Diencephalic syndrome is a rare cause of failure to thrive in infancy and early childhood. The syndrome is characterized by profound emaciation with normal appetite, loss of cutaneous adipose tissue, hyperactivity, euphoria, and nystagmus. It commonly occurs in association with chiasmatic and hypothalamic gliomas. It has also been described in association with other histologic types. There is the marked increase of serum growth hormone, which may exhibit an inappropriate, even paradoxical response in stimulation test. A male infant of 12 months of age, showed markedly elevated growth hormone but he had failure to thrive findings. Evenly enhanced round mass was seen at suprasella area in brain CT. Its histological findings was "Desmoplastic infantile ganglioglioma", very rare histologic type. Here we report a case of diencephalic syndrome presented by failure to thrive in association with hypothalamic tumors.

OBJECTIVE: This study was to change of pulp blood flow among maxillary and mandibular anterior tooth with mild crowding and adjacent teeth using Ultrasound Doppler graphy. METHODS: The change of pulp blood flow was measured three times using Ultrasound Doppler graphy; before the attachment of brackets, after 3 week, and after 6 week. The sample consists of 15 year old eighteen patients. RESULTS: Before the attachment of brackets, after 3 weeks, and after 6 weeks, there were no significant differences in the change of pulp blood flow in each part (maxilla and mandible) and each tooth according to period. In addition, to compare internal dangerousness of loss of the pulp vitality, when pulp blood flow is compared in each tooth before orthodontic treatment, there were no statistically significant differences in maxillary lateral incisor and mandibular canine but it showed low values in all measurement items (p > 0.05). CONCLUSIONS: Results of this study can be not only methodological preliminary data in further study such as tooth movement type of Ultrasound Doppler graphy and particular study considered the patient age, but also reference materials for the loss of pulp vitality in orthodontic treatment.

PURPOSE: We investigated the operative outcome after bypass surgery in patients selected using viability criteria on F-18 FDG PET. MATERALS AND METHODS: Rest-24hr delay redistribution imaging of Tl-201 SPECT and F-18 FDG PET were performed in 11 patients. Seven of these 11 patients (6 men, 1 woman) were evaluated to have viable myocardium by F-18 FDG PET. Changes in symptoms and left ventricular ejection fraction (LVEF) after operation were evaluated. RESULTS: In seven of 11 patients, a significant amount of viable myocardium was found on F-18 FDG PET and Tl-201 SPECT. Severity of both chest pain and dyspnea improved markedly in all patients. Mean LVEF improved from 22% to 32%. CONCLUSION: F-18 FDG PET could be used to select the patients who will benefit from coronary artery bypass surgery.

BACKGROUND: The selective media for culture of Helicobacter pylori(H. pylori) are Egg yolk emulsion medium, modified Thayer-Martin medium and Skirrow's medium. The non-selective media for culture of H. pylori are brucella agar, trypticase soy agar, and brain heart infusion agar. The selective media are more expensive and difficult to prepare than non-selective media, whereas non-selective media are difficult to isolate H. pylori due to contamination of upper respiratory tract bacteria. The objects of this study are to reduce upper respiratory contaminants by use of HCl-KCl buffer (H-K buffer) for primary isolation, and to compare with culture, CLO test, histologic examination and H. pylori IgG antibodies. METHODS: Seventy one patients underwent upper gastrointestinal endoscopy with biopsy. For 32 patients, two biopsies were taken from antrum: One for direct inoculation into blood agar plate, the other for pretreatment of H-K buffer. For fifty six patients, we performed culture, CLO test, histology, and H. pylori IgG. RESULTS: 1) Among the 32 patients, H. pylori were isolated in 25 patients (23 patients for direct inoculation and 25 patients for H-K pretreatment). Twelve cases among H-K buffer treatment group did not show contamination, whereas only two among direct inoculation group showed no contamination. The average number of contaminating colony forming unit (CFU) of direct inoculation and H-K buffer treatment were 77 and 9, respectively. 2) The positive rates of culture and CLO test, histology, and H. pylori IgG for H. pylori infection were 71.4%, 67.9%, 75.0%, and 57.1%, respective

BACKGROUND: In cardiac arrest, the survival rate increases with the provision of bystander cardiopulmonary resuscitation (CPR), of which the initial response and treatment are critical. Telephone CPR is among the effective methods that might increase the provision of bystander CPR. This study aimed to describe and examine the improvement of neurological outcomes in individuals with out-of-hospital acute cardiac arrest by implementing the nationwide, standardized telephone CPR program. METHODS: Data from the emergency medical service-based cardiac arrest registry that were collected between 2009 and 2014 were used. The effectiveness of the intervention in the interrupted time-series study was determined via a segmented regression analysis, which showed the risk ratio and risk difference in good neurological outcomes before and after the intervention. RESULTS: Of 164,221 patients, 148,403 were analyzed. However, patients with unknown sex and limited data on treatment outcomes were excluded. Approximately 64.3% patients were men, with an average age of 63.7 years. The number of bystander CPR increased by 3.3 times (95% confidence interval [CI], 3.1–3.5) after the intervention, whereas the rate of good neurological outcomes increased by 2.6 times (95% CI, 2.3–2.9 [1.6%]; 1.4–1.7). The excess number was identified based on the differences between the observed and predicted trends. In total, 2,127 cases of out-of-hospital cardiac arrest (OHCA) after the intervention period received additional bystander CPR, and 339 cases of OHCA had good neurological outcomes. CONCLUSION: The nationwide implementation of the standardized telephone CPR program increased the number of bystander CPR and improved good neurological outcomes.

OBJECTIVE: This study investigated the proposed association between restless legs syndrome (RLS) and the prevalence of hypertension. METHODS: A meta-analysis was conducted based on searches of the PUBMED, EMBASE, Cochrane Library, and Korean electronic databases. Cohort and cross-sectional studies reporting the incidence of hypertension in individuals with RLS were included. Dichotomous data were pooled to obtain an odds ratio (OR) and 95% confidence interval (CI) for the prevalence of hypertension in individuals with RLS. The main outcome measure of the study was prevalence of hypertension in patients with RLS compared with a control group. RESULTS: One cohort study and eight cross-sectional studies were included in the meta-analysis. Individuals with RLS had an increased prevalence of hypertension (all studies: OR=1.13, 95% CI=1.04–1.23; cross-sectional studies: OR=1.12, 95% CI=1.01–1.24). However, in subgroup analyses controlling for cardiovascular risk factors, such as diabetes mellitus and dyslipidemia, the differences in the prevalence of hypertension between RLS and control patients were no longer significant. CONCLUSION: Patients with RLS may have a higher prevalence of hypertension, according to a pooled analysis, but the results remain to be confirmed in well-designed prospective studies.

Hereditary angioedema (HAE) is a rare autosomal dominant disorder caused by genetic deficiency or decreased function of C1-esterase inhibitor. It is characterized by swelling of subcutaneous and submucosal tissues of the extremities, gastrointestinal tract, and upper airways which can be life-threatening. Thus, early recognition and treatment of the disease are important. Short- and longterm prophylaxes are used to decrease the severity and frequency of attacks. Icatibant is a selective bradykinin B2-receptor antagonist, earlier treatment of acute attacks and hospital admission. The authors present a case of 47-year-old woman who was diagnosed with type II HAE, danazol as a long term. Her symptoms improved dramatically after drug treatment. The unpredictability and recurrence of HAE attacks could have a negative impact on social life and quality of life. This case shows that timely and proper treatment could improve quality of life and reduce morbidity and mortality. (

Background:
In this study, with the aim of improving the quality of transitional care service for discharged patients, the Health Care Quality and Outcomes Indicators of the Organization for Economic Co-operation and Development and National Health Service Outcomes Framework of the UK were applied to derive service items for provision and develop evaluation indicators under categories of effectiveness, safety, and patient-centeredness.Method: A scoping review was conducted to derive core concepts and evidence materials/data for transitional care service. For the derived items of transitional care service and evaluation indicators, a three-round Delphi study was conducted with experts in the fields of healthcare/ medicineursing/social welfare.
Results:
First, as a result of the scoping review, components of transitional care service (assessment of need by period of transitional care service, multi-professional team, connection to community resources, etc.) and themes for outcome indicators (effectiveness, patient safety, patient-centeredness) were derived. Second, by classifying the items for assessment according to the hospitalization and transition period and conducting a Delphi study to derive service items for transitional care service, during the hospitalization period, presence/absence of a caregiver and need for a caregiver, activities of daily living, and necessity for home-based care services were identified as items of high priority. Regarding patient safety, risk of falls and fractures during hospitalization, and necessity for medication reconciliation were identified as the items of high importance. For the transition period, provision of education regarding adequate responses and handling of emergencies, provision of information and guidance on application of services for basic livelihood security program beneficiaries, and education for patient skills in self-management of health were derived as items of high priority. Third, for the derivation of outcome indicators for transitional care service, in the “effectiveness” category, the experts rated a reduction in the 30-day readmission rate as an item of high importance along with a decrease in emergency department visits, reduction in preventable admissions as indicators of high relevance. In terms of “patient safety,” a decrease in drug adverse reactions, and reduction in the incidence of falls and pressure ulcers were identified as indicators of high priority. Finally, for the category of “patient-centeredness,” patient experience assessment, level of service satisfaction reported by patients and their caregivers, and reducing burden on caregivers were identified as indicators of high priority.
Conclusion
This study suggest practical implications for the service with high relevance and necessity for transitional period. It also presented outcome indicators of transitional care service to contribute toward an improvement in the quality of care.

Purpose:
The microenvironment of pancreatic ductal adenocarcinoma (PDAC) with extensive desmoplastic stroma contributes to aggressive cancer behavior. Angiotensin system inhibitors (ASIs) reduce stromal fibrosis and are a promising therapeutic strategy. The purpose of this study was to examine how ASIs affected the oncological results of patients who had their PDAC removed.
Materials and Methods:
A retrospective assessment was conducted on the clinicopathological and survival data of patients who received curative resection for PDAC at Severance Hospital between January 2012 and December 2019.
Results:
A total of 410 participants (228 male and 182 female), with a median follow-up period of 12.8 months, were included in this study. Patients were divided into three groups, based on ASI use and history of hypertension: group 1, normotensive and never used ASI (n=210, 51.2%); group 2, ASI non-users with hypertension (n=50, 12.2%); and group 3, ASI users with hypertension (n=150, 36.6%). The three groups did not differ significantly in terms of age, sex, kind of operation, T and N stages, or adjuvant and neoadjuvant therapy. Moreover, there was no discernible difference in disease-free survival between those who used ASI and those who did not (p=0.636). The 5-year overall survival (OS) rates in groups 1, 2, and 3 were 52.6%, 32.3%, and 38.0%, respectively. However, the OS rate of ASI users was remarkably higher than that of non-users (p=0.016).
Conclusion
In patients with resected PDAC, ASI is linked to longer survival rates. Furthermore, for individuals with hypertension, ASI in conjunction with conventional chemotherapy may be an easy and successful treatment option.
