  • ARC (arthrogryposis multiplex congenita, renal dysfunction and cholestasis) syndrome was first described by Lutz-Richner and Landolt in 1973 and after then similar cases were scarcely reported worldwide. There's no reported case in Korea. It was first suggested that ARC syndrome was inherited by X-linked recessive trait but now it was thought to be inherited by autosomal recessive trait also. Most parents were consanguineous but some unconsanuineous parents were also reported. We report on 1 male and 1 female infant who had ARC syndrome from 2 unrelated families. They were born from unconsanguineous parents.

  • The decrease of metabolism in the brain has been observed as the important lesions of Alzheimer's disease (AD) from the early stages of diagnosis. The cumulative evidence has reported that the failure of mitochondria, an organelle involved in diverse biological processes as well as energy production, maybe the cause or effect of the pathogenesis of AD. Both amyloid and tau pathologies have an impact upon mitochondria through physical interaction or indirect signaling pathways, resulting in the disruption of mitochondrial function and dynamics which can trigger AD. In addition, mitochondria are involved in different biological processes depending on the specific functions of each cell type in the brain. Thus, it is necessary to understand mitochondrial dysfunction as part of the pathological phenotypes of AD according to each cell type. In this review, we summarize that 1) the effects of AD pathology inducing mitochondrial dysfunction and 2) the contribution of mitochondrial dysfunction in each cell type to AD pathogenesis.

  • The mitochondria is the major cellular organelle of energy metabolism for the supply of cellular energy; it also plays an important role in controlling calcium regulation, reactive oxygen species (ROS) production, and apoptosis. Mitochondrial dysfunction causes various diseases, such as neurodegenerative diseases, Lou Gehrig's disease, cardiovascular disease, mental disorders, diabetes, and cancer. Most of the diseases are age-related diseases. In this review, we focus on the roles of mitochondrial dysfunction in cancer. Mitochondrial dysfunction induces carcinogenesis and is found in many cancers. The factors that cause mitochondrial dysfunction differ depending on the types of carcinoma, and those factors could cause cancer malignancy, such as resistance to therapy and metastasis. Mitochondrial dysfunction is caused by a lack of mitochondria, an inability to provide key substances, or a dysfunction in the ATP synthesis machinery. The main factor associated with cancer malignancy is mtDNA depletion. Mitochondrial dysfunction would leads to malignancy through changes in molecular activity or expression, but it is not known in detail which changes lead to cancer malignancy. In order to explore the relationship between mitochondrial dysfunction and cancer malignancy in detail, mitochondria dysfunctional cell lines are constructed using chemical methods such as EtBr treatment or gene editing methods, including shRNA and CRISPR/Cas9. Those mitochondria dysfunctional cell lines are used in the study of various diseases caused by mitochondrial dysfunction, including cancer.

  • Recently, with increasing the number of patients with head injury and cerebrovascular accident, there has been an increasing need for the useful assessment tools of brain dysfunction and it's localization. With the advances in the neuroscience since the mid-1970s, particularly in the areas of neuroanatomical tracing, neuroimaging, and improved behavioraltest design, it has been possible to develop a more precise understanding and localization of brain dysfunction. However, these equipments are not readily available in the private clinics and too expensive to use as a screening tool to all suspected patients with brain dysfunction. Although several screening tests such as Mini-Mental States Examination(MMSE) or Brief Cognitive Rating Scale(BCRS) are simple in use and useful for the brief assessment of brain dysfunction, these are also limited in using for localization of brain dysfunction because of their simplicity. With increasing need of the assessment tool which is able to localize the dysfunction more precisely in the clinical practice, we planned to develop the new assessment tool, the Bedside Neurocognitive Function Localization Test(BNLT) which is suitable for this purpose. The BNLT was designed to be utilized for localizing brain dysfunction effectively and readily in the clinical practice. We introduced the whole process of designing the BNLT in this manuscript.

  • The author investigated the Pantronic PRI scores for detection of TMJ dysfunction using the Pantronic in 20 subjects who were male students of the school of dentistry, Seoul National University selected according to sampling criteria and came to the following conclusions. 1. According to the HDI, 20 subjects were divided into 2 groups, the DiO and the DiI, it was appeared that 45% of the subjects had some degree of TMJ dysfunction in each session. 2. According to the P-PRI, 20 subjects were categorized into 3 categories, the none, the slight and the moderate, it was appeared that 82% of the subjects had some degree of TMJ dysfunction in each session. 3. The ability of the P-PRI was more sensitive than that of the HDI in detection of TMJ dysfunction (p < 0.01). 4. The P-PRI scores were consistent within each session and among sessions. 5. The results suggested that the P-PRI, a measure of reproducibility of border tracings, could be an aid to detect TMJ dysfunction and could be used to assess the severity of TMJ dysfunction.

  • Background: Cardiac dysfunction patients have long been considered at high risk of reintubation. However, it is based on past studies in which only conventional oxygen therapy was applied after extubation. We investigated association between cardiac dysfunction and reintubation rate in situation where high-flow nasal cannula (HFNC) was widely used during post-extubation period. Methods: We conducted a retrospective observational cohort study of patients treated with HFNC after planned extubation in medical intensive care unit of single tertiary center. Patients were divided into normal function group (ejection fraction [EF] ≥45%) and cardiac dysfunction group (EF <45%). The primary outcome was reintubation rate within 72 hours following extubation. Results: Of 270 patients, 35 (13%) had cardiac dysfunction. Baseline characteristics were similar in both groups. There were no differences in the changes in vital signs between the two groups during the first 12 hours after extubation except diastolic blood pressure. The reintubation rates were 20% and 17% for cardiac dysfunction group and normal function group, respectively (p=0.637). In a multivariate Cox regression analysis, cardiac dysfunction was not associated with an increased risk of reintubation within 72 hours following extubation (hazard ratio, 1.56; p=0.292). Conclusion: Cardiac dysfunction was not associated with increased reintubation rate within 72 hours when HFNC is immediately applied after planned extubation.

  • Purpose: This study was a retrospective cohort study to evaluate the effect of evidence-based guidelines for catheter dysfunction among hemodialysis patients, Success rate and bleeding complications in catheterization were examined. Methods: We performed a retrospective cohort study, including 94 patients with catheter dysfunction who were receiving hemodialysis at a university hospital; 55 in the control group and 39 in the protocol group. This protocol was composed of the catheter dysfunction assessment, conservative management of catheter dysfunction, drug management of catheter dysfunction, catheter function test and maintenance management. Data were analyzed with a Chi-square test and t-test using SPSS/WIN 23.0 program. Results: The patency rate of the protocol group was significantly higher than that of the control group. The rate of bleeding complications was not statistically significant for either the control group or the protocol group before or after application. Conclusion: The application of the guidelines effectively increased the patency rate of the catheter without bleeding complications. It is hoped that this guideline can be disseminated to nurses nationwide to improve the efficiency of catheter function for hemodialysis patients.
