Prevalence of attention deficit hyperactivity disorder in school-going children in rural Konkan region of Maharashtra.

Background: Attention deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder of childhood characterised by attention deficit, hyperactivity and impulsiveness. The present study was designed to compute the prevalence of ADHD and assess the association of the predetermined demographic variables and ADHD in school-going children aged 6-12 years in rural areas of Konkan. Material and Methods: The present study was a descriptive, cross-sectional study. Using the first edition of Vanderbilt's scale - D4 (Teacher's informant) by National Institute for Children's Health Quality (NICHQ) for identifying symptoms of ADHD in children, a questionnaire was filled out for each child with input from their class teacher. These data were then compiled and analysed. Results: Out of the 133 participants in the study aged 6-12 years, the gender distribution was 69 boys and 64 girls. The mean age was 9.2 ± 2.3 years. Of which, one student (0.75%) was found to have a predominantly inattentive subtype of ADHD (ADHD-IA). The prevalence was found to be 1.5% (2/133). In addition, one student (0.75%) was found to have a combined ADHD-IA and hyperactive (ADHD-H/I) subtype of ADHD (ADHD-C). The latter was also positive for the anxiety/depression screening scale administered as part of the same questionnaire. The total symptom score for questions 1-18 was 8.44 ± 7.29. Conclusion: One of the most common neurodivergent conditions among school-age children is ADHD. Using an easy-to-use questionnaire, teachers and parents can report those experiencing symptoms of ADHD. Early diagnosis and treatment are recommended to avoid complications and aid in the improvement of quality of life.

Assessment of QT Interval Abnormalities on Electrocardiogram in Children With Breath-Holding Spells.

OBJECTIVE: To assess QT interval abnormalities among children with breath-holding spells. METHODS: This case control study included 204 children (104 cases of breath-holding spells and 100 healthy children) younger than 3 years. Breath-holding spells were evaluated for age of onset, type (pallid/cyanotic), triggering factors, frequency and presence of family history. Twelve- lead surface electrocardiogram (ECG) was analyzed for QT interval (QT), corrected QT interval (QTc), QT dispersion (QTD) and QTc dispersion (QTcD) in milliseconds. RESULTS: The mean (SD) QT, QTc, QTD and QTcD interval in milliseconds were 320 (0.05), 420 (0.07), 61.15 (16.20), 102.3 (17.24), respectively for breath-holding spells as compared to control group [300 (0.02), 370 (0.03), 38.6(14.28), 78.6 (14.28), respectively] (P<0.001). Similarly, pallid breath-holding spells had prolonged mean (SD) QT, QTc, QTD and QTcD interval in milliseconds [380 (0.04), 520 (0.08), 78.88 (10.78), 123.33 (10.28), respectively] as compared to cyanotic spells [310 (0.04), 400 (0.04), 57.44 (14.64), 97.90 (15.03), respectively] (P<0.001). The mean QTc interval was 590 (0.03) and 400 (0.04) milliseconds in prolonged and non-prolonged QTc group, respectively (P<0.001). CONCLUSION: Abnormal QT, QTc, QTD and QTcD were observed among children with breath-holding spells. ECG should be strongly considered, especially in pallid, frequent spells occurring at younger age and having positive family history, to identify long QT syndrome.

Impulse Oscillometry System for the Diagnosis of Wheezing Episode in Children in Office Practice.

Background and Objective: Objectively differentiating between wheezing episodes and other respiratory disorders will be helpful in treatment in office practice. The impulse oscillometry system has been useful in assessing airway resistance in children 3-6 years old. As the reference values are different in geographical regions the use of the impulse oscillometry is still limited. Comparison between the percent change in IOS parameters as compared to reference standards and changes in actual IOS parameters was done to diagnose wheezing episodes. Methodology: Three to six years old children with a history of fever, cough, cold, and/or breathlessness with noisy breathing and who were not on any regular medications, whose parents gave consent were recruited in the study. The children underwent an impulse oscillometry system examination as per the guidelines. The test was repeated after they were given nebulization by salbutamol (2.5 mg) (before COVID 19 pandemic). Final diagnosis was done by following patients for 7 days. Results: About 106 children were recruited in the study. Five children could not perform the IOS test. Eighteen children did not complete the follow-up. Hence, 83 children were analyzed. There were 47 males and 36 female patients. The change in actual values of AX, R5, and X20 showed statistically significant difference in wheezing episode group (p-value<0.001). The percentage change as compared to predicted values of R5 and X20 also showed a statistically significant difference in the wheezing episode group and the others group (p-value<0.001). Conclusion: The change in actual values of AX, R5, X20, and resonant frequency may help to differentiate wheezing episode from other respiratory diseases.

Assessment of preferable site for temperature measurement using non contact infra-red temperature among pediatric patients.

BACKGROUND: Accurate temperature measurement with little or no discomfort that is safe, without risk of hospital-acquired infections or perforations, is the preferred choice of medical professionals in pediatric settings. The objective was to discover the preferable site for body temperature measurement using non-contact infra-red thermometer (NCIT) among pediatric patients. METHODS: NCIT measurement at mid forehead (F), right temporal region (T), right side of neck- over-carotid artery area (N), jugular notch (J), sternum (S), umbilical region and sublingual region (U) were compared with digital axillary temperature (DAT) in a single attempt in 500 patients, aged between 2 to 5 years with fever. Data was analyzed using Pearson's correlation, paired T-test and Bland-Altman plot to assess the correlation and agreement between the DAT and NCIT sites. RESULTS: The mean temperature of NCIT-T (38.42 ± 0.64 °C) was more agreeable with DAT (38.42 ± 0.63 °C) compared to other body sites. The minimum mean bias of -0.00480 °C was noted for NCIT-F with 95% CI of -0.164-0.15; however, NCIT-F revealed many outliers as compared to NCIT-J. A strong positive correlation existed between DAT and NCIT sites (r value: 0.99-0.98). However, significant difference was found between DAT and NCIT-N, NCIT-F and NCIT-U (p value < 0.0001). CONCLUSIONS: NCIT-J is the most preferable choice for measuring body temperature and can be interchanged with DAT. It will help to deliver fast results with enhanced patient comfort due to its non-invasive nature.
