OBJECTIVES: Clinical utility of the Short Form of the Samsung Dementia Questionnaire (S-SDQ) as a screening instrument for Mild Cognitive Impairment (MCI). METHODS: Three groups (n=27, Subjective Memory Impairment (SMI); n=41 MCI; n=79, Early Alzheimer's Disease(AD)) recruited from memory clinic were administered a battery of neuropsychological tests including S-SDQ and Korean version-Mini Mental State Examination (K-MMSE). RESULTS: S-SDQ, unlike the K-MMSE, had no association with the age and education of the subjects. Scores of S-SDQ was found to correlate (r=-.496) with scores of K-MMSE. Result of Receiver Operating Characteristic (ROC) analysis revealed that S-SDQ discriminated between the SMI and the MCI groups. CONCLUSION: S-SDQ may be a solution to the problem of contamination by education and age which affect traditional cognitive screening instruments like K-MMSE, and it may be a useful tool for screening MCI.

Cecal volvulus is uncommon in pediatric patients and there are few reports of cecal volvulus with cerebral palsy. Here, we report the case of a 19-year-old male patient who presented with abdominal distension, a history of cerebral palsy, refractory epilepsy due to lissencephaly, and chronic constipation. An abdominal x-ray and computed tomography without contrast enhancement showed fixed dilated bowel intensity in the right lower abdomen. Despite decompression with gastric and rectal tube insertion, symptoms did not improve. The patient underwent an exploratory laparotomy that revealed cecal volvulus. Cecal volvulus usually occurs following intestinal malrotation or previous surgery. In this patient, however, intestinal distension accompanying mental disability and chronic constipation resulted in the development of cecal volvulus. We suggest that cecal and proximal large bowel volvulus should be considered in patients presenting with progressive abdominal distension combined with a history of neuro-developmental delay and constipation.

This report describes a case of a 40-year-old female patient with concurrent invasive ductal carcinoma of the breast and malignant follicular lymphoma, initially suspected to be metastatic breast cancer. During the initial evaluation of invasive ductal carcinoma of right breast, multiple lymphadenopathies were noted throughout the body on ultrasonography and positron emission tomography/computed tomography images. Clinically, metastatic breast cancer was suggested, and the patient was administered chemotherapy, including hormonal therapy. The breast cancer improved slightly, but the lymphadenopathies progressed and excisional biopsy of a cervical lymph node revealed malignant follicular lymphoma.

BACKGROUND/AIMS: Encapsulating peritoneal sclerosis (EPS) is an often-fatal complication of long-term peritoneal dialysis (PD). We here report the clinical features of EPS in Korean PD patients from a single university center. METHODS: The data were collected retrospectively from 606 PD patients at Kyungpook National University Hospital, between August 2001 and August 2011. The diagnosis of EPS was based on clinical signs and symptoms, and confirmed by radiological findings. RESULTS: Eight patients (1.3%, four males) were diagnosed with EPS. The mean age of the patients was 48.5 years (range, 33 to 65). The mean duration of PD was 111.8 months (range, 23 to 186). All patients except for one had three or more episodes of peritonitis. Seven patients were diagnosed with EPS after stopping PD, and only one stayed on PD after initial diagnosis and treatment. Total parenteral nutrition and corticosteroids, in addition to tamoxifen therapy, were used to treat most of the patients, and one patient underwent surgery (adhesiolysis). The overall mortality rate was 50%. CONCLUSIONS: EPS is a serious, life-threatening complication in patients on long-term PD. To reduce the incidence and mortality rate of EPS, careful monitoring and early diagnosis is needed.

Background: Preeclampsia (PE) is known to arise from insufficient trophoblast invasion as uterine spiral arteries lack remodeling. A significant reduction in placental perfusion induces an ischemic placental microenvironment due to reduced oxygen delivery to the placenta and fetus, leading to oxidative stress. Mitochondria are involved in the regulation of cellular metabolism and the production of reactive oxygen species (ROS). NME/NM23 nuceloside diphosphate kinase 4 (NME4) gene is known to have the ability to supply nucleotide triphosphate and deoxynucleotide triphosphate for replication and transcription of mitochondria. Our study aimed to investigate changes in NME4 expression in PE using trophoblast stem-like cells (TSLCs) from induced pluripotent stem cells (iPSCs) as a model of early pregnancy and peripheral blood mononuclear cells (PBMNCs) as a model of late preterm pregnancy. Methods: Transcriptome analysis using TSLCs was performed to identify the candidate gene associated with the possible pathophysiology of PE. Then, the expression of NME4 associated with mitochondrial function, p53 associated with cell death, and thioredoxin (TRX) linked to ROS were investigated through qRT-PCR, western blotting and deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate (dUTP) nick end labelling (TUNEL) assay. Results: In patients with PE, NME4 was significantly downregulated in TSLCs but upregulated in PBMNCs. p53 was shown to be upregulated in TSLCs and PBMNCs of PE. In addition, western blot analysis confirmed that TRX expression had the tendency to increase in TSLCs of PE. Similarly, TUNEL analysis confirmed that the dead cells were higher in PE than in normal pregnancy. Conclusion Our study showed that the expression of the NME4 differed between models of early and late preterm pregnancy of PE, and suggests that this expression pattern may be a potential biomarker for early diagnosis of PE.

OBJECTIVE: To assess prosthetic use by upper extremity amputees, and their difficulties with prostheses in activities of daily living and occupations. METHOD: This study is based on a survey of 307 subjects, who were using prostheses manufactured in the Center of Prosthetics and Orthotics. The survey questionnaire included items about general demographic characteristics, side and level of amputation, type of prosthesis and its use, and difficulties in the activities of daily living, employment and driving. RESULTS: The most common type of prosthesis was the cosmetic hand type (80.2%). There were no statistically significant correlations between satisfaction with prosthesis and the amputation level or type of prosthesis. The most common difficulties in daily living activities experienced by amputees were lacing shoes, removing bottle-tops with a bottle opener, and using scissors. Only 7.3% of amputees received rehabilitation services. Less than half of the amputees (44.7%) used their prostheses for eight or more hours a day, and 76.9% used their prostheses for regular or irregular cosmetic purposes. After amputation, most of the respondents (69.0%) became unemployed or changed workplaces. CONCLUSION: In our study, respondents preferred cosmetic usage to functional usage. Only 30.0% of respondents reported satisfaction with their prostheses. Many of the amputees had difficulties in complex tasks and either changed jobs or became unemployed. Clerical workers were the occupation group, which was most likely to return to work. The development of a more functional prosthetic hand and additional rehabilitation services are required.

OBJECTIVE: We compared the cell responsiveness of activated lymphocytes to rapamycin, which blocks the G1/S transition, between patients with Alzheimer's disease (AD) and normal controls to assess the early phase control defect in cell cycle. METHODS: Blood samples of 26 patients with AD and 28 normal controls were collected to separate peripheral lymphocytes. We measured the proportion of each cell cycle phase in activated lymphocytes using flow cytometry and evaluated the responsiveness of these lymphocytes to rapamycin. RESULTS: The patients with AD were older than the normal controls (AD 74.03+/-7.90 yr vs. control 68.28+/-6.21 yr, p=0.004). The proportion of G1 phase cells in the AD group was significantly lower than that in the control group (70.29+/-6.32% vs. 76.03+/-9.05%, p=0.01), and the proportion of S phase cells in the AD group was higher than that in control group (12.45+/-6.09% vs. 6.03+/-5.11%, p=0.001). Activated lymphocytes in patients with AD were not arrested in the G1 phase and they progressed to the late phase of the cell cycle despite rapamycin treatment, in contrast to those of normal subjects. CONCLUSION: The patients with AD probably have a control defect of early phase cell cycle in peripheral lymphocytes that may be associated with the underlying pathology of neuronal death.

BACKGROUND: This study was conducted to develop a pre-discharge group education program for liver transplant patients, and to contribute to improving the knowledge and performance of self-management after discharge. METHODS: This investigation was a methodological study consisting of analysis, design, development, operation, and evaluation stages. RESULTS: The constituent items of the pre-discharge group education program for liver transplant patients include medication management, infection management, emergency management, outpatient management, complication management, nutrition management, exercise management, wound and drainage management, disability registration, and sex life. The pre-discharge group education program for liver transplant patients was conducted once a week, 30 minutes for the coordinator, 40 minutes for the clinical nurse specialist (including 10 minutes for wound and drainage management), 30 minutes for pharmacists, 20 minutes for the nutritionist, and 20 minutes for social workers. Additionally, the contents of the lecture announced by PowerPoint were made the same as the booklet. The overall knowledge level before and 3 months after the pre-discharge group education program for liver transplantation patients increased significantly from 17.32±1.53 to 19.74±0.89. At the 3-month time point, the overall compliance was 77.39±3.04 out of 80. Overall satisfaction was 9.32±0.93 on a scale of 10. Finally, the need for medication was the highest at 3 months. CONCLUSIONS: It is expected that this program can be utilized in the clinical field as an effective nursing education intervention.

OBJECTIVE: This study examined the efficacy and safety of memantine-an uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist-in the treatment of moderate-to-severe dementia. METHODS: Forty-four patients with moderate-to-severe dementia received 20 mg of memantine daily for 24 weeks. The primary efficacy variable was measured by the Korean version of Severe Impairment Battery(K-SIB), and the secondary efficacy variables were measured using the Seoul-Activites of Daily Living(S-ADL) and Neuropsychiatric Inventory-Questionnaire(NPI-Q). Neuropsychological assessments were administrated at baseline, 12 weeks, and 24 weeks. Safety parameters were monitored. RESULTS: Of 44 patients recruited, 30 completed the study and 14 dropped out. Memantine-treated patients showed a therapeutic benefit in all efficacy variables ; the K-SIB, S-ADL, and NPI-Q total scores were not significantly different from baseline either at the endpoint(in the analysis of intention-to-treat, with the last observation carried forward, ITT-LOCF) or at week 24(in the analysis of observed cases, OC). The response rates, when "response" was defined as improved or unchanged in the K-SIB or the S-ADL scores, were 43.3 and 50%, respectively(in the analysis of OC). The responders showed significant improvement in the cognitive subdomain of memory function, praxis, visuospatial ability, and orienting to name. Memantine was shown to be tolerable and safe. CONCLUSIONS: Memantine treatment reduced or delayed clinical deterioration in cognition, function, and behavior in patients with moderate-to-severe dementia.

PURPOSE: This study aimed to examine the perception of food allergy among parents and school health instructors in Korea. METHODS: A nationwide epidemiological survey in Korea was conducted in September 2015. From 17 cities and provinces, a total of 1,000 elementary, middle and high schools were selected by stratified random sampling. Parents and school health instructors were surveyed using a questionnaire on the perception of food allergy. RESULTS: The prevalence of food-induced anaphylaxis was 22.3%. Of 252 children with anaphylaxis, 47.6% were prescribed epinephrine auto-injector (EAI). Forty-three parents (37.7%) were educated about the use of EAI. Parents carrying their own EAI at all times or keeping them at schools were 5.6% and 3.8%, respectively. For the food allergen-labeling system, 42.1% of parents read food labels, and 32.1% were satisfied with the system. Only 35.2% of school health instructors received education on food allergy and anaphylaxis, and 42.5% of them knew how to use EAI. There were 70 children (9.4%) with anaphylaxis in school, and 75.9% of schools had the emergency management system. CONCLUSION: The awareness of Korean parents and school health instructors on food allergy is still low, and many parents are dissatisfied with the food allergen labeling system. Many school health instructors have difficulty in using EAI in case of anaphylaxis and are insufficiently educated about food allergy. Therefore, it is necessary to establish more systematic food allergy management plans by providing high-quality education to parents and school health instructors and by utilizing legal systems.
