Background: This study aimed to investigate the recent prevalence, management, and comorbidities of diabetes among Korean adults aged ≥30 years by analyzing nationally representative data. Methods: This study used data from the Korea National Health and Nutrition Examination Survey from 2016 to 2018, and the percentage and total number of people ≥30 years of age with diabetes and impaired fasting glucose (IFG) were estimated. Results: In 2018, 13.8% of Korean adults aged ≥30 years had diabetes, and adults aged ≥65 years showed a prevalence rate of 28%. The prevalence of IFG was 26.9% in adults aged ≥30 years. From 2016 to 2018, 35% of the subjects with diabetes were not aware of their condition. Regarding comorbidities, 53.2% and 61.3% were obese and hypertensive, respectively, and 72% had hypercholesterolemia as defined by low-density lipoprotein cholesterol (LDL-C) ≥100 mg/dL in people with diabetes. Of the subjects with diabetes, 43.7% had both hypertension and hypercholesterolemia. With regard to glycemic control, only 28.3% reached the target level of <6.5%. Moreover, only 11.5% of subjects with diabetes met all three targets of glycosylated hemoglobin, blood pressure, and LDL-C. The percentage of energy intake from carbohydrates was higher in diabetes patients than in those without diabetes, while that from protein and fat was lower in subjects with diabetes. Conclusion The high prevalence and low control rate of diabetes and its comorbidities in Korean adults were confirmed. More stringent efforts are needed to improve the comprehensive management of diabetes to reduce diabetes-related morbidity and mortality.

The Committee of Clinical Practice Guidelines of the Korean Diabetes Association (KDA) updated the previous clinical practice guidelines for Korean adults with diabetes and prediabetes and published the seventh edition in May 2021. We performed a comprehensive systematic review of recent clinical trials and evidence that could be applicable in real-world practice and suitable for the Korean population. The guideline is provided for all healthcare providers including physicians, diabetes experts, and certified diabetes educators across the country who manage patients with diabetes or the individuals at the risk of developing diabetes mellitus. The recommendations for screening diabetes and glucose-lowering agents have been revised and updated. New sections for continuous glucose monitoring, insulin pump use, and non-alcoholic fatty liver disease in patients with diabetes mellitus have been added. The KDA recommends active vaccination for coronavirus disease 2019 in patients with diabetes during the pandemic. An abridgement that contains practical information for patient education and systematic management in the clinic was published separately.

BACKGROUND: Although several hospital-based stroke studies were published, there has not been any reliable data representing the clinical characteristics of stroke in Korea. We analyzed the clinical characteristics of patients with ischemic stroke registered in the Korean Stroke Registry (KSR), which is the largest prospective hospital-based nation-wide stroke registry in Korea. METHODS: The KSR provided standardized protocols for collecting data, which includes the data of demographics, subtypes of stroke, risk factors, and neurological outcome at discharge. The brain imaging studies, including CT or MRI, were performed in all cases. RESULTS: KSR registered 10,811 patients of acute ischemic stroke between Nov. 2002 and Jun. 2004. The large-artery atherosclerosis was the most common subtype (37.3%), followed by small vessel occlusion (30.8%). Hypertension (65.4%) was the most common risk factor, followed by smoking (34.5%) and diabetes (28.3%). Although most of the hypertensive and diabetic patients had been diagnosed before the stroke, less than 45.4% and 32.5% of them were under regular control. The steno-occlusive lesion of extracranial carotid artery was only 29.3% and the ratio of intra- to extracranial artery disease was more than 2 in KSR. Only 20.5% of patients were admitted within 3 hours after stroke onset and 2.1% were treated with intravenous thrombolysis. In-hospital case-fatality was 5.2%, which is relatively comparable to those of previous studies. CONCLUSIONS: The KSR provided informative data in understanding the clinical characteristics of ischemic stroke in Korea. Further analysis of KSR will facilitate clinical trials and development of guidelines for the management of stroke patients.

Chloroma, a tumor consisted of primitive myeloid cells and located in extramedullary tissues, usually develops during or preceding the course of systemic leukemia, particularly acute myelogenous leukemia (FAB M2) with translocation between chromosomes 8 and 21. Leukemic retinopathy which observed rarely in children than adults, generally related to thrombocytopenia and anemia in leukemic patients. Bronchiolitis obliterans organizing pneumonia (BOOP) is unusual clinicopathologic syndrome in association with a variety of causes or conditions, and histologically defined by the presentation of granulation tissue plugs consisting of fibroblasts and collagen within the lumen of the distal air space. We experienced a 12-year old girl who presented with weakness and ocular pain. She was diagnosed with acute myeloid leukemia with chloroma and retinopathy, and treated with chemotherapy (daunomycin, ara-C, thioguanine, etoposide. mitoxantrone, cyclosporin). Five weeks after the chemotherapy, she developed coughing and persistent fever, and diagnosed with BOOP, which resolved completely after prednisolone therapy.

OBJECTIVES: We carried out tests for neurobehavior by using WHO-NCTB (neurobehavioral core test battery) and Perdue pegboard score test to identify differences between lacunar infarction cases and controls. METHODS: Among the subjects who underwent MRI between February 2001 and March 2002 in a university hospital located in Seoul and who were diagnosed only as lacunar infarction without any intracranial disease, 46 patients were selected as cases (male: 21, female: 25). Controls were selected who had no cerebrovascular disease on MRI by matching age (5 years), gender, and education (2 years) in a ratio of 1: 1. Among WHO-NCTB, the following 5 tests and Perdue pegboard score test were used to categorize the study subjects: digit and symbol matching, simple reaction time, Benton visual retention, digit span, and Pursuit aiming test. RESULTS: Among the above 6 tests of neurobehavior, lacunar infarction cases showed lower score than controls except for the simple reaction time test. As the controlling variables of multivariate analysis in the stepwise regression analysis, the followings were selected due to their significant association: age, education, BMI, gender, drinking, exercise, and systolic blood pressure. From multivariate regression analysis, there was significant difference (p< 0.05) between lacunar infarction cases and controls in digit and symbol matching, Benton visual retention, digit span, pursuit aiming, and Perdue pegboard score test, but not in the score of simple reaction time test. CONCLUSIONS: We suggest that the above 5 tests for neurobehavior, with the exception of the simple reaction time test, might be used as the basis for recommendation of further treatment and other neurological tests by the earlier detection for neurological abnormality in lacunar infarction.

PURPOSE: Inter-arm blood pressure differences of more than 10 mmHg are measured not only in patients who have vascular diseases, such as aortic dissections, and aortic aneurysms, but also in heathy patients. We investigated the degree of and the factors for normal inter-arm blood pressure variations in our country. METHODS: We prospectively studied the cases of 351 patients who visited the Emergency Department of Korea University Hospital between May 1 and July 31, 2001. we collected clinical and demographic data, including age, sex, right/left handedness, and bilateral blood pressure. After we divided the cases into a Normal blood pressure group and a High blood pressure group, we compared the inter-arm blood pressure difference and influencing factors between the two group. RESULTS: The variation in the inter-arm blood pressure was unrelated to age, sex, right/left handedness, and right/left arm in both groups. In the Normal blood pressure group (n=180), the systolic inter-arm blood pressure difference was 3.9+/-0.4 mmHg, and the diastolic inter-arm blood pressure difference was 3.6+/-0.4 mmHg. In the High blood pressure group (n=171), the systolic inter-arm blood pressure difference was 5.2+/-0.5 mmHg, and the diastolic interarm blood pressure difference was 4.8+/-0.5 mmHg. CONCLUSION: The variation in the inter-arm blood pressure was unrelated to age, sex, right/left handedness, and right/left arm. But inter-arm blood pressure difference was significant among subjects without exclusion criteria and was measured as about 5 mmHg in two groups.

Common complications of the intestinal tuberculosis are perforation, obstruction, fistulas, and malabsorption. Massive gastrointestinal bleeding is an extremely rare complication of intestinal tuberculosis. Moreover, this may be the first report in the world on transcatheter arterial embolization against the massive bleeding from intestinal tuberculosis patient. We experienced a case of lower gastrointestinal bleeding due to extensive intestinal tuberculosis as massive as vital sign was unstable. Colonoscopy and esophagogastroduodenoscopy did not reveal bleeding focus. Active jejunal bleeding was suspected by technetium99m labelled RBC scintigraphy. Emergency superior mesenteric artery angiography showed active bleeding focus from jejunal branch of artery and transcatheter arterial embolization was tried with microcoil. After embolization, he had no more hematochezia and vital sign became stabilized. On third hospital day, upper endoscopy was done using pediatric colonoscopy and there were multiple circular ulcers on the proximal jejunum but no evidence of mesenteric ischemia. Small bowel tuberculosis should be suspected as a cause of lower gastrointestinal bleeding in case of negative colonoscopy and upper endoscopy. We suggest that the transcatheter embolization could be taken into consideration as a first-line method of treatment for massive bleeding from intestinal tuberculosis before surgical resection.

Polymyositis is an inflammatory, autoimmune disease of the skeletal muscle characterized by symmetrical, proximal muscle weakness, elevated muscle enzymes, and characteristic features on electromyogram and muscle biopsy. The kidneys are generally spared and myoglobinuric renal failure is very rare in polymyositis. There have been infrequent reports of polymyositis developing myoglobinuric renal failure secondary to rhabdomyolysis. The flare-up may occur in polymyositis, usually manifest within several weeks to months of achieving a remission. But, rhabdomyolysis and myoglobinuric renal failure was a very rare feature of the relapse of polymyositis. We present a case report of patient with polymyositis who initially presented and relapsed as rhabodomyolysis that lead to myoglobinuric, oliguric renal failure and required transient dialytic support.

Primary carcinoid tumor of duodenum are rare, Usually, small duodenal carcinoid tumors are often discovered endoscopically. Most of these tumors are asymptomatic, but in rare cases, jaundice, hemorrhage, duodenal obstruction, or carcinoid syndrome were apparent. Uaually, the recommended treatment is surgical or endoscopic excision of the tumor. We experienced a case of carcinoid tumor of duodenu in 53 year-old women. A 53-year-old female patient was admitted to our hospital because of epigastric discomfort and indigestion. On the gastrofiberscopic examination, 0.9 cm sized polypoid mass with central umblication was noted on the duodenall bulb. The biopsy specimen showed carcinoid cells. She was treated with endoscopic polypectomy.
