Improving dental-oral health learning in students using a mobile application ("My tooth"): A controlled before and after study.

OBJECTIVES: Tooth decay is one of the most common problems amongst students. Despite considerable educational interventions, it is still very prevalent. The aim of this study was to compare the effect of a dental-oral health mobile educational application with the common dental-oral health education amongst elementary school students. METHODS: This interventional study was carried out on 158 girl students in the age range of 10-12 years in Mobarakeh City, Iran. The participants were categorized into the intervention and control groups and investigated in the academic year of 2018-2019. The research tool was a researcher-made questionnaire with confirmed validity and reliability. Initially, all students completed the questionnaires. Later, the intervention group members were trained using dental-oral health mobile educational application and control group received the common dental-oral health educations in lectures and demonstrations. Two months after the last intervention, the same questionnaire was completed and data were analysed by SPSS software. RESULTS: Before the intervention, the mean score of behaviour was 13.69 ± 3.89 and 13.93 ± 3.02 (of 21) for the intervention and control groups. At this phase, the difference between the two groups was not significant in the studied dimensions (p > 0.05). After the intervention, mean scores of the intervention group increased significantly with regard to all variables (p < 0.05). CONCLUSIONS: Findings of this study confirmed the positive effect of learning through mobile applications on increasing the students' knowledge, attitude and performance regarding dental-oral health education.

Visceral Leishmaniasis (VL) Clinical Presentation, Laboratory Findings, Treatment Options and Outcome.

Background: Black disease, also known as visceral leishmaniasis (VL), is a parasitic illness caused by various Leishmania species. The risk of morbidity and mortality increases with delayed diagnosis and treatment. Early VL diagnosis and fast appropriate treatment are critical issues in endemic areas. Methods: This study was a retrospective cross-sectional study to investigate the diagnostic and therapeutic course of patients admitted with the diagnosis of VL in the Children's Medical Center (CMC) Hospital, Tehran, Iran. All cases of VL in patients under the age of 18 hospitalized between the years 2012 to 2022 were enrolled. Results: Twenty-seven patients were enrolled with an average age of 28.13 months with the majority of females (51.8%). Common clinical signs were fever (96.2%) and splenomegaly (92.59%). However, lymphadenopathy was rare. The largest number of patients was from Tehran Province, followed by Ardabil, Khuzestan, Gilan, and Alborz provinces. The most common hematological abnormalities were anemia (85.1%) and thrombocytopenia (44.4%). In accordance with the treatment strategy, liposomal amphotericin B and amphotericin B deoxycholate were given to 11 and 5 patients, respectively. Eleven of them received glucantime. The average length of hospitalization for liposomal amphotericin B was 15.36 ± 12.49 days. In comparison with glucantime (18.38 ±10.26 days) and amphotericin B deoxycholate (20.20± 6.18 days), liposomal amphotericin B group hospitalization was shorter than others were. Conclusion: VL should be included in the differential diagnosis of any child who presents with fever, splenomegaly, and anemia. Concerning the treatment strategy in this study, liposomal amphotericin B had more efficiency and shorter hospitalization duration.
