Growth charts are curves or tables that facilitate the visualization of anthropometric parameters, and are widely used as an important indicator when evaluating the growth status of children and adolescents. The latest version of the Korean National Growth Charts released in 2007 has raised concerns regarding the inclusion of data from both breastfed and formula-fed infants, higher body mass index (BMI) values in boys, and smaller 3rd percentile values in height-for-age charts. Thus, new growth charts have been developed to improve the previous version. The 2006 World Health Organization Child Growth Standards, regarded as the standard for breastfed infants and children, were introduced for children aged 0–35 months. For children and adolescents aged 3–18 years, these new growth charts include height-for-age, weight-for-age, BMI-for-age, weight-for-height, and head circumference-for-age charts, and were developed using data obtained in 1997 and 2005. Data sets and exclusion criteria were applied differently for the development of the different growth charts. BMI-for-age charts were adjusted to decrease the 95th percentile values of BMI. Criteria for obesity were simplified and defined as a BMI of ≥95th percentile for age and sex. The 3rd percentile values for height-for-age charts were also increased. Additional percentile lines (1st and 99th) and growth charts with standard deviation lines were introduced. 2017 Korean National Growth Charts are recommended for the evaluation of body size and growth of Korean children and adolescents for use in clinics and the public health sector in Korea.

Severe acute pancreatitis (SAP) is associated with systemic complications and high mortality rate in dogs. Mesenchymal stem cells (MSCs) have been investigated for their therapeutic potential in several inflammation models. In the present study, the effects of canine adipose tissue-derived (cAT)-MSCs in a rat model of SAP induced by retrograde injection of 3% sodium taurocholate solution into the pancreatic duct were investigated. cAT-MSCs labeled with dioctadecyl-3,3,3′-tetramethylindo-carbocyanine perchlorate (1 × 10⁷ cells/kg) were systemically administered to rats and pancreatic tissue was collected three days later for histopathological, quantitative real-time polymerase chain reaction, and immunocytochemical analyses. Greater numbers of infused cAT-MSCs were detected in the pancreas of SAP relative to sham-operated rats. cAT-MSC infusion reduced pancreatic edema, inflammatory cell infiltration, and acinar cell necrosis, and decreased pancreatic expression of the pro-inflammatory cytokines tumor necrosis factor-α, interleukin (IL)-1β, -6, -12, -17, and -23 and interferon-γ, while stimulating expression of the anti-inflammatory cytokines IL-4 and IL-10 in SAP rats. Moreover, cAT-MSCs decreased the number of clusters of differentiation 3-positive T cells and increased that of forkhead box P3-positive T cells in the injured pancreas. These results indicate that cAT-MSCs can be effective as a cell-based therapeutic strategy for treatment of SAP in dogs.

Based on their ability to differentiate into multiple cell types including hepatocytes, the transplantation of mesenchymal stem cells (MSCs) has been suggested as an effective therapy for chronic liver diseases. The aim of this study was to evaluate the safety, efficacy and therapeutic effects of MSCs in patients with chronic liver disease through a literature-based examination. We performed a systematic review (SR) and meta-analysis (MA) of the literature using the Ovid-MEDLINE, EMBASE and Cochrane Library databases (up to November 2014) to identify clinical studies in which patients with liver diseases were treated with MSC therapy. Of the 568 studies identified by the initial literature search, we analyzed 14 studies and 448 patients based on our selection criteria. None of the studies reported the occurrence of statistically significant adverse events, side effects or complications. The majority of the analyzed studies showed improvements in liver function, ascites and encephalopathy. In particular, an MA showed that MSC therapy improved the total bilirubin level, the serum albumin level and the Model for End-stage Liver Disease (MELD) score after MSC treatment. Based on these results, MSC transplantation is considered to be safe for the treatment of chronic liver disease. However, although MSCs are potential therapeutic agents that may improve liver function, in order to obtain meaningful insights into their clinical efficacy, further robust clinical studies must be conducted to evaluate the clinical outcomes, such as histological improvement, increased survival and reduced liver-related complications, in patients with chronic liver disease.

Degenerative pannus arising from the atlanto-axial articulation is a rare entity, which is associated with chronic atlanto-axial instability in degenerative arthropathies. Due to cervical instability and the mass effect on the spinal cord, it can produce severe neck pain and compressive myelopathy. We report a case of cervical myelopathy resulting from non-rheumatoid atlanto-axial subluxation. The posterior stabilization provided excellent neurological improvement and pannus regression. Early recognition of this condition is important as the clinical condition will deteriorate without surgical interventions.

PURPOSE: It is necessary to develop a proper payment system for more health care facilities to provide hospice and palliative cares. In deciding the proper level of payment for hospice per diem fee, willingness to pay (WTP) may provide one of the critical information. This study was conducted to determine WTP for hospice care and to analyze those factors affecting WTP. MATERIALS AND METHODS: A contingent valuation method with a double-bounded dichotomous-choice model was used. Interview survey was organized and conducted by a survey company from April 4 to 18, 2008. The mean WTP was calculated through an infinite integration of survival functions. RESULTS: The average willingness to pay was found to be 42,240 Korean won (KRW) (USD 35), with the amount becoming higher as hospice services were deemed more necessary or where average monthly household income was higher. The amount was also higher among male respondents than females. CONCLUSION: To compare this WTP with actual cost (32,500 KRW) (USD 27) for hospice care. To facilitate hospice service, hospice specific payment system should be developed. This study provides information regarding the general public's preference of hospice service and their WTP for hospice care, and it may be useful in the decision-making process.

BACKGROUND: The rapid platelet function assay (RPFA) has recently been developed and used to monitor the antiplatelet effects on the P2Y12 ADP receptor. We describe the platelet response to clopidogrel and ticlopidine using the RPFA and identify the clinical factor related to laboratory resistance in patients with ischemic stroke. METHODS: Of the 172 outpatients with ischemic stroke or transient ischemic attack (TIA) enrolled in this study, 86 were taking clopidogrel (75 mg/day) and 86 were taking ticlopidine (500 mg/day). Demographic data, vascular risk factors, stroke subtypes, and the results of blood tests were recorded. Inhibition is described as the percentage change from baseline aggregation, and is calculated from the P2Y12 reaction unit (PRU) and the base PRU on the RPFA. Those patients who displayed ineffective aggregation-inhibition (inhibition <20%) on the RPFA were defined as nonresponders. RESULTS: The response of platelet aggregation-inhibition to clopidogrel and ticlopidine exhibited a variable distribution (PRU; coefficient of variability, 0.477). Ineffective platelet inhibition was detected in 25.6% of the clopidogrel group and 3.5% of the ticlopidine group (p<0.001). In addition to clopidogrel, TIA and diabetes exhibited significantly higher ineffective platelet inhibition in a univariate analysis. In the multivariate analysis, clopidogrel and TIA remained significant, and diabetes fell to borderline significance (p=0.061). CONCLUSIONS: The response to clopidogrel and ticlopidine can vary between patients. Platelet inhibition is lower for clopidogrel than for ticlopidine on the platelet function test in patients with ischemic stroke. The clinical impact of these results remains uncertain; further investigations are needed.

BACKGROUND/AIMS: The prevalence and clinical characteristics of entecavir (ETV) resistance is not well known. The aim of this study was to determine the frequency of genotypic resistance in nonresponders and virologic breakthrough (VBT) patients. METHODS: The medical records of 76 chronic hepatitis B patients treated for a least 6 months from October 2006 to October 2008 were reviewed retrospectively. We divided patients into two groups: nucleoside analogue (NA)-naive patients (n=38) and LAM experienced patients (n=38). NA-naive and LAM experienced patients received ETV at 0.5 and 1.0 mg/day, respectively. The virologic response and VBT were investigated in both groups. We used the multiplex restriction fragment mass polymorphism (RFMP) method to test genotypic resistance at the rtI169, rtT184, rtS202, rtM204, and rtM250 sites. RESULTS: Age, gender, serum ALT, and HBV DNA level before treatment did not differ between the groups. Neither VBT nor nonresponse was observed in the NA-naive group, whereas VBT and nonresponse were observed in three patients each in the lamivudine (LAM)-experienced group; all six patients had YMDD mutation at study enrollment, all three patients with VBT had genotypic resistance to ETV, but the three nonresponse patients did not have genotypic resistance to ETV. CONCLUSIONS: We suspect that VBT is mostly associated with genotypic resistance to ETV. However, nonresponse might be associated with the continuance or reselection of the YMDD mutant in LAM-experienced patients.

PURPOSE: This study was designed to determine the optimum radiotherapy technique for internal mammary node (IMN) irradiation after breast-conserving surgery. MATERIALS AND METHODS: We selected ten cases of early stage partial mastectomy for plan comparison. Five of the patients were treated to the right-side breast and the rest of the patients were treated to the left-side breast. For each case, four different treatment plans were made to irradiate the entire breast, IMNs and supraclavicular lymph nodes (SCLs). The four planning techniques include a standard tangential field (STF), wide tangential field (WTF), partially wide tangential field (PWT) and a photon-electron mixed field (PEM). We prescribed a dose of 50.4 Gy to the SCL field at a 3 cm depth and isocenter of the breast field. RESULTS: The dose distribution showed clear characteristics depending on the technique used. All of the techniques covered the breast tissue well. IMN coverage was also good, except for the STF, which was not intended to cover IMNs. For the cases of the left-side breasts, the volume of the heart that received more than 30 Gy was larger (in order) for the WTF, PWT, PEM and STF. For radiation pneumonitis normal tissue complication probability (NTCP), the PWT showed the best results followed by the STF. CONCLUSION: Despite the variety of patient body shapes, the PWT technique showed the best results for coverage of IMNs and for reducing the lung and heart dose.

PURPOSE: We analyzed the histopathologic findings of the patients with ultrasongraphic Breast Imaging Reporting and Data System (BI-RADS) Category 4a breast lesions to determine which patient can be excluded from any invasive, diagnostic procedure in the future. METHODS: Of the 180 cases of BI-RADS Category 4a breast lesions that were diagnosed with ultrasonography during a 6 month-period, 132 cases were pathologically confirmed and these were analyzed retrospectively. Four benign cases that did not undergo any further procedure after fine needle biopsy and 6 malignant cases (4.5%) were excluded from this study. RESULTS: Of the 122 cases, 77 cases (63.1%) showed homogeneous benign finding, and 45 cases (36.9%) showed heterogeneous finding that was made up of two or more different pathologic lesions. Fibroadenoma (55.8%) was the most frequent pathologic finding in the cases with homogeneous finding, followed by fibrocystic change (14.3%), and fibrosis (7.8%). The cases with heterogeneous finding presented fibrocystic change (55.5%), microcalcification (48.8%), ductal hyperplasia (42.2%), and fibroadenoma (31.1%) in the order of frequency. CONCLUSION: Lesion with heterogeneous histopathologic nature was the most frequent finding defined as category 4a in breast ultrasonography, followed by fibrodenoma, fibrocystic change, microcalcification, and ductal hyperplasia. Refining more specific ultrasonographic findings of these lesions would guarantee that radiologists exclude more benign lesions from category 4a.

BACKGROUND: Topical steroids are a widely used therapeutic agent in dermatology. However, little objective data has been collected in order to assess the awareness, knowledge and behavior of patients regarding the use of topical steroids. OBJECTIVE: The goal of this study was to investigate the current state of awareness, knowledge, and behavior of patients regarding topical steroid use. METHODS: A written questionnaire was distributed to 570 outpatients who visited the dermatologic clinics of the University Hospital. Of these, 504 were appropriate and thus were included in this study for further statistical analysis. The questionnaire consisted of 26 items concerning the overall evaluation of the awareness, and behavior of outpatients regarding their use of topical steroids. RESULTS: The results demonstrated that of 504 patients included in the analysis, 53.8% bought topical steroids with a dermatologist's prescription, whereas 33.6% obtained their topical steroids without prescription. The patient recognition rate of brand name, therapeutic effects, and side effects of topical steroids was 58%, 77% and 26%, respectively. Twenty percent of patients who have used topical steroids complained of side effects, the most common of which being pruritus (7.5% of cases). More than half of the patients said they obtained their information about topical steroids from sources other than the dermatologist. More than three quarters of patients (77%) applied topical steroids 1-2 times per day, whereas the overusers (4%) and the long-term users (16%) were applying topical steroids more than 5 times a day and longer than 16 weeks, respectively. CONCLUSION: The results indicate that topical steroids have been used without sufficient information and guidelines. Taken together, it is suggested that dermatologists should more thoroughly explain the therapeutic effects, indications, and side effects of topical steroids to their patients.
