Introduction: Public awareness of the COVID-19 pandemic has resulted in a reduction in healthcare utilisation for other diseases. Understanding how the COVID-19 pandemic affects hospital admissions and the disease patterns is crucial for proper triaging and planning of health resources in future pandemics. Aim: To compare the clinical spectrum of paediatric inpatients in the post-COVID-19, pre-COVID-19 and during COVID-19 pandemic periods in a tertiary level teaching centre. Materials and Methods: This ambispective study was conducted at the Paediatrics Department of SAT, Govt. Medical College, Thiruvananthapuram, Kerala, India. The analysis included all cases hospitalised from April 2019 to March 2022, with the data divided into three time periods. The discharge diagnoses of all cases admitted during the study period were coded according to the ICD-10 criteria and included in the analysis. Differences in admissions, disease patterns, and ICU admissions during the three time periods (pre-COVID-19, post-COVID-19, and during COVID-19) were compared using oneway ANOVA and Tukey's post-hoc test. Results: In the present study, ward admissions (p-value <0.001), respiratory infections (p-value 0.031), asthma (p-value 0.009), and chronic systemic diseases (p-value 0.018) decreased in the post-COVID-19 period compared to the pre-COVID-19 period, whereas ICU admissions (p-value 0.010) and Diabetic Ketoacidosis (DKA) (p-value 0.002) increased. When comparing COVID-19 and post-COVID-19 periods, there was an increase in ward admissions (p-value 0.01), respiratory infections (p-value 0.018), and diarrhoea (p-value 0.029), but a decrease in the proportion of ICU admissions (p-value 0.01). There was no significant difference in mortality among the three time periods. Conclusion: There was a significant difference in the clinical spectrum of paediatric inpatients. The significant decrease in admissions of chronic systemic diseases, which require regular follow-up for management changes, raises concerns about the potential impact on patient care.

Introduction: The success of root canal procedures depends on cleaning and shaping of canals. There are several instrumentation techniques available for root canal preparation. Recently, exclusive rotary file systems called Kedo-SG Blue and Prime-Pedo have been introduced for root canal preparation in primary teeth. The inherent flexibility of these files allows them to preserve the anatomy of curved canals in primary molars. Aim: To compare the instrumentation time, obturation time, and quality of obturation using two paediatric rotary file systems, Kedo-SG BlueTM and Prime-PedoTM, in mandibular primary molars. Materials and Methods: A randomised clinical trial was conducted in the outpatient Department of Paediatric and Preventive Dentistry, Narayana Dental College and Hospital, Nellore Andhra Pradesh, India, from February 1, 2019 to January 20, 2020. Fifty primary molars with necrotic pulp were included and randomly divided into two groups, with 25 teeth in each group. Group 1 and Group 2 were instrumented with Kedo-SG BlueTM and Prime-PedoTM, respectively. The time taken for instrumentation and obturation was noted in minutes, and the quality of root canal filling was recorded as optimal, underfilled, or overfilled. The data were statistically analysed using an independent Student's t-test for time measurements and a Chi-square test for the quality of obturation. Results: There was a statistically significant difference in instrumentation time and obturation time between the two groups (p-value=0.009; 0.011). The Kedo-SG BlueTM rotary system showed a better quality of obturation compared to the Prime-PedoTM rotary system, although the difference was not statistically significant (p-value=0.22). Conclusion: The Kedo-SG BlueTM rotary system demonstrated shorter instrumentation and obturation times, as well as a higher number of optimally filled canals compared to the Prime-PedoTM rotary system. Therefore, the Kedo-SG BlueTM rotary system exhibited better clinical performance in primary molars than the Prime-PedoTM rotary system. [ABSTRACT FROM AUTHOR]

Introduction: The overall incidence of cholecystitis in children appears to be increasing although the exact frequency of acute and chronic cholecystitis among children in India or worldwide remains unknown. The frequency of paediatric cholecystitis has proportionally increased with the childhood obesity and intake of habitual fatty food. Aim: To present the histopathological concordance of Laparoscopic Cholecystectomy (LC) performed among children for a clinical diagnosis of Gallbladder (GB) disease. Materials and Methods: A single centre retrospective study was performed including histopathological and relevant clinical data of all paediatric LC performed at Career Institute Of Medical Sciences and Hospital, Lucknow, Uttar Pradesh, India, between January 2019 to January 2022. Paediatric patients who had undergone LC in the designated time period for a clinical diagnosis of cholelithiasis and/or inflammatory GB disease with classical signs of inflammation were included. Study population with LC procedure submitted for histological evaluation were identified by performing an electronic search through the archives of Department of Pathology, Career Institute of Medical Sciences and Hospital, Lucknow, Uttar Pradesh, India, followed by a manual review of GB specimens, histopathology slides and reports. Results: Among 265 patients who underwent LC during this period, there were 62 (23.4%) children. The average age of presentation was 13 years (range 5-18 years), Forty nine (79%) were girls and 13 (21%) were boys. The clinical diagnosis for which paediatric LCs were performed were cholelithiasis among 51% and cholecystitis among 48%. On histopathological concordance these turned out to be chronic cholecystitis among 98.4% children among which 51% were associated with cholelithiasis. Calculous cholecystitis was more frequent than acalculous cholecystitis. Chronic cholecystitis with cholelithiasis and cholesterolosis was more frequent among adolescent girls. Conclusion: This study suggests that chronic cholecystitis accounts for the majority of inflammatory diseases among children undergoing LC for a GB disease and may or may not be associated with cholelithiasis. Chronic cholecystitis with cholelithiasis and cholesterolosis seem more frequent among adolescent girls. [ABSTRACT FROM AUTHOR]
