Arotinolol was administered orally to 31 patients to evaluate is antihypertensive action. After one week of antihypertensive medication, they were given Arotinolol 30mg daily for 4 week. Routine serum chemistries, electrolytes, urinalysis and electrocardiography were studied before and after Arotinolol. Blood pressure measured in sitting, supine and standing position was 175.3+/-5.4/115.7+/-4.0, 168.0+/-5.2/150.0+/-3.8, 154.4+/-8.5/103.4+/-3.2mmHg in control and 143.8+/-2.8/93.3+/-2.8, 144.6+/-5.4/88.1+/-4.3, 139.7+/-4.6/86.8+/-3.4mmHg in Arotinolol treatment group. The differences between both blood pressure were statistically significant(P<0.01). No laboratory test showed significant difference between both period. There were no significant side effects except 2 cases of transient headache and dizziness respectively, and one case of diarrhea. In summary, Arotinolol apears to reduce blood pressure effectively with minimal side effects.

PURPOSE: Irreparable massive rotator cuff tears pose a distinct clinical challenge for the orthopaedist and non-surgical treatment has had inconsistent results and proven unsuccessful for chronic symptoms, while surgery, including debridement and partial and complete repairs have had varying degrees of success. MATERIALS AND METHODS: For rotator cuff tears that are deemed irreparable, treatment options are limited. RESULTS AND CONCLUSION: The use of tendon transfers (latissimus dorsi for posterosuperior type cuff defects and pectoralis major for subscapularis defects) in younger patients to reconstruct rotator cuffs and re-establish function and restore shoulder kinematics can be useful in solving this difficult problem.

OBJECTIVES: This study was conducted in order to develop a computerized test to measure the level of mathematic achievement and related cognitive functions in children and adolescents in South Korea. METHODS: The computerized Comprehensive Learning Test-Mathematic (CLT-M) consists of the whole number computation test, enumeration of dot group test, number line estimation test, numeral comparing test (magnitude/distance), rapid automatized naming test, digit span test, and working memory test. To obtain the necessary data and to investigate the reliability and validity of this test, 399 children and adolescents from kindergarten to middle school were recruited. RESULTS: The internal consistency reliability of the CLT-M was high (Cronbach's alpha=0.76). Four factors explained 66.4% of the cumulative variances. In addition, the data for all of the CLT-M subtests were obtained. CONCLUSION: The computerized CLT-M can be used as a reliable and valid tool to evaluate the level of mathematical achievement and associated cognitive functions in Korean children and adolescents. This test can also be helpful to detect mathematical learning disabilities, including specific learning disorder with impairment in mathematics, in Korea.

Genetic factors are important host factors that play a role in the development of all diseases through their interaction with environmental factors. Most genetic disorders are the direct result of a mutation in a single gene. However, one of the most difficult challenges currently faced by researchers is the identification of ways in which genes contribute to diseases with complex inheritance patterns, such as cancer, diabetes, asthma, and mental illness. In all of these cases, no single gene determines whether a person will develop a disease. Several genes may contribute to an individual's susceptibility to a disease; genes may also affect how an individual reacts to environmental factors. In this study, we attempted to classify high-risk groups using up-to-date genetic knowledge. We also briefly discuss the role of scientific evidence in the identification (through genetic screening) and management of high-risk subgroups in the population.

Anemia is a common and significant complication of chronic kidney disease (CKD). However, its prevalence and current management status has not been studied thoroughly in Korea. We examined the prevalence of anemia, its association with clinical and laboratory factors, and utilization of iron agents and erythropoiesis stimulating agents using the baseline data from the large-scale CKD cohort in Korea. We defined anemia when hemoglobin level was lower than 13.0 g/dL in males and 12.0 g/dL in females, or received by erythropoiesis stimulating agents. Overall prevalence of anemia was 45.0% among 2,198 non-dialysis CKD patients from stage 1 to 5. Diabetic nephropathy (DN) as a cause, CKD stages, body mass index (BMI), smoking, leukocyte count, serum albumin, iron markers, calcium, and phosphorus concentration were identified as independent risk factors for anemia. Considering the current coverage of Korean National Health Insurance System, only 7.9% among applicable patients were managed by intravenous iron agents, and 42.7% were managed by erythropoiesis stimulating agents.

Brown-Séquard-plus syndrome is characterized by hemiparesis, contralateral spinothalamic sensory deficits with additional abnormal findings of other organs. We report a case of an 81-year-old man who had right hemiparesis, left sensory deficit and Horner syndrome on right eye. Diffusion-weighted MRI of the cervical spine and lower medulla confirm the diagnosis of anterior unilateral cervical spinal cord infarction. It is very rare that the unilateral long spinal cord infarction at the C1-C4 associated with Brown-Séquard-plus syndrome.

OBJECTIVES: The aim of this study was to develop the computerized Comprehensive Learning Test-Reading (CLT-R) to evaluate the cognitive processes and achievements related to their basic reading ability and identify dyslexia in children and adolescents in South Korea. We also obtained the normative data and evaluated the reliability and validity of the test. METHODS: We developed the CLT-R, including the word attack/nonword decoding, paragraph reading, sound blending, nonword repetition, rapid automatized naming, letter-sound matching, visual attention, orthography awareness, and digit span tests, for the purpose of diagnosing dyslexia. We investigated the reliability and validity of the tests and gathered the normative data from 399 subjects (male 48.9%), aged 5-14 years, from the last grade in kindergarten to middle school, dwelling in Seoul and Gyeonggi Province, South Korea. RESULTS: No statistical differences were observed between the means of the tests and retests of the CAT. The mean of the correlation coefficient of the test-retest scores was 0.85. According to the construct validity test calculated by principal constant analysis using the oblique rotation method, 4 factors explained 70.0% of the cumulative variances. In addition, the normative data were obtained for all of the CLT-R subtests. CONCLUSION: The computerized CLT-R can be used as a reliable and valid tool to evaluate the reading achievement and reading related cognitive process in Korean children and adolescents in schools, clinics, and research institutes.

Hypoglycemia sometimes manifests as focal neurologic deficits simulating cerebrovascular disease. Symptoms are usually resolved by glucose infusion, but persistent hemiplegia is rarely reported. A 68-year-old diabetic woman on oral hypoglycemic agent(OHA) was admitted with right hemiplegia and global aphasia. Blood glucose level was 29 mg/dl on admission. No evidence of cerebral infarct or underlying brain disease could be found on initial brain CT and follow up MRI. Focal stenosis or occlusion was also absent on MR angiography. Hemiplegia and aphasia were not improved despite adequate therapy. Hypoglycemic hemiplegia should be suspected in all diabetic patients using insulin or OHA with stroke-like episode, and we suggest that prolonged hypoglycemia may be related to persistence of neurologic deficits.

OBJECTIVE: To determine the relationship between cognitive-perceptual function and functional independence in stroke patients. METHOD: Thirty-three patients (16 male, 17 female) with first ever ischemic stroke were enrolled. Their mean age was 60.4 years and the mean post-onset duration was 8.1 months. Subjects underwent detailed cognitive assessment including digit span test, line bisection test, Albert test, Wechsler nonverbal memory scale, Korean Hopkins verbal learning Test, Rey complex figure test, and trail making test A. Their functional outcomes were assessed using Functional Independence Measure (FIM) and Modified Barthel Index (MBI). RESULTS: Among the cognitive subtests, Wechsler nonverbal memory scale, Albert test, and Rey complex figure test scores had significant correlation with both FIM and MBI scores. Patients with right hemispheric stroke showed significantly lower scores in line bisection test and Rey complex figure test than those with left hemispheric stroke patients. CONCLUSION: Visuospatial perception and nonverbal memory functions seemed to be two most important cognitive- perceptual domains for functional recovery of stroke patients.

Background and Objectives:
In East Asia, tuberculous pericarditis still occurs in immunocompetent patients. We aimed to investigate clinical course of tuberculous pericarditis and the trends of echocardiographic parameters for constrictive pericarditis.
Methods:
We retrospectively analyzed medical records of patients with tuberculous pericarditis between January 2010 and January 2017 in Samsung Medical Center. Treatment consists of the standard 4-drug anti-tuberculosis regimen for 6 months with or without corticosteroids. We performed echocardiography at initial diagnosis, 1, 3 and 6 months later.
Results:
Total 50 cases with tuberculous pericarditis in immunocompetent patients were enrolled. Echocardiographic finding at initial diagnosis divided into 3 groups: 1) pericardial effusion only (n=28, 56.0%), 2) effusive constrictive pericarditis (n=10, 20.0%) and 3) constrictive pericarditis (n=12, 24.0%). The proportion of patients with constrictive pericarditis decreased gradually over time. After 6 months, only 5 patients still had constrictive pericarditis. Out of the 28 patients who initially presented with effusion alone, only one patient developed constrictive pericarditis. Echocardiographic parameters representing constrictive pericarditis gradually disappeared over the follow up period. Ventricular interdependency improved significantly from 1 month follow-up, whereas septal bounce and pericardial thickening were still observed after 6 months without significant constrictive physiology.
Conclusions
Tuberculous pericarditis with pericardial effusion without constrictive physiology is unlikely to develop into constrictive pericarditis in immunocompetent hosts, if treated with optimal anti-tuberculous medication and steroid therapy. Even though there were hemodynamic feature of constrictive pericarditis, more than 80% of the patients were improved from constrictive pericarditis.
