A 68-year-old man presented with progressive impairment of gait, balance, and memory. He exhibited a slow and unstable gait. Formal neuropsychological evaluation showed a deficit in visuospatial function and memory with frontal dysfunctions. He was diagnosed as idiopathic normal pressure hydrocephalus with an Evans' ratio of 0.35. Four-and-a-half years after ventriculoperitoneal shunt placement, he showed a marked improvement in gait, as well as in visuospatial and frontal lobe functions. He benefited from shunt surgery for at least four-and-a-half years.

Medicine is the practice that occurs in the context of the society. It requires interaction with individual patients, fellow doctors and other health care professionals, health care officials, public, institution, and the society as a whole. To date, medical practice in Korea has largely been concentrated on applying biomedical knowledge and skill to a patient. We defines 'social competency' as 'competency for medicine as a social institution.' This survey aims to grasp the current situation of Korean doctors' perception on social competency, in terms of necessity, satisfaction, learning experience, and possible intervention. Respondents generally recognized the necessity of social competencies but were not satisfied with their demonstration of those competencies. Competencies for 'understanding on law and institution' and 'communication' were perceived highly necessary. General satisfaction and each satisfaction rate on individual competencies were all below 'neutral,' showing their dissatisfaction. Especially, doctors assess their fellow doctors' competencies for 'understanding on law and institution' and 'understanding on human being and society' at the lowest level. The mismatch between perceived necessity and satisfaction shows the legitimate ground for educational intervention. The proportions of respondents who have learned on each domain of social competency were all below 70%. Learning experience on self-management and leadership was the least. Among possible remedy for low social competency, respondents perceived 'improvement on national health insurance' and 'improvement on resident training program' as the most urgently needed. The data from this preliminary survey can be utilized for educational and institutional intervention in the future.

BACKGROUND: We investigated the associations between mineral metabolism parameters and mortality to identify optimal targets in Korean hemodialysis patients. METHODS: Among hemodialysis patients registered in the end-stage renal disease registry of the Korean Society of Nephrology between March 2012 and June 2017, those with serum calcium, phosphorus, and intact parathyroid hormone (iPTH) measured at enrollment were included. Association of serum levels of calcium, phosphorus, and iPTH with all-cause mortality was analyzed. RESULTS: Among 21,433 enrolled patients, 3,135 (14.6%) died during 24.8 ± 14.5 months of follow-up. After multivariable adjustment, patients in the first quintile of corrected calcium were associated with lower mortality (hazard ratio [HR], 0.84; 95% confidence interval [95% CI], 0.71–0.99; P = 0.003), while those in the fifth quintile were associated with higher mortality (HR, 1.39; 95% CI, 1.20–1.61; P < 0.001) compared with those in the third quintile. For phosphorus, only the lowest quintile was significantly associated with increased mortality (HR, 1.24; 95% CI, 1.08–1.43; P = 0.003). The lowest (HR, 1.18; 95% CI, 1.02–1.36; P = 0.026) and highest quintiles of iPTH (HR, 1.24; 95% CI, 1.05–1.46; P = 0.013) were associated with increased mortality. For target counts achieved according to the Kidney Disease Outcomes Quality Initiative guideline, patients who did not achieve any mineral parameter targets hadhigher mortality than those who achieved all three targets (HR, 1.37; 95% CI, 1.12–1.67; P = 0.003). CONCLUSION: In Korean hemodialysis patients, high serum calcium, low phosphorus, and high and low iPTH levels were associated with increased all-cause mortality.
