Evaluating the association between gingival crevicular blood glucose levels and finger capillary blood glucose levels according to periodontal status

OBJECTIVES

The aim of this study was to evaluate the association between gingival crevicular blood glucose levels (GCBG) and finger capillary blood glucose levels (FCBG) according to the periodontal status of patients.

MATERIALS AND METHODS

In this case-control study, 80 patients were divided into 4 groups according to their periodontal status. In these patients, an area of the maxillary gingiva with the highest probing depth was selected for blood sampling. Blood glucose obtained from this area and the right fingertip was measured with a glucometer. Data were analyzed using ANOVA and Pearson correlation coefficient with a significance threshold of 0.05.

RESULTS

The groups studied were matched in regard to their sex and age (P > 0.05). The average FCBG and GCBG were not significantly different according to periodontal status (P > 0.05). The correlation between the FCBG and the GCBG showed a significant positive correlation in the total number of participants (P < 0.05, r = 0.531).

CONCLUSION

The study observed a positive association between GCBG and FCBG. However, the relationship with periodontal status appeared to be relatively weak. Further research may be needed to determine the potential efficacy of GCBG in diabetes screening during periodontal examinations.

CLINICAL RELEVANCE

Most patients with diabetes do not have proper periodontal health, so it may be helpful to screen for diabetes during periodontal examinations.

Ecology of malaria vector Anopheles culicifacies in a malarious area of Sistan va Baluchestan province, south-east Islamic Republic of Iran

A study was done of the bionomics, insecticide susceptibility and irritability status of Anopheles culicifacies in Sistan va Baluchestan province. Sampling was performed to determine the following parameters: species identification, seasonal activity, adult and larval susceptibility tests, irritability tests, anthropophily index and sporozoite rate. An. culicfacies adults were susceptible to all tested pyrethroid insecticides. An. culicfacies started to appear indoors in late May, showing 2 peaks in June and September. Fenitrothion, cyfluthrin and permethrin had the least irritancy effect and DDT the highest. Only 2/860 females tested were infected with Plasmodium spp. (sporozoite rate: 0.25%). ELISA testing of 250 blood meals derived from night-biting collections of female mosquitoes from humans and cows revealed that only 12.5% were human-fed.

Residual Effects of Deltamethrin WG 25% as a New Formulation on Different Surfaces against Anopheles stephensi, in Southeastern Iran

BACKGROUND

Indoor residual spraying (IRS) is functioned as national interventions against malaria in southeastern foci of Iran and deltamethrin WP one of the insecticides have been used since past decade. In this study, the residual activity of the wettable granule (WG) was studied on different surfaces in hut scale trial against Anopheles stephensi in Iranshahr District, southeastern Iran.

METHODS

Three dosages of 25, 40 and 50 mg a.i./m(2) of deltamethrin WG 25% formulation were applied on plaster, cement, mud, and wooden surfaces using Hudson(®) X-pert compression sprayer having 10 litters capacity.

RESULTS

The residual effects of deltamethrin WG 25% on different surfaces was assessed based on reduction of mortality An. stepehnsi from 100% to about 70%. At 25, 40 and 50 mg a.i./m(2) the WG formulation of deltamethrin had a bioefficacy for about 2, 3 and 4 months respectively.

CONCLUSION

There was an expectable fluctuation in mortality of An. stephensi at different sprayed surfaces as well as dosages. The proposed 50 mg/m2 WG is the longest activity for up to 4 months which needs to be applied for two spraying cycles per year at the climatically condition of southwestern Iran.
