Background/Aims: This study evaluated the long-term cardiovascular complications among Korean patients with hypertension and compared them with that of controls without hypertension. Methods: The Korean Hypertension Cohort (KHC) enrolled 11,043 patients with hypertension and followed them for more than 10 years. Age- and sex-matched controls without hypertension were enrolled at a 1:10 ratio. We compared the incidence of cardiovascular events and death among patients and controls without hypertension. Results: The mean age was 59 years, and 34.8% and 16.5% of the patients belonged to the high and moderate cardiovascular risk groups, respectively. During the 10-year follow-up, 1,591 cardiovascular events (14.4%) with 588 deaths (5.3%) occurred among patients with hypertension and 7,635 cardiovascular events (6.9%) with 4,826 deaths (4.4%) occurred among controls. Even the low-risk population with hypertension showed a higher cardiovascular event rate than the population without hypertension. Although blood pressure measurements in the clinic showed remarkable inaccuracy compared with those measured in the national health examinations, systolic blood pressure (SBP) ≥ 150 mmHg was significantly associated with a higher risk of cardiovascular events. Conclusions This long-term follow-up study confirmed the cardiovascular event rates among Korean hypertensive patients were substantial, reaching 15% in 10 years. SBP levels ≥ 150 mmHg were highly associated with occurrence of cardiovascular event rates.

Background: This study presents a novel technical tip for intraoperative tumor localization and determination of the proximal resection line using a titanium ring strip for totally laparoscopic distal gastrectomy in patients with middle-third gastric cancer and describes the short-term results of its application. Methods: In total, 42 patients with middle-third gastric cancer who underwent intraoperative tumor localization using a titanium ring strip and determination of the proximal resection line through intraoperative radiography between January 2020 and December 2021 were enrolled in this study. We retrospectively analyzed patients’ prospectively collected clinical, pathological, and surgical data. Results: Twenty-six men and 16 women with a mean age of 58.3±12.5 years were enrolled. The mean operation time and estimated blood loss were 212.6±43.0 minutes and 122.4±77.6 mL, respectively. The lengths of the proximal and distal resection margin were 2.0±0.4 cm (range, 0.8–3.7 cm) and 10.5±4.1 cm (range, 0.4–20.4 cm), respectively. Roux-en-Y anastomosis was performed in 30 patients, while Billroth II with Braun anastomosis was performed in 12 patients. There were no procedure-related complications, and the mean postoperative hospital stay was 7.2±1.9 days. For all patients, the negative proximal resection margin was confirmed by postoperative pathological examinations. Conclusions Intraoperative tumor localization and determination of the proximal resection line using a titanium ring strip is a useful alternative method that can be easily and safely performed. This method is especially useful for patients with middle-third gastric cancer requiring an appropriate proximal resection margin.

Background: There has been no comparison of the determinants of admission route between acute ischemic stroke (AIS) and acute myocardial infarction (AMI). We examined whether factors associated with direct versus transferred-in admission to regional cardiocerebrovascular centers (RCVCs) differed between AIS and AMI. Methods: Using a nationwide RCVC registry, we identified consecutive patients presenting with AMI and AIS between July 2016 and December 2018. We explored factors associated with direct admission to RCVCs in patients with AIS and AMI and examined whether those associations differed between AIS and AMI, including interaction terms between each factor and disease type in multivariable models. To explore the influence of emergency medical service (EMS) paramedics on hospital selection, stratified analyses according to use of EMS were also performed. Results: Among the 17,897 and 8,927 AIS and AMI patients, 66.6% and 48.2% were directly admitted to RCVCs, respectively. Multivariable analysis showed that previous coronary heart disease, prehospital awareness, higher education level, and EMS use increased the odds of direct admission to RCVCs, but the odds ratio (OR) was different between AIS and AMI (for the first 3 factors, AMI > AIS; for EMS use, AMI < AIS). EMS use was the single most important factor for both AIS and AMI (OR, 4.72 vs. 3.90). Hypertension and hyperlipidemia increased, while living alone decreased the odds of direct admission only in AMI;additionally, age (65–74 years), previous stroke, and presentation during non-working hours increased the odds only in AIS. EMS use weakened the associations between direct admission and most factors in both AIS and AMI. Conclusions Various patient factors were differentially associated with direct admission to RCVCs between AIS and AMI. Public education for symptom awareness and use of EMS is essential in optimizing the transportation and hospitalization of patients with AMI and AIS.

Background/Aims: Hypertension (HT) has a significant impact on public health and medical expenses. However, HT is a chronic disease that requires the long-term follow-up of a large number of patients. Methods: The Korean Hypertension Cohort (KHC) study aimed to develop a model for calculating cardiovascular risk in HT patients by linking and utilizing the detailed clinical and longitudinal data from hospitals and the national health insurance claim database, respectively. This cohort had a planned sample size of over 11,000 HT patients and 100,000 non-HT controls. Eligible patients were hypertensive patients, who were presenting for the first time and were diagnosed with HT as a main disease from 2006 to 2011. Long-term survival data over a period of approximately 9 years were obtained from the national health insurance claim and national health examination data. Results: This cohort enrolled 11,083 patients with HT. The mean age was 58.87 ± 11.5 years, 50.5% were male, and 31.4% were never-treated HT. Of the enrolled patients, 32.9% and 37.7% belonged to the high and moderate cardiovascular risk groups, respectively. Initial blood pressures were 149.4 ± 18.5/88.5 ± 12.5 mmHg. During the 2 years hospital data follow-up period, blood pressures lowered to 130.8 ± 14.1/78.0 ± 9.7 mmHg with 1.9 ± 1.0 tablet doses of antihypertensive medication. Cardiovascular events occurred in 7.5% of the overall patients; 8.5%, 8.8%, and 4.7% in the high, moderate, and low risk patients, respectively. Conclusions The KHC study has provided important information on the long-term outcomes of HT patients according to the blood pressure, comorbid diseases, medication, and adherence, as well as health behaviors and health resource use.

BACKGROUND/AIMS: For the treatment of malignant biliary obstruction, endoscopic retrograde biliary drainage (ERBD) has been widely accepted as a standard procedure. However, post-ERBD complications can affect the lives of patients. The purpose of this study was to identify the predictive factors for these complications, including the patient’s status, cancer status, and stent type.METHODS: This was a retrospective analysis conducted in a single tertiary hospital from January 2007 to July 2017. The following variables were evaluated: sex, age, body mass index, cancer type, history of pancreatitis, gallbladder stone, previous biliary stenting, precut papillotomy, stent type, contrast injection into the pancreatic duct or gallbladder, cystic duct invasion by the tumor, and occlusion of the cystic duct orifice by a metal stent.RESULTS: Multivariate analysis showed that contrast injection into the pancreatic duct was a risk factor for pancreatitis. Patients with a history of bile drainage showed a lower risk of pancreatitis. For cholecystitis, the analysis revealed contrast injection into the gallbladder and cystic duct invasion by the tumor as important predictive factors. Metal stents showed a greater risk of post-procedure pancreatitis than plastic stents, but did not affect the incidence of cholecystitis.CONCLUSIONS: Considering that contrast injection is the most important factor for both complications, a careful approach by the physician is essential in preventing the occurrence of any complications. Further, choosing the type of stent is an important factor for patients at a risk of post-procedure pancreatitis.

"Clinical Practice Guideline for Stroke Rehabilitation in Korea 2012" is a 2nd edition of clinical practice guideline (CPG) for stroke rehabilitation in Korea, which updates the 1st edition published in 2009. After 1st stroke rehabilitation CPG, many studies concerning stroke rehabilitation have been published and the necessity for update has been raised. The Korea Centers for Disease Control and Prevention supported the project "Development of Clinical Practice Guideline for Stroke Rehabilitation" in 2012. Thirty-two specialists in stroke rehabilitation from 18 universities and 3 rehabilitation hospitals and 10 consultants participated in this project. The scope of this CPG included both ischemic and hemorrhagic stroke from the acute to chronic stages. The purpose of this CPG is to provide guidelines for doctors and therapists to make a decision when they manage stroke patients and ultimately, to help stroke patients obtain maximal functional recovery and return to the society. "Clinical Practice Guideline for Stroke Rehabilitation in Korea 2012" consists of 'Chapter 1; Introduction of Stroke Rehabilitation', 'Chapter 2; Rehabilitation for Stroke Syndrome, 'Chapter 3; Rehabilitation for Return to the Society', and 'Chapter 4; Advanced Technique for Stroke Rehabilitation'. Both the adaptation and de novo development methods were used to develop this 2nd edition of CPG. The appraisal of foreign CPGs was performed using 'Korean appraisal of guidelines for research and evaluation II' (K-AGREE II); moreover, four CPGs from Scotland (2010), Austrailia (2010), USA (2010), Canada (2010) were chosen for adaptation. For de novo development, articles that were published following the latest foreign CPGs were searched from the database system, PubMed, Embase, and Cochrane library. Literatures were assessed in the aspect of subjects, study design, study results' consistency, language and application possibility in the Korean society. The chosen articles' level of evidence and grade of recommendation were decided by the criteria of Scotland (2010) and the formal consensus was derived by the nominal group technique. The levels of evidence range from 1++ to 4 and the grades of recommendation range from A to D. GPP (Good Practice Point) was recommended as best practice based on the clinical experience of the guideline developmental group. The draft of the developed CPG was reviewed by the experts group in the public hearings and then revised.

Gastric ulcer bleeding is commonly encountered in emergency situations for gastroenterologist. Usually depth of gastric ulcer does not exceed the muscle layer. We report a case of a 67-year-old male with massive gastric ulcer bleeding caused by direct connection to the splenic artery. Bleeding control was not effectively performed by endoscopy due to massive bleeding with unstable vital sign. Angiography for embolization was performed. Active extravasation of contrast agents at the splenic artery stenosis was noted on splenic arteriogram. Bleeding stopped after embolization with histoacryl and lipiodol was successfully performed. After 1 month, complete ulcer healing was confirmed by follow up endoscopy. There was no evidence of invasive disease on biopsy.

Monoballismus-monochorea is abnormal neurologic sign characterized by continuous, involuntary and irregular movement involving one extremity. Hyperglycemic ballism-chorea is predominantly observed in older type 2 diabetic patients and non-ketotic hyperglycemia, and is associated with contralateral striatal hyperintensities (i.e., putamen and caudate) on both brain CT and MRI. Movement disorders as the initial symptoms of diabetes mellitus are rare, especially in ketotic hyperglycemia. Here, we report one of these rare manifestations of transient monoballismus with during an episode of ketotic hyperglycemia without contralateral striatal abnormal findings on brain MRI in newly diagnosed diabetes mellitus.
