PURPOSE: Bisphosphonates are widely used for the management steroid-induced osteoporosis (SIO) in children. With the increasing use of bisphosphonates, there have been reports of abnormal radiological findings in the growing skeleton. Therefore, their use in pediatric patients remains controversial. The present study was conducted to evaluate the long-term follow-up radiographic features, particularly metaphyseal sclerotic lines, in children who receive pamidronate therapy for nephropathy. METHODS: Twenty-four children with nephropathy treated with oral calcium and pamidronate (mean duration, 9 months; dose, 100 mg daily), were evaluated retrospectively. All patients had SIO secondary to chronic glucocorticoid therapy for treating nephropathy. Long bone radiographic imaging was performed before treatment with pamidronate, and at follow-up, several years later. Physeal growth rates were estimated by measuring the distance that the sclerotic lines moved on the radiographs during the corresponding time intervals. RESULTS: The mean follow-up period was 138 months. Long bone radiographs showed well-defined sclerotic lines at the metaphyseal ends, progressively moving from the physeal plate to the diaphysis, in all patients. The mean rate of movement of the sclerotic line was 6.21 mm per year. In 12 patients, the lines disappeared. The mean rate of growth in height was 7.33 cm per year. CONCLUSIONS: Results of long-term follow-up suggest that the metaphyseal sclerotic lines associated with pamidronate treatment tend to disappear without affecting overall skeletal growth. Bisphosphonate treatment for SIO in children with nephropathy seems to be safe, although further studies in larger number of patients are needed.

Microalbuminuria is a marker of generalized endothelial dysfunction resulting from arterial stiffness or insulin resistance, and brachial-ankle pulse wave velocity (baPWV) is a good measure of arterial stiffness. We aimed to investigate whether elevated baPWV is independently associated with microalbuminuria. This study included 1,648 individuals aged over 40 who participated in the baseline Multi-Rural Cohort Study conducted in Korean rural communities between 2005 and 2006. Participants were classified into less than 30 mg/g as normoalbuminuria or 30-300 mg/g as microalbuminuriausing urinary albumin creatinine ratio (UACR). The median and Q1-Q3 baPWV values were significantly higher in the microalbuminuric group both in men (1,538, 1,370-1,777 cm/s vs. 1,776, 1,552-2,027 cm/s, P < 0.001) and women (1,461, 1,271-1,687 cm/s vs. 1,645, 1,473-1,915 cm/s, P < 0.001). BaPWV was independently associated with microalbuminuria in both genders after adjusting for pulse rate; fasting blood glucose; triglyceride; homeostatic model assessment insulin resistance (HOMA(IR)) and, history of hypertension and diabetes. Fasting blood sugar and HOMA(IR) were judged as having nothing to do with multicolinearity (r = 0.532, P < 0.001). Elevated baPWV was independently associated with microalbuminuria regardless of insulin resistance among rural subjects over 40 yr.

PURPOSE: This study tries to identify experience of verbal abuse, emotional response, and ways to deal with verbal abuse against nurses in hospitals. METHODS: This study was a descriptive research and conducted from April to July 2011. One hundred and seventeen nurses with over one-year experience in general wards were selected and evaluated. The data were analyzed using descriptive analysis, independent t-tests, and one-way ANOVA. RESULTS: The nurses' experience rate of verbal abuse during the entire period of work in hospitals was 98.3%. The majority of the nurses were verbally abused by patients (70.9%), followed by patients' relatives (65.8%), physicians (61.5%), and coworkers (58.1%). Overall negative emotional response score of nurses after verbal abuse was 38.82+/-8.28. Ways to deal with verbal abuse were as follows: suppression was 74.4%, complaining of an injustice to close people, 67.5%, and ignoring, 43.6%. CONCLUSION: Nurses have significantly been exposed to verbal abuse while working in hospitals. Therefore, hospital managers and nurse managers are required to inform other staff and visitors in hospitals the real condition of verbal abuse against nurses and provide a safe work environment by developing the report and disposal system of verbal abuse.

Fibrolamellar carcinoma (FLC) is a rare variant of hepatocellular carcinoma (HCC). A 26-year-old female presented a hepatic mass and mild elevation of liver enzymes. Viral markers were negative, and levels of tumor markers were normal. Radiologically, the mass was well demarcated with central dot-like calcification and hypervascularity. Under the diagnosis of hepatocellular carcinoma, right lobectomy was performed. The tumor was grayish yellow with central fibrosis and focal hemorrhage and invaded a septal bile duct. Non-neoplastic liver was unremarkable. Microscopically, the tumor consisted of large polygonal cells in sheets, cords, and pseudoglands that were interwound by dense collagenous stroma. Tumor cells had abundant deeply eosinophilic cytoplasm and large nuclei with prominent nucleoli. Intracellular bile pigments and pale bodies were present. Tumor cells were diffusely immunostained for cytokeratin 7 (CK7), but not for cytokeratin 20 (CK20). Strong expression of CK7 in the present case suggests dual differentiation of FLC.

Rice body formation in a joint or bursa is a rare condition, and is usually associated with rheumatoid arthritis or tuberculous arthritis. Here we describe a case of multiple rice body formation in a shoulder joint and in adjacent bursae, which was confirmed to be due to septic arthritis by Candida species. To the best of our knowledge, rice body formation in Candida septic arthritis in an immune-competent patient has not been previously reported.

BACKGROUNDS/AIMS: Pancreaticoduodenctomy (PD) is associated with high rates of postoperative morbidity and mortality. Although many studies have shown that early postoperative enteral nutrition improves postoperative outcomes, limited clinical information is available on postoperative early oral feeding (EOF) after PD. The aim of this study was to evaluate the clinical feasibility, safety, and nutritional effects of EOF after PD. METHODS: Clinical outcomes were investigated in 131 patients who underwent PD between 2003 and 2013, including 81 whose oral feeding was commenced within 48 hours (EOF group) and 50 whose oral feeding was commenced after resumption of bowel movements (traditional oral feeding [TOF] group). Postoperative complications, energy intake, and length of stay (LOS) were reviewed. RESULTS: Demographic factors were similar in the two groups. The EOF group had a significantly shorter LOS (25.9+/-8.5 days vs. 32.3+/-16.3 days; p=0.01) than the TOF group. The rates of anastomotic leak (1.2% vs. 16%, p=0.00) and reoperation (3.7% vs. 20%, p=0.01) were significantly lower in the EOF group. In the clinically acute phase from postoperative day 1 to day 5, the mean daily calorie intake (847.0 kcal vs. 745.6 kcal; p=0.04) and mean daily protein intake (42.2 g vs. 31.9 g; p=0.00) in the EOF group were significantly higher than that in the TOF group. CONCLUSIONS: Postoperative EOF is a clinically safe, feasible, and effective method of nutritional support after PD.

PURPOSE: The purpose of this study was to evaluate the cleansing effect of recently developed alkaline ionized water, e-WASH, on microorganisms of the denture surface. MATERIALS AND METHODS: Removable partial and complete dentures were randomly assigned to the experimental group of 41 dentures, and the control group of 26. The denture was immersed in the e-WASH solution (experimental group), or tap water (control group) for 5 minutes. The plaque was collected from the denture surface before and after immersion, and smeared on the slide glass. Amount and motility of microorganisms were compared according to the morphology and strain of microorganisms, using the phase contrast microscope. Statistical analysis was accomplished with paired t-test and independent t-test at 95% confidence level (P<.05). RESULTS: 1. The amount of cocci, bacilli, filamentous, spiral/comma, and the motility of bacilli, filamentous, and spiral/comma were decreased after denture cleansing with the alkaline ionized water, e-WASH (P<.05). But in the control group, only the amount of cocci showed a significant difference (P<.05), but no difference from the others. There were no differences in other analysis. 2. In the experimental group, the amount of cocci, bacilli, filamentous, spiral/comma, and the motility of bacilli, filamentous, and spiral/comma were smaller and more inactive compared to the control group (P<.05). CONCLUSION: These results indicated that the alkaline ionized water, e-WASH could effectively reduce the amount and motility of the experimented microorganisms on the denture surface, and that e-WASH could be recommended as an effective denture cleanser.

Phosphodiesterase (PDE) 4 inhibitors have been shown to induce the cAMP-mediated signaling pathway by inhibiting cAMP hydrolysis. This study investigated the effect of a PDE4 inhibitor on the expression of the inducible cAMP early repressor (ICER), which is an endogenous inhibitor of CRE- mediated transcription, in osteoblastic cells. RT-PCR analysis revealed that rolipram, a PDE4 inhibitor, stimulates the ICER mRNA in a dose dependent manner. The induction of ICER mRNA expression by rolipram was suppressed by the inhibitors of protein kinase A (PKA) and p38 MAPK, suggesting the involvement of PKA and p38 MAPK activation in ICER expression by rolipram. It was previously shown that rolipram induced the expression of TNF-related activation-induced cytokine (TRANCE, also known as RANKL, ODF, or OPGL) in osteoblasts. This paper provides evidences that a transcriptional repressor like ICER might modulate TRANCE mRNA expression by rolipram in osteoblasts.

OBJECTIVE: The aim of this study was to determine the optimal loading conditions for pure intrusion of the six maxillary anterior teeth with miniscrews according to alveolar bone loss. METHODS: A three-dimensional finite element model was created for a segment of the six anterior teeth, and the positions of the miniscrews and hooks were varied after setting the alveolar bone loss to 0, 2, or 4 mm. Under 100 g of intrusive force, initial displacement of the individual teeth in three directions and the degree of labial tilting were measured. RESULTS: The degree of labial tilting increased with reduced alveolar bone height under the same load. When a miniscrew was inserted between the two central incisors, the amounts of medial-lateral and anterior-posterior displacement of the central incisor were significantly greater than in the other conditions. When the miniscrews were inserted distally to the canines and an intrusion force was applied distal to the lateral incisors, the degree of labial tilting and the amounts of displacement of the six anterior teeth were the lowest, and the maximum von Mises stress was distributed evenly across all the teeth, regardless of the bone loss. CONCLUSIONS: Initial tooth displacement similar to pure intrusion of the six maxillary anterior teeth was induced when miniscrews were inserted distal to the maxillary canines and an intrusion force was applied distal to the lateral incisors. In this condition, the maximum von Mises stresses were relatively evenly distributed across all the teeth, regardless of the bone loss.

This study compared the microtensile bond strength (microTBS) and microscopic change of two 2-step and two 1-step self-etching adhesives to dentin according to storage times in distilled water. Occlusal dentin was exposed in 48 human molars. They were divided to four groups by different adhesives: SE Bond group (Clearfil SE Bond), AdheSE group (AdheSE), Adper group (Adper Prompt L-Pop), and Xeno group (Xeno III). Each group was stored in 37degrees C distilled water for 1, 15, and 30 days. Resin-bonded specimens were sectioned into beams and subjected to microTBS testing with a crosshead speed of 1 mm/minute. For SEM observation, one specimen was selected and sectioned in each group after each stroage time. Resin-dentin interface was observed under FE-SEM. In all storage times, mean microTBS of SE group was significantly higher than those of other groups (p < 0.05). There was no significant difference between mean microTBS of SE group and AdheSE group among all storage times, but significant difference between 1- and 30-day storage in mean microTBS of Adper group and Xeno group (p < 0.05). For 1-and 15-day storage, all groups showed the close adaptation between resindentin interfaces. For 30-day storage, resin-dentin interfaces showed wide gap in Adper group and separate pattern in Xeno III group.
