Abstract Inflammatory and replacement tooth resorption are common outcomes following tooth replantation, biological mediators involved in these processes are widely unknown. The aim study was to investigate molecules involved in tooth resorption following permanent tooth avulsion and delayed replantation. Dog premolars were extracted and kept dry for 20, 60 and 90 minutes (n= 30). The teeth were replanted, splinted. After 120 days, the animals were euthanized and tissues were removed for histological processing. Slides were stained for microscopic analysis, submitted to tartrate resistant acid phosphatase (TRAP) histoenzymology and immunostained for RANK, RANKL, OPG, alkaline phosphatase and periostin. Data obtained were submitted to statistical analysis using the chi-square, Fisher and one-way ANOVA tests (alpha= 0.05). In inflammatory resorption areas, TRAP + and RANK + osteoclasts surrounding the replanted teeth were identified, regardless of the extra-alveolar time. RANKL synthesis in this region was higher in longer extra-alveolar times and was more intense after keeping the tooth dry for 90 minutes compared to other periods. In the replacement reabsorption area, there was lower synthesis of periostin and higher alkaline phosphatase production. Inflammatory resorption was characterized by osteoclast recruitment and RANKL synthesis and replacement resorption was characterized by inhibition of periostin and alkaline phosphatase syntheses.

Serum levels of bone-origin alkaline phosphatase and of tartrate-resistant acid phosphatase were measured in Caucasian women aged 41–69 years who had volunteered for bone densitometry. Bone alkaline phosphatase and tartrate-resistant acid phosphatase were inversely correlated with vertebral bone density and with femoral neck bone density. Bone alkaline phosphatase and acid phosphatase were also significantly correlated, consistent with the concept of ‘coupling’ between osteoblast and osteoclast activity.

Background: Shivering is an undesirable complication following general anesthesia and spinal anesthesia, whose early control can reduce postoperative metabolic and respiratory complications. Therefore, this study aims to compare the effects of prophylactic injection of ketamine and pethidine on postoperative shivering. Methods: This double-blind clinical trial was performed on 105 patients with short-term orthopedic and ENT surgery. The patients were randomly divided into three groups; 20 minutes before the end of the surgery, 0.4 mg/kg of pethidine was injected to the first group, 0.5 mg/kg of ketamine was injected to the second group, and normal saline was injected to the third group. After the surgery, the tympanic membrane temperature was measured at 0, 10, 20, and 30 minutes. The shivering was also measured by a four-point grading from zero (no shivering) to four (severe shivering). Data were analyzed by one-way ANOVA, Kruskal Wallis, Chi-square and Pearson correlation. Results: The mean age of patients was 35.8+/-11.45 years in the ketamine group, 34.8+/-11.64 years in the normal saline group, and 33.11+/-10.5 years in the pethidine group. The one-way ANOVA showed no significant difference in the mean age between the three groups (P=0.645). The incidence and intensity of shivering were significantly higher in the normal saline group than in the ketamine and pethidine groups (p=0.001). However, there was no significant difference in the incidence and the intensity of shivering between the ketamine and the pethidine groups (p=0.936). Conclusion: The results showed that the 0.5 mg/kg of ketamine could control the post-anesthetic shivering.

Objective: To compare the efficacy of Vestibular sedative versus Epley manoeuvre in the management of benign paroxysmalpositional vertigo. Study design: Interventional Quasi experimental study. Place and duration of study: This study was conducted in ENTOPD Combined Military Hospital Rawalpindi from 1st January 2008 till 30th June 2008. Results: In this study out of 30 cases managed byvestibular sedative, 10 cases showed complete relief of symptoms after 01 month. Out of 30 cases managed by Epley manoeuvre, 28 casesshowed complete recovery after 01 month. The results were compared by Chi square test, as the data was mainly qualitative in nature. Theresults of both the groups were compared on day 3, day 7 and day 30, which revealed that Epley manoeuvre, is more effective than vestibularsedative in treatment of BPPV. Conclusions: Epley manoeuvre is more effective than vestibular sedative for treating the patients of benignparoxysmal positional vertigo.

<p>The purpose of this study is to assess the awareness level and potential challenges for Building Information Modelling (BIM) adoption among the Mechanical, Electrical and Plumbing (MEP) design consultants and contractors in Nigeria, and to get the perspective of BIM in the industry. The research method used in this study was a fieldwork survey using structured questionnaires. The results from the responses were analysed using descriptive statistics, one-way ANOVA test for statistical significant difference, Chi-Square test, and Cross Tab analysis. The findings from the survey show that Nigeria MEP firms have a relatively high level of awareness toward BIM technology. The Most important challenges identified as barriers for BIM adoption are lack of technical expertise on BIM tools utilisation, lack of awareness of BIM technology, and high investment cost in training staff, process change, and software/hardware upgrade.</p>

Abstract Background: Premature menopause may impair the quality of life and expose women to disorders such as cardiovascular disease, osteoporosis, and depression. This study aimed to evaluate the effectiveness of mindfulness on the quality of life of women with premature menopause. Methods: This was a quasi-experimental study in which 62 women were recruited and randomly allocated in two groups of mindfulness and control. The mindfulness group received eight sessions of training. A demographic questionnaire, Menopause-Specific Quality of Life (MENQOL) and a checklist (for assessing frequency and intensity of hot flashes) were used to collect data. The quality of life, frequency, and intensity of hot flashes measured at baseline, after eight weeks and in three months follow-up. The Independent t-test, the chi-square test, and the repeated measure test were used for analyzing data. Results: The score of quality of life was significantly improved after the intervention and in three months follow-up in the mindfulness group compared to the control group (p<0.001). The scores of vasomotor, psychological, physical, and sexual domains also improved significantly in the mindfulness group compared to the control group. The severity and the frequency of hot flashes were significantly reduced in the mindfulness group in comparison to the control group. Conclusion: The results of this study showed that eight weeks of mindfulness training could significantly improve the quality of life and also could reduce the frequency and intensity of hot flashes in women with premature menopause. Using mindfulness for women with premature menopause is recommended.
