concept of Han Yul in oriental medicine.

  • Objectives: The purpose of this study is to analyze the current state of quantitative literature evidence for the prescription of 56 herbal medicines covered by health insurance that have been studied in Korea for the past 30 years, to evaluate the reliability of the evidence, and to find out the research direction of herbal medicine prescription in the future. Methods: 56 kinds of herbal medicine prescriptions were searched in domestic literature search databases OASIS, DBpia, and overseas PubMed, classified into chemistry, toxicity, cells, animals, clinical cases, and clinical trial studies, and built into an EBM pyramid structure. Results: When classified according to research contents, there were 61 cases (7.5%) of physicochemical analysis to identify constituent substances, 80 cases (9.8%) of toxicity evaluation, and 672 cases (82.7%) of efficacy evaluation. The efficacy evidence was classified according to the evidence-based medical pyramid structure: 196 cell trials (29.1%), 372 animal trials (55.4%), 89 case and case reporting series (13.3%), 7 comparative case studies (1.1%), and 8 randomized control clinical trials (1.2%). In the pyramid composition, the basis for the validity of 56 kinds of herbal medicines prescribed was 568 cases (84.5%) in cell and animal units, which could not be said to be highly reliable. There was no relationship between the ranking of quantitative literature evidence for herbal medicine prescriptions and the ranking of salary administration. Conclusions: In an era that continues to require scientific evidence for herbal medicine, traditional herbal medicine should secure the basis for safety validity even for the 10th most frequent prescription among 56 herbal medicine prescriptions for consumers. In particular, traditional herbal medicine should increase the quantitative and qualitative level of case reports on related herbal medicine prescriptions, focusing on each clinical society, and move toward comparative case studies and randomized clinical trial so that traditional herbal medicine is positioned as Evidence-based medicine.

  • Concentrations of cortisol, dehydroepiandrosterone and dehydroepiandrosterone-sulfate were measured by performing radioimmunoassay of the cerebrospinal fluid of 68 dogs diagnosed with idiopathic epilepsy or inflammatory, degenerative, or non-neurological disease. No steroid concentration differences were found among diagnoses. Dehydroepiandrosterone and dehydroepiandrosterone-sulfate concentrations were higher in males than in females and dehydroepiandrosterone-sulfate decreased with increasing age. No sex or age effects were observed on cortisol or hormone ratios. Although limited to a relatively small sample, our results show sex- and age-dependent variations in these neurosteroid concentrations in cerebrospinal fluid. The role of such variations in the pathophysiology of the dog brain warrants further investigation.

  • In patients with unilateral condylar hyperplasia, increased length of the condylar neck causes deviation of the mandible to the opposite site, resulting in facial asymmetry, but the arch form and general contour of the displaced mandible is approximately symmetric. So, the unilateral condylectomy have been prefered surgical method among the surgeons. The purpose of this study is to analyze the postoperative results comparatively following two different surgical methods, condylectomy and ramus surgery, in unilateral condylar hyperplasia. Case of 6 patients with the unilateral condylar hyerplasia were analyzed in this study, 3 case of the condylectomy only, 3 cases of the ramus surgery, Clinical and radiographic evaluations were tried for comparison. In conclusion, comparative results between two groups did not show any significant difference, but we confirmed that unilateral condylectomy could be a excellent surgical methods in unilateral condylar hyperplasia thinking over the unique morphological characteristics of it.
