  • Objectives: The objective of this study was to retrospectively investigate the association of diseases having an influence on inhibition of angiogenesis such as hypertension, diabetes mellitus type II, hypercholesterolemia, and rheumatoid arthritis (RA) with the development of osteonecrosis of the jaws. Materials and Methods: The 135 patients were allocated into 4 groups of bisphosphonate-related osteonecrosis of the jaw (BRONJ) group (1A); non-BRONJ group (1B); osteonecrosis of the jaw (ONJ) group (2A); and control group (2B), according to histologic results and use of bisphosphonate. This retrospective study was conducted with patients who were treated in one institute from 2012 to 2013. Fisher's exact test and logistic regression analysis were used to analyze the odds ratios of diseases having an influence on inhibition of angiogenesis for development of ONJ. Results: The effects of diabetes and hypertension were not statistically significant on development of ONJ. When not considering bisphosphonate use, RA exhibited a high odds ratio of 3.23 (P=0.094), while hyperlipidemia showed an odds ratio of 2.10 (P=0.144) for development of ONJ. More than one disease that had an influence on inhibition of angiogenesis showed a statistically significant odds ratio of 2.54 (P=0.012) for development of ONJ. Conclusion: Patients without diseases having an influence on inhibition of angiogenesis were at less risk for developing ONJ.

  • The purpose of this retrospective study was to evaluate the effects of diagnostic sonography in pediatric patients with inguinal hernias. The patients were classified into two groups. Group A included the patients who had been operated upon for inguinal hernia in 1980's, when diagnostic sonography was not available. Group B included the patients, operated upon for inguinal hernia from 2001 to 2002, when inguinal sonography was employed to detect potential bilateral hernias. The age distribution, sex ratio, laterality, bilaterality, and concomitant symptoms were compared between group A and group B. There were 296 cases in group A and 377 cases in group B. The prevalent age group was from 1 to 5 years. There was no difference in age group distribution between both groups. The male to female ratio was 5.3:1 in group A and 3.5:1 in group B. The ratio of unilateral to bilateral hernia was 5:1 in group A and 3:1 in group B. In cases with a unilateral hernia, the ratio of right to left was 1.5:1 in group A and 1.8:1 in group B. In cases with bilateral hernia, the simultaneous bilateral hernia was 33 cases (67.4 %) in group A and 75 cases (80.6 %) in group B. The sequential bilateral hernia was 16 cases (32.7 %) in group A and 18 cases (19.4 %) in group B. Although the ratio of bilateral hernia was increased in group B, the portion of the sequential bilateral hernia was significantly decreased in group B. In conclusion, there were no differences in the age distribution and the laterality between group A and B. The ratio of female patients and the incidence of bilateral hernia were increased in group B even though the portion of the sequential bilateral hernia was decreased. This result shows that the preoperative inguinal sonography in unilateral hernia with potential bilateral hernia is useful in early detection of the sequential contralateral hernia.

  • Purpose: The purpose of this study was to summarize trends and status of nursing research utilizing experimental designs in the Journal of Rheumatology Health over the past 10 years. Method: The Journal of Rheumatology Health published 37 experimental research articles between 1994 and 2004. These articles were included in a retrospective descriptive analysis. A checklist was utilized for data collection. Results: Qoasi-experimental researches were more frequent than pre-experimental research, but there were 8 research studies which had no hypothesis. The most frequently used nursing interventions were exercise/movement, and cognitive, followed by sensitive, and social interventions. There were very few research studies that used random assignment for internal validity. The rate of effectiveness of self-help interventions was lower than socio-psychological, cognitive, or motor-physical interventions. There was no research regarding families of patients with rheumatoid disease. Conclusion: Rigorous experimental research design is needed for internal and external validity in future research. Generalizing the effects of nursing interventions that are the results of rigorous experimental designs will contribute to promote the quality of life of patients with rheumatism and their families.

  • Objectives The purpose of this study is to evaluate the effect of herbal medicine in children's growth. Methods 51 children from the age of 5 to 16 were participated in this study (27 of boys and 24 of girls). The participants were from the department of the pediatrics in Daegu hanny university oriental medical hospital. They were measured their body composition and their bone age, the height percentile of their first and the last visit. Then, those were compared by the Korean Association of Pediatrics' Growth Statistics Curve. Results 1. Generally, total children's average height and weight were significantly increased after the herbal medical treatment. The differences between their height and the general populations' average height, their weight and general populations' average weight were significantly decreased after the treatment. 2. Total children's average soft lean mass, body fat mass, BMI were also significantly increased after the herbal medical treatment. 3. The mean height percentiles of the children has increased by 1.47 percentile. The mean weight percentiles of the children decreased 1.08 percentile. 4. The height percentiles were increased in every group except the group of boys younger than 9 and older than 12 year old. Other than the group of boys younger than 9-year-old and the group of 10-11-year-old boys, every group showed decreasing weight percentile. Conclusions The herbal medical treatment helped children with growth retardation.

  • Purpose: The aims of this study were to evaluate the safety and pharmacokinetics of levetiracetam (LEV) in neonates with seizures and to establish a population pharmacokinetics (PPK) model by using the software NONMEM. Methods: A retrospective analysis of 18 neonatal patients with seizures, who were treated with LEV, including 151 serum samples, was performed. The mean loading dose was 20 mg/kg, followed by a mean maintenance dose of 29 mg/kg/day. Results: Seventeen neonates (94%) had seizure cessation within 1 week and 16 (84%) remained seizure-free at 30 days under the LEV therapy. The mean serum concentration of LEV was $8.7{\mu}g/mL$. Eight samples (5%) were found above the therapeutic range. No serious adverse effects were detected. In the PPK analysis for Korean neonates, the half-life was 9.6 hours; clearance, 0.357 L/hr; and volume of distribution, 4.947 L, showing differences from those in adults. Conclusion: LEV is a safe and effective option for the treatment of neonatal seizures with careful therapeutic drug monitoring.

  • Objectives: Smoking cessation decreases morbidity and mortality due to chronic obstructive pulmonary disease (COPD). Pharmacotherapy for smoking cessation is highly effective. However, the optimal prescription rate of smoking cessation medications among smokers with COPD has not been systemically studied. The purpose of this study was to estimate the national prescription rates of smoking cessation medications among smokers with COPD and to examine any disparities therein. Methods: We conducted a retrospective study using National Ambulatory Medical Care Survey data from 2007 to 2012. We estimated the national prescription rate for any smoking cessation medication (varenicline, bupropion, and nicotine replacement therapy) each year. Multiple survey logistic regression was performed to characterize the effects of demographic variables and comorbidities on prescriptions. Results: The average prescription rate of any smoking cessation medication over 5 years was 3.64%. The prescription rate declined each year, except for a slight increase in 2012: 9.91% in 2007, 4.47% in 2008, 2.42% in 2009, 1.88% in 2010, 1.46% in 2011, and 3.67% in 2012. Hispanic race and depression were associated with higher prescription rates (odds ratio [OR], 5.15; 95% confidence interval [CI], 1.59 to 16.67 and OR, 2.64; 95% CI, 1.26 to 5.51, respectively). There were no significant differences according to insurance, location of the physician, or other comorbidities. The high OR among Hispanic population and those with depression was driven by the high prescription rate of bupropion. Conclusions: The prescription rate of smoking cessation medications among smokers with COPD remained low throughout the study period. Further studies are necessary to identify barriers and to develop strategies to overcome them.

  • Background Chloral hydrate (CH) is the primary agent most commonly used for pediatric sedation prior to diagnostic, therapeutic procedures. In the management of pediatric facial laceration, the initial dose of CH has to balance the need for adequate sedation against the need to minimize sedative complications. Methods A retrospective review of medical records of 834 children who visited our emergency room for facial lacerations from August 2010 to September 2012 was conducted. They were divided into six groups on the basis of the initial dose of CH administered. Further, each group was compared with the standard group (70 to ${\leq}80mg/kg$) with respect to sedation success, augmentation dose, failed sedation, time to procedure, and time of stay. Results With respect to the complication rate, only group 1 (range, 40 to ${\leq}50mg/kg$) showed a significantly lower complication rate. In the case of all the other variables considered, there were no significant differences among any of the groups. Conclusions An initial CH dose of $48{\pm}2mg/kg$ does not negatively affect the success rate of sedation or the need for additional sedative during the primary closure of facial lacerations in pediatric patients. Further, lower doses reduce the incidences of adverse effects and do not delay procedure readiness. Therefore, $48{\pm}2mg/kg$ of CH can be considered the optimal initial dose for pediatric sedation.

  • Background: Neuroendocrine tumors have widespread and different clinical presentations and prognoses. This study was conducted to assess their survival time and prognostic factors in Iran. Materials and Methods: In a retrospective cohort study, 189 patients diagnosed of having neuroendocrine carcinoma were chosen. The tumor and clinical characteristics of the patients were modeled with a Cox proportional hazard approach. Survival was assessed using Kaplan-Meyer curves. Results: Crude median survival time was 30 months. Women survived longer than men (the median survival time for women was 40 and for men was 24 months). Age (<60 vs >60 years old with hazard ratio (HR) of 2.43, 95% CI 1.3-4.5), primary pathology report (carcinoid vs. others with HR 5.85 cm, 95% CI 2.4-14.3), tumor size cm (for 5-10, HR of 3.1, 95% CI 1.6 and for >10 HR of 8.2, 95% with 95% CI 3.1-21.9), and chemotherapy with single drug (taking vs. not taking with a HR 2.2, 95% CI 1.1-4.8) had significant effects on overall survival of patients. Conclusions: Survival time in patients with neuroendocrine carcinomas is related to demographics, clinical characteristics, tumor histology, and subtype specific treatment.

  • Background Skin cancer is the most common malignant tumor in humans. Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are the two most common types of skin cancers. When skin cancer is clinically suspected, preoperative biopsies are recommended for a definite diagnosis. However, despite a concern over potential increased risk of metastasis associated with mechanical manipulation, there have been few investigations into whether a preoperative biopsy affected the recurrence of BCC and SCC. Methods Primary BCC or SCC patients who underwent standard surgical excision from 1991 to 2010 were reviewed and a retrospective analysis was performed. Ultimately, 45 BCC patients and 54 SCC patients, who did not meet the exclusion criteria, were analyzed. To identify whether a preoperative biopsy affected the recurrence of BCC and SCC, the recurrence rates of each with and without biopsy were compared. Results Preoperative biopsy had no statistically significant effect on recurrence (BCC, P=0.8680; SCC, P=0.7520). Also, there was no statistical significance between the interval from initial biopsy to first operation and recurrence (BCC, P=0.2329; SCC, P=0.7140). Even though there was no statistical significance, the mean interval from the biopsy to the operation among the BCC patients who underwent preoperative biopsy was 9.2 months in those who had recurrence and 2.0 months in those who had no recurrence. Conclusions There was no statistically significant relationship between preoperative biopsy and recurrence of BCC and SCC. However, there was a tendency toward recurrence in patients with a longer interval between the biopsy and the corrective operation in BCC.

  • Objectives: There have been many studies reporting the clinical value of Euphorbia kansui Radix or Melonis Calyx, but few systematic studies of the changes that may occur after taking such herbal medication. This study aimed to investigate the characteristics of the patient group, possible changes in blood test and InBody test results, and to discover the current state and future direction of clinical use of Euphorbia kansui Radix or Melonis Calyx. Methods: This study investigated patients who were hospitalized at Kyung-Hee University Korean Medicine Hospital for at least two days from 1 March 2016 to 1 March 2019, specifically evaluating patients aged 19 and over who underwent blood tests, including an electrolyte test and an InBody test before and after taking Euphorbia kansui Radix or Melonis Calyx. Results: Among a total of 134 patients, 72 patients (53.7%) were treated with Euphorbia kansui Radix and 62 patients (46.3%) were treated with Melonis Calyx, in the context of previously diagnosed abnormal weight gain. Laboratory findings were that Na and K levels were significantly reduced in both groups. In an InBody test, body mass index (BMI), intracellular water, extracellular water, protein, mineral, and skeletal muscle were significantly reduced in both groups. Conclusions: From these results, we suggest that, although Euphorbia kansui Radix and Melonis Calyx may not induce serious adverse effects, attention should be paid to the electrolyte level with the use of these treatments. In terms of syndrome differentiation, more clinical uses will be available in the future.
