Effect of Different Preparations of Fluoride Gel on Salivary pH of Albino Rats

Abstract Objective: To evaluate the effect of different preparations of fluoride gels on the salivary pH of albino rats. Material and Methods: This experimental study consisted of 40 Albino rats randomly divided into four equal groups. Group A was the control group and received no intervention. Experimental group B received a topical application of 0.2% sodium fluoride gel. Experimental group C received topical application of stannous fluoride gel 0.4%. Experimental group D received topical application of APF gel (1.23% acidulated phosphate fluoride gel). The different preparations of the gels were applied once daily for 4 minutes on the occlusal surface of the right maxillary molars for 14 days. Salivary pH values were recorded immediately after the application of gels with the help of pH paper on day 1 and day 14. Results: There was a significant difference in the pH level of groups B, C and D after 14 days of fluoride application (p < 0.05). The non-parametric Kruskal Wallis test was applied for the comparison between the groups. Conclusion: This study concluded that all the fluoride gels after administration caused the acidic pH of saliva with the most acidic effect produced by APF gel (AU).

Provincial differences in levels, trends, and determinants of childhood immunization in Pakistan

Background: Efforts to improve immunization rates are urgently needed in Pakistan but national statistics mask important local differences in immunization levels and determinants.

Aim: In this study we aimed to determine how similar or different are recent trends and levels of immunization coverage in Pakistan's 4 main provinces [Punjab, Sindh, Khyber Pakhtunkhwa [KPK] and Balochistan], and what factors are associated with complete childhood immunization in each province.

Method: We analysed data from the 2006–07 and 2012–13 Pakistan Demographic and Health Surveys. Trends in immunization coverage among children aged 12–23 months were calculated for each province. Bivariate and multivariate analyses were conducted to identify factors associated with complete immunization.

Results: The proportion of children completely immunized had risen significantly in Punjab but had fallen significantly in Balochistan. Complete coverage ranged from 16.4% in Balochistan to 65.8% in Punjab [2012–13]. Tetanus toxoid injection during pregnancy was a significant predictor of complete immunization everywhere. Other predictors in specific provinces were: urban residence in Balochistan, wealth in Sindh and KPK, mother's education in Punjab and KPK, and distance to the facility in Punjab.

Conclusions: Although some strategies to increase immunization coverage are relevant nationwide, programme managers need to seek solutions specific to provincial trends and predictors. This analysis demonstrates that viewing childhood immunization in Pakistan through a provincial lens can help achieve a deeper understanding of the challenges and potential strategies to boost coverage

Efficacy of brow suspension with autogenousfascia lata in simple congenital ptosis

Objective: To assess the mean change in interpalpebral fissure height and marginal reflex distance after brow suspension with autogenous fascia lata sling in patients of ptosis

Methods: This was a Quasi experimental study conducted at Department of Ophthalmology, Mayo Hospital, King Edwards Medical University Lahore, from Jan 2013 to June 2016. Included were the patients who had unilateral or bilateral ptosis with poor levator function [< 5 mm]. Informed consent was obtained from all patients after explaining about the research project. Patients were admitted in ward and all of them underwent surgery by a single surgical team. The surgical procedure was performed in supine position under general anesthesia in children and uncooperative patients. Patients were followed at week 4, 8, 12 and 24 to observe vertical interpalpebral fissure height and marginal reflex distance

Results: The mean age of the patients was 9.03 +/- 5.26 years. The mean Inter palpebral fissure height [IPFH] was 4.40+/-0.91 mm and mean MRD was 0.50 +/- 1.00 mm before surgery while after surgery it was 7.41+/-0.76 mm and 3.10 +/- 1.50 mm respectively at 04 weeks. The mean IPFH and MRD at 24 weeks postoperatively were 8.43+/-0.98 mm and 3.60 + 1.50 mm respectively. The mean change in IPFH and MRD at 24th week, were 3.90 +/- 0.34 mm and 3.50 +/- 1.00 mm

Conclusion: Brow suspension with fascia lata sling is safe and effective technique for correction of ptosis with poor levator function
