Comparative evaluation of three different recording criteria of dental fluorosis in a known endemic fluoride area of Haryana

Background & objectives: Various indices are available to record different grade of severity of dental fluorosis. These indices have chances of inter- and intra- examiner variability. Therefore, study was conducted to compare three different indices for recording dental fluorosis to find out the best and most practical index of recording dental fluorosis for field studies in children living in a fluoride endemic area. Methods: The severity grades were recorded in 300 schoolchildren aged 12-15 yr having dental fluorosis of low, medium and high fluoride areas using three different indices, viz. Dean's fluorosis index (1942), tooth surface index for fluorosis (TSIF, 1984) and ICMR index (2013). Dean's index was used as gold standard. Results: The occurrence of moderate and severe cases was higher as per the Dean's index and of mild and severe cases was higher as per the TSIF and the ICMR index. The mean time required for recording dental fluorosis as per Dean's index and TSIF was similar and almost double (1.25�05 min) of that required for ICMR index (0.68�20 min). The intra-examiner variability was found to be least in the ICMR index compared to Dean's index and TSIF. Interpretation & conclusions: The ICMR index is a simple index with objective scores and takes less time in recording the dental fluorosis as compared to Dean's index and TSIF in field studies.

Effect of a Comprehensive Training Programme for Tuberculosis Health Care Providers and Tuberculosis Patients on Diabetes – A Report from South India.

Aims: High prevalence of diabetes mellitus (DM) in TB patients demands that TB health care providers are sensitized and updated on risk factors, screening, diagnosis and management of DM. This study was designed to assess the impact of one day training programme on screening, detection and management of DM. Study Design: One group – pre and post test design. Place and Duration of Study: The one day training session with an inbuilt awareness programme was conducted for TB health care providers and TB patients with diabetes, over a period of 3 years, from since November 2010 involving 22 tuberculosis units of 3 districts in Tamil Nadu, India. Methodology: The impact was assessed using a pretested questionnaire pre and post training, based on the improvement in knowledge among physicians and other health care providers and awareness among patients. Similarly, using a separate questionnaire before and six months after the training programme, improvement in practice was assessed based on an increase in the proportion of staff involved in screening, educating and referring TB patients with diabetes. Appropriate statistical analysis was done using SPSS version 16. Results: There was a significant increase in the knowledge of physicians and other health care providers and in patient’s awareness on all components covered under the training and awareness session respectively. No significant improvement was noted in the knowledge of other TB health care providers, in diet category on the questionnaire. There was a significant improvement in practice based on the substantial increase in the proportion of tuberculosis unit staff conducting DM screening for TB patients using appropriate methods and in referrals for proper management of DM. Conclusion: The training session on DM with an inbuilt awareness campaign for TB patients had a significant impact on the knowledge and practice of TB health care providers.

Orthodontic management of faciolingual horizontally impacted maxillary central incisor.

This paper describes the successful alignment of a horizontally impacted maxillary central incisor positioned high in the vestibule, in a 15-year-old girl, by purely orthodontic means. A unique and innovative technique for traction was employed so as to cause minimal injury to the neighboring soft tissue. The article is a step forward in establishing the predictability of orthodontic alignment in management of such cases, which may become the method of choice over extractions or surgical repositionings.

Early class III occlusal tendency in children and its selective management.

Class III malocclusion may develop in children as a result of an inherent growth abnormality, i.e., true class III malocclusion, or as a result of premature occlusal contacts causing forward functional shift of the mandible, which is known as pseudo class III malocclusion. These cases, if not treated at the initial stage of development, interfere with normal growth of the skeletal bases and may result in severe facial deformities. The treatment should be carried out as early as possible with the aim of permitting normal growth. This paper deals with the selection of an appropriate treatment approach from the various current options available for early intervention in children developing class III occlusal tendencies; the different clinical features are depicted in the three case reports.

Management of inverted impacted primary incisors: an unusual case.

The prevalence of impacted primary teeth has been reported to be very rare and it has been reported to occur in 1:10,000 times, most commonly involving the primary second molars. This report discusses the presence of an impacted inverted maxillary primary incisors and their management by surgical intervention in a 5 year old boy. The inverted primary maxillary central incisors were extracted and prosthetic rehabilitation was done to improve the esthetics, speech and psychosocial behaviour of the child. Co-incidentally the permanent maxillary incisors were also found to be hypoplastic although the parents did not give any history of trauma to the maxillofacial complex. It is important for pediatric dental surgeons to carefully monitor the eruption of primary and permanent teeth for early identification and management of developmental anomalies.

Barriers to changing dietary behavior.

Dietary change requires giving up long established patterns of eating behavior and acquiring new habits. 'Non-compliance' to diet advice may be a result of inability to provide diet self-management training and getting the right messages across to change eating behavior. Using a pre-tested questionnaire based interview, we carried out a study amongst 350 adults (> 20 years) with type 2 diabetes from two metro cities in South India, who had previously received diet advice with the objective to understand perceptions, attitudes and practices, as well as study factors that enhance or reduce compliance to diet advice. Ninety six patients (28%) followed diet for the full duration of diabetes (Group1), 131 (38%) followed diet for a partial duration varying between more than a quarter to three quarters of the total diabetes duration (Group 2) and 115 (34%) did not follow diet advice (Group 3) - followed for a duration less than a quarter of their diabetes duration. Study results show that many factors both patient and health care provider related influence outcomes of dietary advice. Factors that have a positive impact on compliance are - older age, shorter duration, nuclear family, good family support, less busy work life, higher health consciousness, advice given by dietician, more frequent visits to dietician, advice that includes elements to promote overall health not merely control of blood sugar, diet counseling that is easy to understand and use and includes healthy food options, cooking methods, practical guidance to deal with lifestyle issues. We conclude that patient barriers related to life circumstance are mostly non-modifiable, most modifiable barriers are related to behavioural aspect and the inability of the health care provider to provide individualized diet advice and self management training. Efforts must be made to improve counseling skills.

Epidemiology of dental caries in Chandigarh school children and trends over the last 25 years.

The prevalence of dental caries in 6, 9, 12 and 15-year-old school children of Chandigarh, selected on a randomized basis was evaluated using Moller's criteria (1966) and correlated with the various risk factors. The mean deft was found to be 4.0 +/- 3.6 in 6 year old and 4.61 +/- 3.14 in 9 year old, whereas the mean DMFT in 12 and 15 year old was found to be 3.03 +/- 2.52 and 3.82 +/- 2.85 respectively. The high prevalence of dental caries in these children was attributed to the lack of use of fluoride toothpaste (80% children), lack of knowledge about etiology of dental caries (98%) and frequency of sugar exposures up to more than five times per day (30%).

Awareness and knowledge of diabetes in Chennai--the Chennai Urban Rural Epidemiology Study [CURES-9]

BACKGROUND AND AIM: There are virtually no epidemiological studies from India assessing the level of awareness of diabetes in a whole population. The aim of the present study was to assess the awareness of diabetes in an urban south Indian population in Chennai. METHODS: The Chennai Urban Rural Epidemiology Study (CURES) is an ongoing population based study conducted using a systematic sampling method on a representative population (aged > or = 20 years - 26001 individuals) of Chennai [formerly Madras], the largest city in Southern India. A structured questionnaire was used to obtain information related to demography, education and medical history. The questionnaire included five questions on diabetes awareness. RESULTS: Of the total 26,001 individuals, only 75.5% (19642/26001) of the whole population reported that they knew about a condition called diabetes or conversely nearly 25% of the Chennai population was unaware of a condition called diabetes. 60.2% (15656/26001) of all participants and 76.7% (1173/1529) of the self reported diabetic subjects knew that the prevalence of diabetes was increasing in India. Only 22.2% (5764/ 26001) of the whole population and 41.0% (627/1529) of the known diabetic subjects were aware that diabetes could be prevented. Knowledge of the role of obesity and physical inactivity in producing diabetes was very low, with only 11.9% (3083/26001) of study subjects reporting these as risk factors for diabetes. Only 19.0% (4951/26001) of whole population knew that diabetes could cause complications. Even among the self reported diabetic subjects, only 40.6% (621/1529) were aware that diabetes could produce some complications. CONCLUSION: Awareness and knowledge regarding diabetes is still grossly inadequate in India. Massive diabetes education programmes are urgently needed both in urban and rural India.

Efficacy and acceptabilty of oral-transmucosal midazolam as a conscious sedation agent in pre-school children.

The purpose of the present study was to test the efficacy of oral-transmucosal route of administration of midazolam in young potentially un-cooperative children. A sample of 40 children up to 4 years of age with ASA I status were randomly divided into experimental and control groups of 20 each. The children in experimental group received 0.5-mg/kg-body weight midazolam mixed in strawberry syrup via the oral-transmucosal route and those in control group were given the same syrup diluted with normal saline. A class II amalgam restoration was performed and routine behavior management techniques were employed in both groups. It was found that the number of procedures successfully completed and sedation produced 15 minutes after test solution administration was significantly greater in the experimental group compared to the control group. The total treatment time was also much lesser in the experimental group children. There was no significant difference in the acceptability of the test solutions in the children of the two groups.

Age-specific prevalence and risk associations for impaired glucose tolerance in urban southern Indian population.

OBJECTIVES: A national survey of diabetes and impaired glucose tolerance (IGT) conducted in 2000 AD in six major cities of India showed a high prevalence of diabetes (12.1%) and IGT (14%). Prevalence of IGT was higher than that of diabetes in subjects with less than 40 years when compared with older subjects. This analysis was done to look for differences in the risk factors associated with IGT in the younger and older subjects. METHODS: Associations of body mass index (BMI), waist : hip ratio, physical activity, family history of diabetes and monthly income with IGT and with diabetes were tested in the age groups of < 40 and > or = 40 years separately. Multiple logistic regression analyses were done to test the associations. RESULTS: Prevalence of IGT was higher than diabetes in the younger group (13.1% Vs 5%, P < 0.001). Prevalence of obesity was higher in the older IGT subjects (38% Vs 30.5%, p < 0.003). Presence of positive family history of diabetes was similar in both the groups. In the > or = 40 year group age, BMI and family history of diabetes were common risk factors for diabetes and IGT. In the younger group, only BMI showed an association with IGT. The association of family history of diabetes with IGT was weaker than for diabetes even in the older subjects (Odds Ratio (OR) = 3.5 for diabetes, 1.33 for IGT). CONCLUSIONS: Prevalence of IGT was higher than diabetes in the age group < 40 years. Only BMI showed an association with IGT in them while the risk associations were similar to diabetes in the older group. Prospective studies will throw more light on the implications of these findings.

DiabCare Asia--India Study: diabetes care in India--current status.

AIM: To investigate the relationship between diabetes control, management and late complications in a subset of urban Indian diabetes population treated at tertiary diabetes care centres and measure the quality of management to set benchmarks for future improvement. METHODOLOGY: The study population consisted of 100 consecutive review patients treated for more than one year at each of the 26 participating centres. HbA1c was estimated centrally by Bio-Rad Variant method. The methods used to diagnose diabetic complications varied among centres, depending on the doctor's standard clinical examination. A more detailed methodology was eschewed for reason of brevity of the data collection form, and lack of standardisation of methods. Similarly, the assessment of renal function was performed via a variety of methods, namely dipstick proteinuria, a 24 hour urinary excretion assay, presence of microalbuminuria and serum creatiine concentration; retinopathy was detected using fundoscopy. Data was collected in a standardized data collection form, entered into an SAS database, validated and descriptive analysis performed. RESULTS: A total of 2,269 subjects with valid relevant data formed the study population. Subjects had a mean age of 53.3 +/- 13 years. The mean age at onset of diabetes was 43.6 +/- 12.2 years, with a mean diabetes duration of 10.0 +/- 6.9 years. Type 2 diabetics constituted 90.6% of the patients. Approximately half the patients had poor control (HbA1c > 2% points above upper limit of normal and FBG > 139 mg/dl). Mean HbA1c (central laboratory) was 8.9 +/- 2.1% and FBG 150 +/- 59 mg/dl. Over 54% patients had severe late complications, apart from a high frequency of associated hyperlipidemia. Mean HbA1c level and frequency of complications was higher in patients with longer diabetes duration. Frequency of self-monitoring was low. Only 4% of patients were on diet therapy, 53.9% were receiving oral hypoglycemic agents (OHAs), 22% were receiving insulin and 19.8% a combination of insulin and OHAs. Frequency of insulin usage was higher amongst patients with longer diabetes duration. CONCLUSIONS: This large multi-centre collaborative observational study shows that type 2 diabetes begins at an early age amongst Indians. With increasing duration of diabetes, glycemic control deteriorates leading to late complications. Diabetes care in India leaves much to be desired. Concerted efforts to increase awareness amongst health professionals to improve diabetes care are urgently needed. The study by increasing awareness about the current status of diabetes care provides a useful benchmark to plan future improvements.

Streptogramins: a new class of antibiotics.

Streptogramin antibiotics represent a unique class of antibacterials in the each member of the class consists of at least 2 structurally unrelated molecules: group a streptogramins (macrolactones) and group B streptogramins (cyclic hexadepsipeptides). Both group A and group B streptogramins inhibit protein synthesis at the ribosomal level, and they act synergistically against many isolates their combination generating bactericidal activities and reducing the possibility of emergencies of resistant strains. The mechanisms of acquired resistance to group B streptogramins remain unaffected by target modifications and active efflux. The pharmacokinetic parameters of group A and group B streptogramins in blood are quite similar. In addition, both the A and B group penetrate and accumulate in macrophages and in the bacterial gegetations of experimental endocarditis. Until recently, the complex and irregular composition of naturally occurring pristinamycin and virginiamycin, as well as the unavailability of soluble forms, have limited the clinical development of streptogramins. The synthesis of water soluble derivatives of pristinamycin IA and IIB has now allowed the development of injectable streptogramins with fixed compositions. This unique class of antibacterials will have a significant clinical impact in a world of increasing multidrug resistance affecting the Gram-positive cocci, especially staphylococci and pneumococci. The absence of cross-resistance to macrolides in many of these isolates and the rapid antibacterial killing against these species bright future for this class of antibiotics.

Effects of purified insulins on insulin requirement and metabolic control.

Seventeen diabetics requiring high insulin doses were transferred from conventional insulin to purified chromatographed porcine insulins (Actrapid and Lentard-Novo, Denmark). At the end of 8 to 12 weeks, there was a 46% reduction in insulin dosage while metabolic control improved. Some of these patients when transferred again to conventional insulins demonstrated poor metabolic control and an increase in insulin requirements. Use of purified insulin is beneficial as insulin requirement is reduced with improved metabolic control.
