We studied the intradural variations of spinal nerve rootlets in 100 cases of Korean adults. The results of the study are as follows ; 1. The incidence of intrasegmental variations (abberrant rootlets) is high in cervical segments and decreased toward lumbosacral segments. The incidence is higher in posterior rootlets than anterior, except cervical sesments. 2. The incidence of intersegmental variations is higher in posterior rootlets than anterior, and generally high in cervical and lumbar segments. 3. We divide the intersegmental variations into supernumerary rootlets, dividing rootlets, and anastomosing rootlets, and among them the incidence of anastomosing rootlets is higher. We divide the anastomosing rootlets into parallel anastomosing rootlets, uniting anastomosing rootlets, and rearrangement anastomosing rootlets. 4. The anterior to posterior anastomosing of spinal nerve rootlet is present in 4 of cases studied.

BACKGROUND AND OBJECTIVES: The incidence of inflammatory heart diseases is not yet as high as those of other cardiovascular diseases; however, inflammatory heart diseases do have relatively high mortality rate. Therefore, update information on the economic burden of inflammatory heart diseases are necessary in order to appropriate policy making on these diseases. MATERIALS AND METHODS: This study used a number of resources to obtain data, national health insurance statistics, the Korean Health Panel, and the causes of death report by the Korean National Statistical Office. The total costs of inflammatory heart diseases were estimated as the sum of direct medical care costs, direct non-medical care and indirect costs. RESULTS: The total direct cost of inflammatory heart disease was higher in Korean men than that of Korean women and cost due to inpatient was higher than that of outpatients cost. The costs to cover premature death were highest among all of the components used to determine the total costs for inflammatory heart disease, representing 66.3% of these costs in Korea. CONCLUSION: Inflammatory heart disease has a relatively high mortality rate, and the costs that are associated with premature deaths consume the greatest proportion of the costs associated with this disease. In spite of some limitations of study, this could be a reliable evidence of economic burden of inflammatory heart disease.

Torsade de pointes is a life-threatening, polymorphic ventricular tachycardia associated with prolongation of the QTc interval. Although torsade de pointes is found in many clinical settings, it is mostly drug induced. Similar problems have been described with nonsedating H1-selective antihistamines like terfenadine and astemizole. The increased risks of both H1-antihistamines were associated with exposure to supratherapeutic doses or concomitant exposure to the cytochrome P-450 inhibitors, ketoconazole, erythromycin and cimetidine. We report a 51-year-old woman with torsade de pointes and a long QTc interval caused by the combined use of terfenadine and itraconazole. After discontinuation of these drugs and treatments with electrical cardioversion and magnesium sulfate, torsade de pointes and prolonged QTc interval were no longer observed and she was discharged in good condition with a normal ECG. In conclusion, physicians should be aware that terfenadine and astemizole can cause torsade de pointes in rare cases.

OBJECTIVES: According to the World Health Organization, there have been frequent reports of Ebola virus disease (EVD) since the 2014 EVD pandemic in West Africa. We aim to estimate the outbreak scale when an EVD infected person arrives in Korea. METHODS: Western Africa EVD epidemic mathematical model SEIJR or SEIJQR was modified to create a Korean EVD outbreak model. The expected number of EVD patients and outbreak duration were calculated by stochastic simulation under the scenarios of Best case, Diagnosis delay, and Case missing. RESULTS: The 2,000 trials of stochastic simulation for each scenario demonstrated the following results: The possible median number of patients is 2 and the estimated maximum number is 11 when the government intervention is proceeded immediately right after the first EVD case is confirmed. With a 6-day delay in diagnosis of the first case, the median number of patients becomes 7, and the maximum, 20. If the first case is missed and the government intervention is not activated until 2 cases of secondary infection occur, the median number of patients is estimated at 15, and the maximum, at 35. CONCLUSIONS Timely and rigorous diagnosis is important to reduce the spreading scale of infection when a new communicable disease is inflowed into Korea. Moreover, it is imperative to strengthen the local surveillance system and diagnostic protocols to avoid missing cases of secondary infection.

Objective: N-terminal pro-B-type natriuretic peptide (NT-proBNP) is suggested as a prognostic biomarker for communityacquired pneumonia (CAP). However, its predictive value for an individual adult and elderly CAP patients has not been fully investigated. Methods: Patients with CAP aged 18 years and older, who visited the emergency department (ED) from March 1, 2016 to March 31, 2019, were included in this study. Patients were divided into the adult group and the elderly group (age ≥70 years). Data was collected from the ED-based registry, and medical charts were retrospectively reviewed. The registry data included sociodemographic and past medical characteristics, as well as laboratory findings including NT-proBNP and C-reactive protein (CRP), Pneumonia Severity Index (PSI), and CURB65 (confusion, urea, respiratory rate, blood pressure, and aged 65 or more). The independent potential of NT-proBNP to predict mortality was assessed in both groups using multivariable logistic regression, and its predictive ability was evaluated in terms of performance (using areas under the curve [AUCs]) and goodness-of-fit (using the Bayesian information criterion [BIC]). Results: Totally, 325 CAP patients were evaluated, of which 208 (64%) belonged to the elderly group. NT-proBNP was identified as an independent predictor of CAP mortality in elderly patients, but not in adult patients. Moreover, AUC of the NT-proBNP for mortality was comparable to AUC of the PSI, but was higher than that of the CURB65, in elderly CAP patients. Similarly, the NT-proBNP had a better overall fit (lower BIC value) compared to the CURB65, for mortality. Additionally, both AUC and overall fit of the NT-proBNP for mortality were significantly superior to values obtained for CRP. Conclusion For elderly CAP patients in the ED, the NT-proBNP is an independent and useful predictor of mortality.

Objective: This study investigated the associations between paraspinal muscle measurements on chest computed tomography and clinical outcomes of elderly patients with community-acquired pneumonia (CAP). Methods: This single-center, retrospective, observational study analyzed elderly patients (≥65 years) with CAP hospitalized through an emergency department between March 2020 and December 2022. We collected their baseline characteristics and laboratory data at the time of admission. The paraspinal muscle index and attenuation were calculated at the level of the 12th thoracic vertebra using chest computed tomography taken within 48 hours before or after admission. Univariable and multivariable logistic regression analyses were conducted to evaluate the association between paraspinal muscle measurements and 28-day mortality. Receiver operating characteristic (ROC) curve and area under the curve (AUC) analyses were used to evaluate the prognostic predictive power. Results: Of the 338 enrolled patients, 60 (17.8%) died within 28 days after admission. A high paraspinal muscle index was associated with low 28-day mortality in elderly patients with CAP (adjusted odds ratio, 0.994; 95% confidence interval, 0.992–0.997). The area under the ROC curve for the muscle index was 0.75, which outperformed the pneumonia severity index and the CURB-65 (confusion, urea, respiratory rate, blood pressure, age ≥65 years) metric, both of which showed an AUC of 0.64 in predicting mortality. Conclusion A high paraspinal muscle index was associated with low 28-day mortality in patients aged 65 years or older with CAP.

Objective: Body mass index (BMI) is a major determinant of N-terminal pro-brain natriuretic peptide (NT-proBNP). However, the relationship of BMI with pneumonia has not been entirely characterized. Methods: Adult patients with pneumonia, who visited the emergency department from January 2017 to December 2019, were included. According to BMI, they were divided into two groups, including normal-weight and obesity groups. Data were retrospectively reviewed via the prospectively collected pneumonia registry and medical chart. NT-proBNP, BMI and pneumonia severity index (PSI) were determined for all subjects. The moderating effect between NT-proBNP and BMI was examined by entering interaction terms into the multivariable regression model predicting mortality. Using the area under the curve (AUC), the predictive performance of NT-proBNP was evaluated. Results: Of 327 enrolled patients, 118 patients belonged to the obesity group. In a multivariable model including BMI, NT-proBNP was identified as an independent predictor of mortality. The AUC of the adjusted NT-proBNP including BMI, significantly increased the AUC of the adjusted NT-proBNP excluding BMI and tended to be superior to that of PSI. A positively significant BMI-by-NT-proBNP interaction for mortality was observed. NT-proBNP showed significant prognostic power in both BMI groups, but NT-proBNP of the obesity group had significantly higher AUC than that of the normalweight group. In the obesity group, the AUC of NT-proBNP tended to be higher than that of PSI. Conclusion BMI is a significant factor enhancing the prognostic power of NT-proBNP in pneumonia. The prognostic utility of NT-proBNP was significantly differed by BMI groups, which is more useful in the obesity group than the normalweight group.

BACKGROUND: Recently, physicians have been challenged to see more patients per office session while maintaining patient satisfaction. We examined the variables related to patient satisfaction with the time spent with physician during office visit. METHODS: In the department of family medicine of an university hospital, a trained researcher observed patient visits by VTR and collected additional data using medical record reviews and patient exit questionnaires from July 1 to July 31, 2002 The data was analyzed statistically by SPSS ver11.0/PC . RESULTS: Visits by 103 patients were observed in this study. Age, functional health status, time of Dr.'s talking to patients and the ratio of Dr.'s talking time to visit length were significantly associated with patient satisfaction (P<0.05). Sex, marital status, education level, new vs. established patient, reason for visit, visit length, number of problems, number of medications, body mass index, and satisfaction for time spent were not significantly associated with patient satisfaction. According to logistic regression analysis, greater patient satisfaction were associated with better perceived health status, with more ratio of Dr.'s talking time to visit length and with age younger than 40 years. CONCLUSION: Physician can enhance patient satisfaction during an office visit by spending sufficient time to talk with patients during each visit and should take an interest in elderly patients and patients with multiple problems.
