Teriparatide (TPTD) is a bone-forming agent used to treat postmenopausal osteoporosis. Since hip fractures are related to higher morbidity and mortality rates than other fractures, efficacious osteoporosis drugs for the hip are critical. We reviewed research articles reporting the efficacy of TPTD in terms of bone mineral density (BMD), fractures prevention, changes in the outer diameter, cortical thickness and porosity, post-operative periprosthetic BMD loss, and healing of typical and atypical fractures of the hip. Data meta-analyses indicated that TPTD not only increased the BMD of the proximal femur but also decreased the risk of hip fractures. Even though TPTD increases the cortical bone porosity of the proximal femur, the bone strength does not decrease as the majority of the porosity is located at the endocortex; further, it increases the outer diameter and thickens the cortical bone.TPTD stimulates bone remodeling and facilitates callus maturity and fracture healing. There have been many reports on improving the effect of TPTD on the healing of atypical fractures; therefore it is advisable to use TPTD considering the increase benefit compared to the risk.

BACKGROUND: Regular blood donation can lead to iron deficiency. Serum ferritin is sensitive indicator of body iron depletion. The aim of this study is to evaluate serum ferritin reagents using the turbidimetric immunoassay (TIA) and to establish a reference range in first time blood donors in Korea. METHODS: The study was prospectively conducted, between Feb. 2011 and Apr. 2011, on 120 male and 120 female blood donors at five blood centers. Serum ferritin was determined by TIA using two brands of reagents (Beckman Coulter Inc., USA; HBi, South Korea) and two automated chemistry analyzers (AU640, Beckman Coulter Inc.; Hitachi7180, Hitachi High-Technologies Corp., Japan). Precision, linearity, limit of detection, analytical measurement range and correlation with chemiluminescent immunoassay (CLIA) were evaluated. A reference range for serum ferritin in first time donors was established. RESULTS: The coefficients of variation of precision were less than 4%. Linearity was observed up to 312.7~450 microg/L depending on which reagent used. Both reagents had good correlation with CLIA results. Serum ferritin levels for first time donors showed left skewed distribution. The reference ranges for males and females were 34.1~385.9 microg/L and 6.8~121 microg/L using Beckman Coulter (AU) reagent, and 18.7~271.3 microg/L and 4~83.7 microg/L using HBi (AU) reagent, and 15.2~274.7 microg/L and 6~84 microg/L using HBi (Hitachi) reagent. CONCLUSION: A reference range for serum ferritin in first time donors in Korea was established using automated chemistry analyzers with inexpensive TIA reagents.

BACKGROUND: Evidence-based clinical practice guidelines (CPGs) are defined as “statements that are scientifically reviewed about evidence and systematically developed to assist in the doctors' and patients' decision making in certain clinical situations.” This recommendation aims to promote good clinical practice for the provision of safe and effective practices of conscious sedation in dentistry. METHODS: The development of this clinical practice guideline was conducted by performing a systematic search of the literature for evidence-based CPGs. Existing guidelines, relevant systematic reviews, policy documents, legislation, or other recommendations were reviewed and appraised. To supplement this information, key questions were formulated by the Guideline Development Group and used as the basis for designing systematic literature search strategies to identify literature that may address these questions. Guideline documents were evaluated through a review of domestic and international databases for the development of a renewing of existing conscious sedation guidelines for dentistry. Clinical practice guidelines were critically appraised for their methodologies using Appraisal of guidelines for research and evaluation (AGREE) II. RESULTS: A total of 12 existing CPGs were included and 13 recommendations were made in a range of general, adult, and pediatric areas. CONCLUSION: The clinical practice guidelines for conscious sedation will be reviewed in 5 years' time for further updates to reflect significant changes in the field.

This study was conducted to evaluate the influence of the C-factor on the bond strength of a 6th generation self-etching system by measuring the microtensile bond strength of four types of restorations classified by different C-factors with an identical depth of dentin. Eighty human molars were divided into four experimental groups, each of which had a C-factor of 0.25, 2, 3 or 4. Each group was then further divided into four subgroups based on the adhesive and composite resin used. The adhesives used for this study were AQ Bond Plus (Sun Medical, Japan) and Xeno III (DENTSPLY, Germany). And composite resins used were Fantasista (Sun Medical, Japan) and Ceram-X mono (DENTSPLY, Germany). The results were then analyzed using one-way ANOVA, a Tukey's test, and a Pearson's correlation test and were as follows. 1. There was no significant difference among C-factor groups with the exception of groups of Xeno III and Ceram-X mono (p < 0.05). 2. There was no significant difference between any of the adhesives and composite resins in groups with C-factor 0.25, 2 and 4. 3. There was no correlation between the change in C-factor and microtensile bond strength in the Fantasista groups. It was concluded that the C-factor of cavities does not have a significant effect on the microtensile bond strength of the restorations when cavities of the same depth of dentin are restored using composite resin in conjunction with the 6th generation self-etching system.

BACKGROUND: The definition of evidence-based clinical practice guidelines (CPGs) is "statements that are systematically developed to assist in the doctors' and patients' decision-making in certain situations." This study aims to establish the concept of evidence-based CPGs and investigate the development status to seek measures to apply evidence-based methods to CPG development for dental sedation in Korea. METHODS: The study conducted systematic searching methods based on evidence-based CPGs. Articles published between 1995 to 2015 were searched on a Korean database and the international database PubMed. The search was based on keywords related to four subjects (dentistry, clinical practice, guideline, recommendation). Two authors independently reviewed the searched articles to determine their analysis inclusion and the convergence stages, and to arrive at a conclusion through discussion. RESULTS: A total of 65 Korean CPGs were included. There were 51 medical guidelines, of which seven were dental and seven were Oriental medicine. CONCLUSIONS: As a basic direction for the development of evidence-based CPGs, this work suggests the following: increased awareness; consensus on the need to supply evidence-based development methods; education, computerization, and systematic observation of evidence-based CPG development methods; continuous research development and distribution of CPGs; and creation of a database for Korean clinical dentistry practice outcomes.

Liposarcomas are one of the most common soft-tissue sarcomas in adults. They usually arise in the deep soft tissues, and patients present with large painless masses. Four major types of liposarcomas are generally recognized and have epidemiologic and prognostic differences: atypical lipomatous neoplasm/well-differentiated; myxoid/round- cell; dedifferentiated; pleomorphic variants. Myxoid liposarcoma is the second most common type of liposarcoma, representing 30~40% of all liposarcomas in the extremities. We report a case of myxoid liposarcoma in a 78-year-old man who presented with an asymptomatic, firm, deep-seated mass in the lateral aspect of his left upper arm.

PURPOSE: The purpose of this study is to evaluate the clinical effectiveness of a rehabilitation program for the patients with lateral epicondylitis. MATERIALS AND METHODS: Twenty-three patients with lateral epicondylitis were included from April 2009 to October 2009 and all the patients were treated with a rehabilitation program for 6 weeks. The evaluation at baseline and at 12 weeks after rehabilitation included the subjective assessment of symptoms and the objective assessment with measuring the grip strength and muscle power of the wrist extensors and flexors and the forearm supinators and pronators. After 6 months, subjective satisfaction was evaluated via telephone calls. The data was analyzed using the Wilcoxon signed rank test (SPSS ver. 16.0). RESULTS: At 12 weeks, the subjective satisfaction was improved in on the three questionnaires. The grip strength increased from 25.1 kg to 37.8 kg (p<0.05). On the Biodex analysis, there was significant difference at the wrist extensors. At 6 months, 21 cases had excellent or good results according to the score and 2 cases complained of remaining pain. CONCLUSION: Our rehabilitation program is thought to be good treatment for the patients with lateral epicondylitis, and it is a practical and precautionary step for the cases of lateral epicondylitis if the patients themselves are educated to volutarily participate in the program.

BACKGROUND: Peripheral nerve injury may generate pain hypersensitivity, characterized by enhanced nociceptive responses to noxious stimuli and decreased thresholds to innocuous stimuli, and may lead to a chronic neuropathic pain state resulting from an increase in central neuron excitability. This central sensitization is mediated via N-methyl-D-aspartic acid (NMDA) receptor and may involve the production of nitric oxide (NO). In this work, we investigated whether the action of NO and local nitric oxide synthase (NOS) expression play a role in neuropathic pain in a rat model. METHODS: Neuropathic pain was produced by resecting two branches of the sciatic nerve. N-nitro-L-arginine methyl ester (L-NAME) (a nonselective NOS inhibitor), or 7-nitroindazole (7-NI) (a neuronal NOS (nNOS) inhibitor), or aminoguanidine (AG) (an inducible NOS (iNOS) inhibitor) were administered locally for 2, 7, or 14 days via osmotic pumps. Behavioral tests for pain were conducted after nerve injury using mechanical and thermal stimuli applied to the hind paws. We used immunohistochemical methods to provide evidence for endothelial NOS (eNOS), nNOS, and iNOS expression. RESULTS: Following nerve injury, significant mechanical allodynia and thermal hyperalgesia were observed in rats treated with AG or 7-NI. In contrast, when L-NAME, a known potent inhibitor of eNOS was applied locally, no significant mechanical allodynia or thermal hyperalgesia was observed. No dependency on the route or duration of NOS inhibitor administration was noted. Increased immunoreactivities of the eNOS and nNOS isoforms were intense and discrete at 48 hour following nerve injury, unlike sham exposed intact nerves. In 14 day stumps, iNOS staining was observed in the endoneurium and perineurium. eNOS immunoreactivity at 2 days after nerve injury was not observed in L-NAME treated rats. At 14 days after nerve injury, iNOS immunoreactivity was rarely observed in AG and L-NAME treated rats. CONCLUSIONS: Our results indicate that an early eNOS expression plays a critical role in the development of neuropathic pain.
