Background: Breast cancer is the most common cancer in women worldwide with a rising incidence rate in most countries. Considering the increase in life expectancy and change in lifestyle of Iranian women, this study investigated the age-adjusted trend of breast cancer incidence during 2000-2009 and predicted its incidence to 2020. Materials and Methods: The 1997 and 2006 census results were used for the projection of female population by age through the cohort-component method over the studied years. Data from the Iranian cancer registration system were used to calculate the annual incidence rate of breast cancer. The age-adjusted incidence rate was then calculated using the WHO standard population distribution. The five-year-age-specific incidence rates were also obtained for each year and future incidence was determined using the trend analysis method. Annual percentage change (APC) was calculated through the joinpoint regression method. Results: The bias adjusted incidence rate of breast cancer increased from 16.7 per 100,000 women in 2000 to 33.6 per 100,000 women in 2009. The incidence of breast cancer had a growing trend in almost all age groups above 30 years over the studied years. In this period, the age groups of 45-65 years had the highest incidence. Investigation into the joinpoint curve showed that the curve had a steep slope with an APC of 23.4% before the first joinpoint, but became milder after this. From 2005 to 2009, the APC was calculated as 2.7%, through which the incidence of breast cancer in 2020 was predicted as 63.0 per 100,000 women. Conclusions: The age-adjusted incidence rate of breast cancer continues to increas in Iranian women. It is predicted that this trend will continue until 2020. Therefore, it seems necessary to prioritize the prevention, control and care for breast cancer in Iran.

This study examines the effect of the height of cane that hemiplegic patients due to stroke use on their plantar pressure in standing position, gait speed. The study suggests a new standard for appropriate cane height that considers the change of average height of population. Research subjects included 12 patients hospitalized in S Medical Care Hospital located in Gwangju Metropolitan City in South Korea who were diagnosed with stroke. Group A uses a cane of the height of the greater trochanter of femur, group B uses a cane of 5cm above the height of the greater trochanter of femur, and group C is a cane of 10cm above the height of the greater trochanter of femur. In the study result, non-affected side plantar pressure and affected side plantar pressure showed a significant difference among the cases where the cane height was the same as the A group, B group, C group. In the post-hoc analysis result, a significant difference was observed between the case of A group and C group. Gait speed showed no significant difference among the case of the A group, B group, C group. The asymmetry of the stroke affects not only the posture but also the walking that is related to daily life. Changes in the height of the cane did not affect walking speed. The change in the height of the cane showed a change in the weight support ratio, which is thought to have a positive effect on the asymmetry. In future clinical setting, this study result will be able to provide fundamental data regarding the cane height in the standing or walking therapy for hemiplegic patients due to stroke with cane application.

Purpose: The vancomycin dosage regimen is regularly modified according to the patient's glomerular filtration rate (GFR). In the present study, we aimed to assess the usefulness of serum cystatin C (Cys-C) concentration, compared with serum creatinine (SCr) concentration, for predicting vancomycin clearance (CLvcm) in neonates. Methods: We retrospectively analyzed the laboratory data of 50 term neonates who were admitted to the neonatal intensive care unit and received intravenous vancomycin, and assessed the pharmacokinetic profiles. Creatinine clearance (CLcr) and GFR based on Cys-C (GFRcys-c) were estimated using the Schwartz and Larsson formulas, respectively. Results: The mean CLvcm (${\pm}$standard deviation) was $74.52{\pm}31.17L/hr$, the volume of distribution of vancomycin was $0.67{\pm}0.14L$, and vancomycin half-life was $9.16{\pm}17.42hours$. The SCr was $0.46{\pm}0.25mg/dL$ and serum Cys-C was $1.43{\pm}0.34mg/L$. The peak and trough concentrations of vancomycin were $24.65{\pm}14.84$ and $8.10{\pm}5.35mcg/mL$, respectively. The calculated GFR based on serum creatinine concentration (GFR-Cr) and GFRcys-c were $70.2{\pm}9.45$ and $63.6{\pm}30.18mL/min$, respectively. The correlation constant for CLvcm and the reciprocal of Cys-C (0.479, P=0.001) was significantly higher than that for CLvcm and the reciprocal of SCr (0.286, P=0.044). GFRcys-c was strongly correlated with CLvcm (P=0.001), and the correlation constant was significantly higher than that for CLvcm and CLcr (0.496, P=0.001). Linear regression analysis showed that only GFRcys-c was independently and positively correlated with CLvcm (F=41.9, P<0.001). Conclusion: The use of serum Cys-C as a marker of CLvcm could be beneficial for more reliable predictions of serum vancomycin concentrations, particularly in neonates.

Purpose: This study reports the clinical features of infant, child, school aged and adolescent patients treated for acute poisoning in nationwide emergency departments (EDs). Methods: We retrospectively analyzed clinical data pertaining to patients under 19 years of age who were treated for acute poisoning in nationwide EDs from 2013 to 2015. The data were collected by the National Emergency Department Information System (NEDIS). All patients were divided into three groups: 'Infant and child group' (0 to 5 years), 'school age group' (6 to 12 years) and 'adolescent group' (13 to 18 years). General characteristics, Korea Standard Classification of Disease $7^{th}$ (KCD-7) codes and results of care were collected. Results: There were 14,500 pediatric poisoning cases during the study period. The distribution of patient age was bimodal with two peaks among infant, child and adolescent group. The proportion of alert mentality at the ED visit of the infant and child group was 99.3%, while that of the adolescent group was 86.4%. The proportion of intentional intoxication was higher in the adolescent group (40.7%) than other age groups. Among children less than 13 years of age, various poisonous substances and therapeutic drugs were common. Conclusion: There were some clinical differences in acute poisoning patients between age groups. It is necessary to establish a preventive plan considering characteristics by age. Since the KCD-7 code has limitations in analyzing the characteristics of poisoning patients, it is necessary to consider the registration system of poisoning patients.

Purpose: The aim of this study was to characterize Korean patients with Fanconi anemia (FA), which is a rare but very challenging genetic disease. Methods: The medical records of 12 FA patients diagnosed at Chonnam National University Hospital from 1991 to 2012 were retrospectively reviewed. Results: The median age at diagnosis was 6.2 years. All patients showed evidence of marrow failure and one or more physical stigmata. Chromosome breakage tests were positive in 9 out of 11 available patients. The median follow-up duration was 69.5 months. The Kaplan-Meier (KM) survival of all patients was 83.3% at 10 years and 34.7% at 20 years, respectively. Seven patients underwent 9 stem cell transplantations (SCTs). Among them, 5 were alive by the end of the study. Ten-year KM survival after SCT was 71.4% with a median follow-up of 3.4 years. All 5 patients treated with supportive treatment alone died of infection or progression at the median age of 13.5 years, except for one with short followup duration. Acute leukemia developed in 2 patients at 15.4 and 18.1 years of age. Among 6 patients who are still alive, 3 had short stature and 1 developed insulin-dependent diabetes mellitus. Conclusion: We provide information on the long-term outcomes of FA patients in Korea. A nation-wide FA registry that includes information of the genotypes of Korean patients is required to further characterize ethnic differences and provide the best standard of care for FA patients.

In this research, the degree of depression and death orientation of the 332 female students majoring in dental hygiene at colleges located in Gyeongsangbuk-do Province were examined and analyzed through a structured self-administered questionnaire from May to July, 2012, for the purpose of improving their mental health. The results are as follows: 1. The degree of depression of the subject students majoring in dental hygiene was shown that 59.9%, 36.8%, 3.0%, and 0.3% of the students were in the normal group, mild depression group, moderate level of depression group, and severe depression group, respectively. 2. The grand mean and the standard deviation of the subjects'death orientation was $2.09{\pm}0.62$ points. 3. The degree of depression of the subjects whose family's economic level was low, whose satisfaction with their family background was low, whose satisfaction level with their major was low, whose school records was low, who frequently thought about death, and who attempted suicide was high in a meaningful way, and death orientation was meaningfully low. In addition, those in the group with the experience of feeling suicidal were proved to have a significantly high degree of depression, and those without the experience of education about death had a low level of death orientation. 4. The degree of depression and death orientation had a positive correlation. When the study results above are combined, follow-up research needs to be conducted so that differentiated programs linked with the care for mental health for the formation of proper attitudes toward depression and death will be established to help students lead a positive life.

The goal of this study was to analyze the demands of parents of an after-school program. In order to do this, we looked at cultural centers and their curriculums. Cultural centers are one of the most popular private education centers for preschoolers, and are used for the operation of special activities. The research was conducted on preschool curriculums of 300 cultural centers, including cultural centers of department stores and supermarkets. The curriculum analysis was conducted for 400 preschool curriculums of three cultural centers, which had the most programs of all. The scope of the curriculum analysis was based on the 3rd Childcare Standard Curriculum for infants and Nuri Curriculum for preschoolers. As a result of the analysis, there were 12,286 programs for infants. The most popular topics for programs were comprehensive activity, physical activity, and music activity. There were 15,310 programs for preschoolers. Physical activity was the most popular topic among them. It was followed by drawing activity and number and operating activity. Analyzing the contents of these programs, we found that 'participating in physical activity' of physical exercise, and 'expressing artistically' of artistic experience were the most popular contents of infants. 'Expressing artistically' of artistic experience and 'control of body and basic exercise' of physical exercise were most popular contents for preschoolers. The results show that parents demand physical activity programs for infants and artistic activity programs for preschoolers. The results of the research should be considered when childcare centers try to make a special after-school program.
