Birth preparedness and complication readiness among women attending Immuno-Prophylaxis Centre, Dr. S. C. Government Medical College, Nanded

Background: As signatory to United Nation’s Sustainable Development Goals, India is striving hard to achieve these goals by end of 2030, especially for goal number 3 with targets related to maternal and child health. Birth-preparedness and complication-readiness (BPCR) is a tool to promote maternal and neonatal survival. This study was conducted to assess the perception and practices of recently delivered women on BPCR with its correlates.Methods: Hospital-based cross-sectional study was conducted at Immuno-prophylaxis centre of Dr. Shankarrao Chavan Government Medical College, Nanded, Maharashtra. Women attending IPC along with their baby within two to four months of delivery for immunization of their babies during the month of March 2014 constituted study subject of this study. After obtaining informed consent, data was obtained on socio-demographic characters like age, caste, religion, education, parity, ANC registration and questions regarding birth preparedness and complications readiness in their last pregnancy.Results: Total 117 women found to be eligible as study subject. Overall BPCR index of the study population was 67.28. Proportion of women who received first antenatal check-up within first trimester, four or more antenatal checkups, saved money for childbirth and had institutional delivery were 87.18%, 86.32%, 51.28% and 100% respectively. Around 23.08% women had knowledge of at least 3 key danger signs of pregnancy while only 19.65% identified blood donor. Awareness regarding danger signs of pregnancy and arrangement for blood donor was found poor in comparison to other indicators in study subject.Conclusion: There is need of increasing awareness regarding BPCR so that perception and practices in the community increased.

Reorientation simplified: A device for recording and reproducing the path of insertion for removable partial dentures.

Aim: The record of path of insertion on the dental cast is part of the dentist's work authorization to the dental laboratory technician. The path of insertion record enables the dental technician to replace the cast on a surveyor in the same position that the dentist selected. Analysis of factors that influence the path of insertion should determine a path of insertion that will reduce the potential for dislodgement and promote stability of removable partial denture (RPD). Materials and Methods: The recording of the relation of a cast to a dental surveyor and the transfer of this relationship to the dental laboratory may be done by tripodization, by scoring the base of the cast, or by cementing a reference pin on the cast. Conclusion: Recording the established path of insertion can be difficult when the procedure uses a cemented pin and the casts are mounted in an articulator. This article describes a procedure for innovative dowel pin and sleeve device to record the path of insertion of RPDs, which serves the same purpose as the cemented pin but can be easily removed and replaced.

In vitro comparative evaluation of the effect of two different fiber reinforcements on the fracture toughness of provisional restorative resins.

Background: Fracture of provisional fixed partial denture (FPD) may jeopardize the success of provisional prosthodontic treatment phase and cause patient discomfort. Aim: The aim of this study was to compare the fracture toughness of the Polymethyl Methacrylate (PMMA) resin and Bis-Acryl Composite (BAC) resin reinforced with the Polyethylene and Glass fibers. Materials and Methods: Three groups (N=10) of each of the two materials were prepared for the fracture toughness test. Two groups had the different reinforcements and group without reinforcement served as the control. The mean fracture toughness (MPa.m½ ) was compared by One-way ANOVA, followed by the Scheffe analysis. Fracture toughness between fiber-reinforced PMMA and BAC resin was compared by the independent samples t test. Results: For the controls, the fracture toughness for PMMA resin (0.91) was significantly lower than for the BAC resin (1.19). Glass fiber reinforcement produced significantly higher fracture toughness for both, PMMA (1.48) and BAC (1.82) resin, but the Polyethylene fibers did not (0.95 for PMMA and 1.23 for BAC resin). Among the reinforced groups, Silane impregnated Glass fibers showed highest fracture toughness for the BAC resin (1.82). Conclusion: Of two fiber reinforcement methods evaluated, Glass fiber reinforcement for the PMMA and BAC resin produced highest fracture toughness. Clinical Implications: On the basis of this in--vitro study, the use of Glass and Polyethylene fibers tested may be an effective way to reinforce resins used to fabricate fixed provisional restorations.

The effect of different fiber reinforcements on flexural strength of provisional restorative resins: an in-vitro study

PURPOSE: The aim of this study was to compare the flexural strength of polymethyl methacrylate (PMMA) and bis-acryl composite resin reinforced with polyethylene and glass fibers. MATERIALS AND METHODS: Three groups of rectangular test specimens (n = 15) of each of the two resin/fiber reinforcement were prepared for flexural strength test and unreinforced group served as the control. Specimens were loaded in a universal testing machine until fracture. The mean flexural strengths (MPa) was compared by one way ANOVA test, followed by Scheffe analysis, using a significance level of 0.05. Flexural strength between fiber-reinforced resin groups were compared by independent samples t-test. RESULTS: For control groups, the flexural strength for PMMA (215.53 MPa) was significantly lower than for bis-acryl composite resin (240.09 MPa). Glass fiber reinforcement produced significantly higher flexural strength for both PMMA (267.01 MPa) and bis-acryl composite resin (305.65 MPa), but the polyethylene fibers showed no significant difference (PMMA resin-218.55 MPa and bis-acryl composite resin-241.66 MPa). Among the reinforced groups, silane impregnated glass fibers showed highest flexural strength for bis-acryl composite resin (305.65 MPa). CONCLUSION: Of two fiber reinforcement methods evaluated, glass fiber reinforcement for the PMMA resin and bis-acryl composite resin materials produced highest flexural strength. CLINICAL IMPLICATIONS: On the basis of this in-vitro study, the use of glass and polyethylene fibers may be an effective way to reinforce provisional restorative resins. When esthetics and space are of concern, glass fiber seems to be the most appropriate method for reinforcing provisional restorative resins.

Chronopharmacokinetics of rifampicin.

Chronopharmacokinetics of rifampicin was studied in four healthy adult male human volunteers after drug (2.0 g) ingestion at 6.00, 12.00, 18.00 and 24.00 hr. The absorption rate constant was found to be lower and the time to reach peak concentration was longer after drug administration at 24.00 hr than at other dosing times. A second peak was observed in all individual volunteers between 6-12 hr after drug dosing at 24.00 hr. This may be due to the influence of biliary rhythms on the disposition kinetics of rifampicin.

Relation between electrokinetic potentials and growth in callus cultures of Trigonella foenum-graecum.

Callus cultures of Trigonella foenum-graecum were initiated from radicle or cotyledon portions of seedlings and young leaves and maintained on modified 1-B5 medium. The callus mass was disaggregated by mechanical agitation and the discrete cells thus obtained were used to measure their electrokinetic potential. Studies pertaining to the effects of ageing on electrokinetic potential and growth index revealed a relationship between these two parameters. Thus, the rate of change of electrokinotie potential with age could be employed as a parameter to study the growth kinetics of cells in callus cultures.

Bioavailability of sulfathiazole from flocculated and deflocculated suspensions and its implications.

Flocculation is commonly used to stabilize pharmaceutical suspensions. Flocculated and deflocculated suspensions of sulfathiazole were administered to healthy human volunteers. Bioavailability from these two types of suspensions was studied from urinary free drug excretion. Bioavailability was significantly lower from flocculated suspensions. The study indicates the necessity of studying all flocculated drug suspensions for bioavailability data.
