Résumé
Context: Fracture of endodontically treated teeth is a grave sequela that a clinician should seriously ponder. Suitable selection of restorative materials is a requisite for long?term clinical success. Aims: To compare the fracture resistance of endodontically treated teeth restored with three different posts luted using two different cements under all ceramic crowns. Settings and Design: This in vitro study was conducted in the Department of Prosthodontics, Government Dental College, Kottayam, Kerala, India. Methods and Material: Thirty endodontically treated single?rooted mandibular premolars in which post spaces were prepared and divided into three different groups. Group 1 (n = 10): zirconia post group. Group 2 (n = 10): quartz fibre post group. Group 3 (n = 10): glass fibre post group. Each group is sub?divided into two based on the luting system: resin?modified glass ionomer cement (RMGIC) or dual?cure resin cement (DCRC). The fracture resistance testing was performed in a universal testing machine with a crosshead speed of 0.5 mm/min. Statistical Analysis Used: The mean fracture resistance were analysed using independent sample Student t?test and one?way ANOVA. Results: Within the zirconia post group, the mean fracture resistance was higher in DCRC sub?group compared to the RMGIC sub?group and the difference was statistically significant (p = 0.017). The difference in fracture resistance between three different post systems was not found to be statistically significant with respect to both the luting systems. Conclusions: It was observed that when zirconia post is used, the mean fracture resistance was higher in dual?cure resin group compared to the resin?modified GIC group.

Background: Asymptomatic bacteriuria in pregnancy should be screened and treated to reduce the risk of morbidity and mortality. Urine culture is the recommended test. In low resource setting with large patient load urine culture in all pregnant patients is not feasible. In this study authors have assessed the validity of urine microscopy in the screening of asymptomatic bacteriuria in pregnancy.Methods: Midstream clean catch urine specimen collected from 675 pregnant women was subjected to urine sediment microscopy and culture. It was considered screen positive if pus cells were >5/HPF. Asymptomatic bacteriuria was diagnosed if there were >/=100000 CFU of a single uropathogen per ml. Results obtained were statistically analysed for the prevalence of asymptomatic bacteriuria, sociodemographic and medical risk factors, causative organisms, antibiotic sensitivity and validity of urine sediment microscopy in detecting asymptomatic bacteriuria.Results: The incidence of asymptomatic bacteriuria in our study was 10.2%. The incidence was higher in the age group between 20-30 years, in gravida 3 and above, in upper lower and lower socioeconomic status, in women with hyperglycemia in pregnancy and anaemia. E. coli was the commonest bacterial isolate in culture positive cases. Bacterial isolates had poor sensitivity for Ampicillin, amoxicillin and nitrofurantoin and good sensitivity for cephalosporins and aminoglycosides. The sensitivity, specificity, positive and negative predictive values for urine microscopy was 43%, 85%, 25% and 93% respectively.Conclusions: This study shows poor sensitivity and positive predictive value and good specificity and negative predictive value.
Résumé
Background: Menstrual cup is an alternative to sanitary pads, which has received attention in relatively small-scale studies in high income, and low- and middle-income countries, including among schoolgirls. Made of high-grade medical grade silicone (biodegradable) have the advantage of reuse, and can potentially last up to 10 years. Objective of this study was to assess and analyse the awareness regarding menstrual cup among the women of reproductive age group.Methods: Data collected from the selected eligible participants by an interviewer administered study proforma. It is a descriptive cross-sectional study over 1 month in women in reproductive age in A. J. Institute Mangalore, Karnataka, India.Results: A total 82% were aware about menstrual cup but only 2.6% have used it.Conclusions: One challenge of menstruation that is taken for granted in affluent countries is the simple question of how to manage or contain the menstrual flow and what happens to a girl or woman who is not able to do this successfully. Menstrual hygiene management is therefore an increasingly important (yet often unrecognized) issue that is heavily intertwined with girls’ education, empowerment, and social development.
Résumé
Introduction: Many factors of tooth loss will compromise chewing and general health and quality of life. Saudi populations demonstrate a high prevalence of caries and a striking increase in dmft/DMFT. Usually, tooth loss is rehabilitated by different prosthetic options including implant, fixed partial denture and removable partial denture. Aim: To evaluate the relation of oral health-related quality of life with the type of prosthesis and oral health status among patients who have removable or fixed partial dentures in King Saud bin Abdulaziz University for health science, college of dentistry. Material and methods: Cross-sectional study would be conducted at the College of Dentistry, King Saud bin Abdulaziz University (KSAUHS) and Dental Centre, KAMC, NGHA. Convenient sampling was carried out by selecting 109 patients from those who visited the dental clinic. Oral health status was captured using the DMFT index. The collected data were entered and analyzed by adapting the SPSS computer software. Result: The type and quality of prosthesis and its effect on the OHRQoL on patients showed no significant relation (p=0.459), but the duration of wearing of prosthesis showed significant relation (p=0.046). Regarding DMF total of (n=109), 61 had low DMF, 48 had high DMF witch was statically significant (p=0.02). Conclusion: At the end of this study we conclude that there were no significant impacts on quality of life in relation to the type of prosthesis. On the other hand, we found a significant relation with OHRQoL in function domain, esthetic part and oral health status.

Background: Malaria is a global health problem leading to huge morbidity and mortality. India accounts for 4% of global malaria cases and 52% of malaria deaths outside the African region. A disease that was relatively unknown in Mangaluru till 1990, has shown consistent rise till 2015 killing nearly 300 people. Though, declining trends are being observed since 2015, yet its incidence continues to be high. Present study was undertaken to study clinical as well as epidemiological factors associated with malaria transmission in Mangaluru.Methods: A record based retrospective study was conducted in A J Institute of Medical Sciences and Research Centre Mangaluru tertiary care hospital. The data was retrieved from the Medical Record Department of the hospital for three years i.e. 2015 to 2017 and analysed.Results: A total of 1779 confirmed cases of malaria were admitted during the study period. Out of these 1309 (73.58%) cases were due P. vivax, 73 (04.10%) cases due to P. falciparum 306 (17.20%) cases had mixed infections while species of remaining 91 (05.11%) cases remained unspecified. A peak in the number of inpatients was seen in June while mean duration of hospital stay was 5.17±3.31 days. A total of 252 (14.16%) patients had one or more severe manifestations of malaria as per WHO guidelines.Conclusions: The present study reveals that majority of admitted malaria cases were young adult males belonged to urban area. Majority of the cases were infected by Plasmodium vivax or had mixed infections.
Résumé
The present study was investigated to explore the antibacterial activity of four different solvent (petroleum ether, chloroform, acetone and ethanol) crude extracts of marine brown seaweed Sargassum wightti. Crude extracts were screened against human pathogen Bacillus cereus. The antibacterial efficiency was performed by agar well diffusion, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) methods. The results revealed that the crude extract of petroleum ether showed prominent inhibiting activity against B. cereus andother crude extracts showed below detectable level. The highest microbicidal activity (zone of inhibition) 9.0 ± 0.32 mm was obtained at the concentration of 250 μg /ml and the lowest activity was 3 ± 0.20 mm at 31.25 μg /ml concentration. The MIC and MBC values were found to be 125 and 250 μg /ml respectively. Results of this study suggested that the compounds present in the crude extracts of petroleum ether showed high activity against B. cereus and further studies are required to purify the active principles.

Résumé
An important reason for higher cervical cancer incidence in developing countries is lack of effective screening programs like pap smear, aimed at detecting precancerous conditions before they progress to invasive cancer. The potential difficulties in implementing cervical cytology based screening in low-resource settings have prompted the investigation of accuracy of alternative low technology tests such as Visual inspection with acetic acid application [VIA], Visual inspection with acetic acid application with magnification [VIAM], visual inspection on Lugol’s Iodine application [VILI] in early detection of cervical neoplasia .In our study we compared pap smear with VIA to study the accurarcy of VIA as it is simpler and easier technique to be used as screening in low resource settings. Aim: This is a hospital based descriptive, prospective study to evaluate validity of pap smear and VIA techniques as screening tests in identifying cervical lesions. Materials And Methods: After general and systemic examination as a routine,visual local pelvic examination including visualisation of cervix and vagina per speculum and the findings are documented in the proforma .Then VIA and pap smear are done in that order, if any of these tests are positive then cervical biopsy will be taken and further advise to the subject is given. Results: A total of 313 women were involved in the study. The sensitivity of pap smear is 54.5% specificity is 98.9% while that of VIA 95.4% and 97.9%respectively. We found that VIA accuracy was comparatively more than that of pap smear. Conclusion: In low resource settings, usefulness of VIA is more than that of pap smear. We suggest to perform VIA in all the women inspite of having pap smear facility to improve detection rate of cervical lesions and provide better patient councelling and treatment.
Résumé
Anxiety is a cardinal symptom of many psychiatric disorders and an almost inevitable component of many medical and surgical conditions. Indeed it is a universal human emotion, closely allied with appropriate fear presumably serving pyschobiologically adaptive purposes. Anxiety is a normal emotional behaviour. When it is severe and/or chronic, however, it becomes pathological and can precipitate or aggravate cardiovascular and psychiatric disorders. Although many drugs are available in allopathic medicine to treat anxiety disorders, they produce various systemic side effects. Ursolic acid has been identified as the active principle of Ocimum sanctum. From our laboratory we have established the antianxiety, anticateleptic and antidepressant activity of ethanolic extract of leaves of Ocimum sanctum. In the present study, we have attempted to evaluate the anxiolytic- activity of ursolic acid in rats by employing, elevated plus maze and bright and dark arena. The rats were divided into five groups, each group containing six animals. The effects of the test drug ursolic acid (at 0.05, 0.1 and 0.2 mg/kg doses), the standard anxiolytic, diazepam (1.0 mg/kg) and control group 14% dimethyl sulfoxide (10ml/kg) were assessed after repeated doses administration for ten days. The results suggest that, ursolic acid exhibited anxiolytic like activity comparable to diazepam.
Résumé
Vitamin B12 deficiency has been implicated in various psychiatric conditions for a long time. The association could be primary, secondary to the psychiatric disorder, or even just coincidental. However, left untreated, the deficiency can delay or preclude recovery. Hence early recognition is important, especially when the traditional manifestations of B12 deficiency like anaemia, macrocytosis or spinal cord symptoms are not prominent. Three cases are presented here where vitamin B12 deficiency and psychiatric symptomatology were coexistent, and the patients recovered only on a combination of B12 supplementation and psychiatric medication.
