Restoration of ambulation is important for stroke patients. Valid and reliable methods are required for the assessment of lower limb functional status. We reviewed the psychometric properties of methods employed to assess lower extremity motor function, ambulation, and balance, with a focus on stroke patients. We define “motor function” as the ability to produce bodily movements when the brain, motor neurons, and muscles interact. “Ambulation” is defined as the ability to walk with or without a personal assistive device, and “balance” as the ability to maintain stability (without falling) during various physical activities. The Motricity Index and Fugl-Meyer Assessment of Lower Extremities assess the motor function of the lower limbs. The Functional Ambulation Category, 10-m Walk Test, and 6-minute Walk Test assess ambulation. The Berg Balance Scale, Timed Up and Go Test, Functional Reach Test, and Trunk Impairment Scale explore balance. All these tests exhibit high-level validity and have good inter-rater and test-retest reliabilities. However, only 3 methods have been formally translated into Korean. The methods discussed here can be used for standardized assessment, personalized goal setting, rehabilitation planning, and estimation of therapeutic efficacy.

Transient myeloproliferative disorder (TMD), which may mimic acute leukemia, occurs in neonates with Down syndrome along with hepatic fibrosis. TMD is recognized shortly after birth or in the neonatal period and is characterized by leukocytosis and thrombocytopenia, which resolve spontaneously in four to six weeks. And hepatic fibrosis is characterized by diffuse intralobular sinusoidal fibrosis, extramedullary hematopoiesis and hemochromatosis. A newborn male infant with Down syndrome, atrial septal defect and ventricular septal defect is reported. He showed abnormal myelopoiesis accompanying characteristic hepatic sinusoidal fibrosis. Knowing the cellular mechanism of hepatic fibrosis and its modulation by growth factors, a pathogenetic link between transient myeloproliferative disorder and the development of liver fibrosis in Down syndrome neonates, association of this triad no longer appears to be accidental.

PURPOSE: This study was done to evaluate the usefulness of preoperative computed tomography (CT) and intraoperative laparoscopic ultrasound to facilitate treatment of gastric submucosal tumors. MATERIALS AND METHODS: The feasibility of laparoscopic wedge resection as determined by CT findings of tumor size, location, and growth pattern was correlated with surgical findings in 89 consecutive operations. The role of laparoscopic ultrasound for tumor localization was analyzed. RESULTS: Twenty-three patients were considered unsuitable for laparoscopic wedge resection because of large tumor size (N=13) or involvement of the gastroesophageal junction (N=9) or pyloric channel (N=1). Laparoscopic wedge resection was not attempted in 11 of these patients because of large tumor size. Laparoscopic wedge resection was successfully performed in 65 of 66 (98.5%) patients considered suitable for this procedure. Incorrect interpretation of preoperative CT resulted in a change of surgery type in seven patients (7.9%): incorrect CT diagnosis on gastroesophageal junction involvement (N=6) and on growth pattern (N=1). In 18 patients without an exophytic growth pattern, laparoscopic ultrasound was necessary and successfully localized all lesions. CONCLUSIONS: Preoperative CT and laparoscopic ultrasound are useful for surgical planning and tumor localization in laparoscopic wedge resection.

PURPOSE: The aim of the study was to identify the relationships among age, activities of daily living and health-related quality of life (HRQoL) for centenarians in Busan. METHODS: Forty-nine centenarians (2 males and 47 females) participated in the study, done from April to July, 2006. Pace-to-face interviews were used to collect data. Activities of daily living were measured using K-ADL, K-IADL and health-related quality of life, using the Short Form Health Survey (SF-36). RESULTS: Over 50% of the centenarians reported independence for six-items but not for bathing. With regard to type of dependency, 77.6% were independent in transferring, 71.4%, in using the toilet, 67.3%, in feeding and in continence and 57.1% in dressing but just 24.5% were independent in bathing. Age was significantly associated with K-IADL (r= -.303, p= .03). The centenarians were more impaired in physical health components compared to mental health components for health-related quality of life. CONCLUSION: These results may contribute to a better understanding of activities of daily living and health-related quality of life of centenarians. The findings are relevant to health professionals, in particular professionals who are developing wellness programs to optimize health-related quality of life and functional status for the extremely old age population.

INTRODUCTION: We investigated sex and ethnic differences in the incidence, clinical characteristics and 1-year mortality of patients with newly diagnosed AF in a multi-ethnic population. METHOD: This retrospective cohort study of patients diagnosed with AF from 2008 to 2015 was based on medical claims, casemix and subvention data submitted to the Ministry of Health. Patients with AF were matched with controls without AF for age (3-year bands), sex and ethnicity, and categorised as middle-aged (45-64 years) or elderly (≥65 years) among major ethnic groups in Singapore (Chinese, Malay and Indian). RESULTS: Among 40,602 adults with AF (elderly 74%), Malays had the highest age-standardised incidence rate of AF, followed by Chinese and Indians; and the rate was higher in men. Despite having the worst cardiovascular risk profile, Indians had the lowest prevalence and incidence of AF. The 1-year mortality rate after newly diagnosed AF was 22-26 deaths per 100 people. Newly diagnosed AF was independently associated with increased 1-year all-cause mortality among middle-aged (adjusted odds ratio [AOR] 9.08, 95% confidence interval [CI] 7.36-11.20) and elderly adults (AOR 3.60, 95% CI 3.40-3.80) compared with those without AF. Sex differences in mortality among patients with AF were limited to elderly adults (men: AOR 1.17, 95% CI 1.11-1.24), while Indians were associated with a 30% increased odds of mortality compared with Chinese regardless of age (middle-aged: AOR 1.27, 95% CI 1.09-1.548 elderly: AOR 1.33, 95% CI 1.22-1.45). CONCLUSION Variations in incidence, clinical profile and 1-year mortality of patients with AF in a nationwide cohort were influenced by sex and ethnicity. Newly diagnosed AF portends a worse prognosis and is a marker of high mortality within the first year.
