The study found that the diagnosis given by the Injured Tooth App was in good agreement with the diagnosis given by an experienced faculty. Hence, the App can be successfully used by dental students to arrive at diagnosis.

BACKGROUND AND OBJECTIVES: The coronavirus disease (COVID-19) pandemic has broad implications for children and families. Particular attention has been paid to delays in accessing timely pediatric care leading to unintended morbidity. In this study, we aim to describe the broader spectrum of unintended negative consequences for pediatric patients and families due to recent health care and societal changes. METHODS: All full-time doctors, dentists, and nurse practitioners working at a tertiary care children’s hospital in Canada were surveyed every 2 weeks throughout the initial phase of the COVID-19 pandemic to identify clinical cases in which they perceived a negative outcome associated with hospital or societal changes as a result of the COVID-19 pandemic. Analysis followed a qualitative case series methodology using a narrative synthesis approach to determine similarities and associated themes. RESULTS: One hundred and forty-one clinicians, representing 26 hospital divisions, reported 57 unique cases in the first 6 weeks of the study. Thematic analysis of the first 50 reported cases was used to identify 6 primary themes focusing on health care quality domains as described by the Agency for Healthcare Research and Quality (safe, effective, patient-centered, timely, efficient, and equitable care). CONCLUSIONS: In this preliminary case analysis, we describe the broad social and clinical impact of COVID-19 on hospitalized pediatric patients and their families. These themes highlight the unintended consequence on families, siblings, disease diagnosis, and hospital-based care provision. Recognition and understanding of the broad implications of the COVID-19 pandemic are necessary as we strive to deliver safe, high-quality, family-centered pediatric care in this new era.

The present study described an improved and reproducible in vitro regeneration system for Terminalia arjuna using nodal segment explants obtained from a mature plant. Shoot tips excised from in vitro proliferated shoots were encapsulated in 3 % sodium alginate and 100 mM CaCl2[Symbol: see text]2H2O for the development of synthetic seeds which may be applicable in short-term storage and germplasm exchange of elite genotype. Shoot multiplication was significantly influenced by a number of factors, namely types and concentrations of plant growth regulators, medium composition, repeated transfer of mother explants, subculturing of in vitro regenerated shoot clumps, agar concentrations, and temperature. Maximum numbers of shoots (16.50 ± 3.67) were observed on modified Murashige and Skoog (MMS) medium containing 0.5 mg l(-1) of benzylaminopurine (BAP) and 0.1 mg l(-1) of naphthalene acetic acid (NAA). To shortening the regeneration pathway, rooting of micropropagated shoots under in vitro condition was excluded and an experiment on ex vitro rooting was conducted and it was observed that the highest percentage of shoots rooted ex vitro when treated with indole-3-butyric acid (IBA, 250 mg l(-1)) + 2-naphthoxy acetic acid (NOA, 250 mg l(-1)) for 5 min. The well-developed ex vitro rooted shoots were acclimatized successfully in soilrite under greenhouse conditions with 80 % survival of plants. Randomly amplified polymorphic DNA (RAPD) analysis confirmed that all the regenerated plants were genetically identical to the mother plant, suggesting the absence of detectable genetic variation in the regenerated plantlets. To the best of our knowledge, this is the first report on synthetic seed production as well as ex vitro rooting and genetic fidelity assessment of micropropagated shoots of T. arjuna.
