MacroAT after SR-CHD requires a large area of low voltage containing >/=2 scars forming narrow channels. Ablation within the channels eliminates MacroAT.

Serum cTnI rises occur in the majority of patients after multiple (>3) spontaneous ICD discharges but are due to acute coronary syndrome only 14% of the time (22% of the time in patients with known coronary artery disease).

Introduction:The premature loss of primary teeth may reduce arch length required for the succeeding tooth and, hence, predisposes crowding, rotation and impaction of the permanent teeth. There are only limited studies carried out about the prevalence of early loss of primary teeth.Aim:The present study was performed to evaluate the prevalence of early loss of primary teeth in school children in Chidambaram town in Tamilnadu, India.Settings and Design:A total of 1121 school children (561 boys and 560 girls) between 5 and 10 years of age were selected for the study.Materials and Methods:An experienced examiner performed all clinical examinations under natural light. Data including age and missing tooth was collected.Statistical Analysis Used:Microsoft Excel/2000 (Microsoft Office XP) data spreadsheet was used and later exported to the Statistical Package for Social Science (SPSS) for Windows (version 10.0). Descriptive statistics was applied and, from the results, chi-square tests were applied at a level of significance of 5% (P < 0.05). Results and Conclusions: The results showed that 16.5% of the sample had early loss of primary teeth, but no differences were observed between genders (P > 0.05). The greatest prevalence was found among the 8-year olds (5.08%), and the most commonly missing teeth were the right lower primary first molars (16.82%). It can be concluded that the prevalence of early loss was high and that the lower primary molars were the most commonly missing teeth in the present study

The dental health of preschool children has extensive implications on the oral heath of the individual as he grows into an adult. Parents/guardians of preschool children play a central role in enforcing proper oral hygiene and preventive regime in these children. This study was conducted with the aim of describing the views of parents/guardians about the dental health of pre-school children. Response was obtained on a 21 point questionnaire from randomly visiting parents of the outpatient section of Rajah Muthiah dental college and Hospital, Annamalainagar, India. The findings of the present study point towards poor awareness among the parents/guardians of preschool children, pertaining to their childs' oral health and this could directly translate to poor oral health among the children in this area.

Cryoablation for AVNRT using a focal 6-mm catheter was safe and effective. It resulted in a low risk of recurrence over 6 months of follow-up with no incidence of AV block requiring permanent pacing.
