The aim of this study was to compare the efficacy of articaine versus lidocaine, both containing epinephrine, using a single buccal infiltration for extraction of primary molars.A total of 100 children requiring primary molar extraction received buccal infiltration using either 4% articaine or 2% lidocaine, both with epinephrine, with 50 children in each group. The Wong-Baker Facial Pain Scale (FPS) was used to evaluate pain perception subjectively. The heart rate and the blood pressure values were assessed objectively as an indirect measure of physiological pain perception. The Wilcoxon-Mann-Whitney test was used for comparing mean pain scores, heart rate, and blood pressure in both the groups. Single buccal infiltration with articaine was sufficient for achieving palatal or lingual anesthesia in all the children receiving it while all children in the lidocaine group required supplemental anesthesia. The mean FPS value was found to be higher in lidocaine group and was statistically significant. The mean heart rate recorded during the intervention was less than the mean baseline values in the articaine group, which was found to be statistically significant. For pediatric patients age 7 to 12 years, single buccal infiltration with 4% articaine with 1:100,000 epinephrine is more effective compared to 2% lidocaine with 1:80,000 epinephrine for primarly molar extraction.

This investigation is focused on the effect of exhaust gas recirculation (EGR) and injection timing on the performance, combustion and exhaust emission characteristics of common rail direct injection (CRDI) engine fueled with bioethanol-blended diesel using computational fluid dynamics (CFD) simulation. Simulation is carried out for various EGR rates (0, 10, 20 and 30%), two different injection timings, and two different bioethanol–diesel blends (10 and 20%) at injection pressure. The equivalence ratio is kept constant in all the cases of bioethanol–diesel blends. The results indicate that the mean CO formation and ignition delay increase, whereas mean NO formation and in-cylinder temperature decrease, with increase in the EGR rate. Further, with an increase in percentage of the bioethanol blends, CO and soot formation decrease as compared to neat diesel. A significant increase in in-cylinder pressure (15%) is found at 14° before top dead centre (BTDC) compared to 9° BTDC, which leads to an increa...

Introduction: Children with special health-care needs have limitations in oral hygiene performance due to their potential motor, sensory, and intellectual disabilities and so are more prone to have compromised oral health. Aim: This study aimed to compare the impact of oral hygiene instructions given via sign language and a validated customized oral health education skit video on oral hygiene status of children with hearing impairment (CHI). Settings and Design: Ethical clearance was obtained from the institutional ethical committee for research activities. The study was carried out across CHI schools of Wardha district, Maharashtra, India. Methodology: Sixty-eight CHI, within the age group of 6–13 years, were divided into two educational intervention groups: customized oral health educational video (Group A) and sign language (Group B). A structured questionnaire was designed to gather information about the routine oral hygiene practices via the Indian Sign Language. Baseline Gingival Index (GI)-S and Plaque Index-S indices were recorded. Based on the group assigned, oral hygiene instructions were given on a daily basis. Reassessment was done after 4 weeks. Statistical Analysis: Unpaired t-tests were performed (P < 0.05) to determine if significant differences exist between the two groups. Results: Postintervention plaque scores between Group A and Group B were 0.12 ± 0.22 and 0.07 ± 0.22, respectively, and the difference between the two was statistically insignificant (P = 0.330). For GI, scores in Group A and Group B were 0.03 ± 0.12 and 0.04 ± 0.12, respectively, and the difference was statistically insignificant (P = 0.669). Conclusion: Both sign language and the validated customized video modeling have been proved to be positively influencing the oral hygiene status of CHI equivalently.

Odontogenic keratocysts (OKC) are keratinizing epithelium-lined cycts of the jaws with well-defined histologic criteria and possessing one clinical feature warranting their recognition and separation as a distinctive entity, due to their exceedingly high recurrence rate. This report describes a case of OKC which occurred in the anterior maxilla in a 12 year old female child, with its treatment. These lesions are normally seen in the mandible, and are rare in the maxilla.

Occasionally, insect bites producing systemic complications are the reason for admission to paediatric intensive care. We report an interesting case of multiple bee stings in a 2-year-old boy. The boy, who was stung more than 200 times by honey bees, had a severely deranged coagulation profile with marked elevation of the hepatic enzymes. This complication has not been reported to date. Prompt intensive supportive care led to the child's total recovery. Language: en

Painful restricted movements of the extremities, hyperpigmentation over swollen joints, and a sclerema-like feel to the skin with increased serum triglyceride was seen in a 5-month-old baby with postnatal CMV infection. In an infant with pseudoparalysis of the limbs, the possibility of CMV infection has to be considered.

Serum apolipoproteins A (Apo-A) and B (Apo-B) and lecithin: cholesterol acyl transferase (LCAT) activities and 24-hour urinary cholesterol levels were estimated in 25 nephrotic children before and during steroid treatment with 4 weeks of daily prednisolone followed by another 4 weeks of alternate-day prednisolone. The patients with untreated nephrotic syndrome (NS) showed significant decrease in serum Apo-A and LCAT activities associated with significant increase in serum Apo-B and urinary cholesterol levels compared to healthy controls (n = 25). Serum Apo-A levels correlated directly and Apo-B levels inversely with the serum albumin concentrations. After a transient elevation, the serum Apo-A level returned to control range by 8 weeks of treatment accompanied by a gradual increase in serum LCAT activity and decrease in urinary cholesterol excretion. Though, the serum Apo-B level was decreased with treatment, it was still significantly high compared to the controls.
