Abstract Introduction: Physicians use mobile apps for patient care, but few are dedicated to pediatric critical care medicine (PCCM). We developed an easy-to-use customized mobile app for PCCM residents. Our objectives were to evaluate whether this mobile app will improve residents' confidence in PCCM knowledge and comfort level in the pediatric intensive care unit (PICU).Methods: We recruited 90 residents from March 2020 to April 2021 for this prospective survey-based, block-randomized, single-center study with a pre-post study design. Participants completed 20-question quizzes at the beginning and end of the rotation. T-test was used to compare the pre-post quiz score difference between the two groups of residents (those with and without the app). At the end of the rotation, subjects also completed a survey with 5-point Likert scale items to compare their comfort level in PICU and confidence in PCCM knowledge pre- and post-rotation.Results: There was a significantly increased improvement in the post-block quiz from the pre-block quiz in the mobile app group compared to the control group (an increase of 0.23 questions vs 1.67, p=0.045). There was a trend of increased improvement in confidence in pediatric critical care knowledge for the App group; however, the difference did not reach statistical significance by Pearson's Chi-square test (p=0.246). Similarly, there was no statistical difference between the two study groups for change in Comfort Level in PICU from the baseline level.Conclusion: Implementation of a service-specific mobile app may enhance residents' clinical experience and improve self-efficacy. Further investigation is warranted.

Aim: (PRIMARY) Assess the changes in bone level (6 and 12 months after implant placement) between the test (definitive abutment (DEF)) and control (healing abutment (HEA)) groups. (SECONDARY) Assess the changes in bone level (6 and 12 months after implant placement) between the 1 mm high abutment group and 2 mm abutment group. Evaluate changes in implant stability recorded with analysis of the resonance frequency (RFA) Osstell system, at 6 and 12 months after implant placement, between the control group (HEA) and test (DEF). For the DEF group, the abutment was placed at the time of the surgery and was never removed. For the HEA group, the abutment was removed three times during the manufacture of the crowns. The abutments used were 1 mm high (Subgroup A) and 2 mm high (Subgroup B). Materials and methods: A total of 147 patients were selected between 54.82 ± 11.92 years old. After implant placement, patients were randomly distributed in the DEF and HEA group. After the implant placement, a periapical radiograph was taken to assess the peri-implant bone level; the same procedure was carried out 6 and 12 months post-placement. To compare the qualitative variables between the groups (HEA/DEF), the Chi-square test was used; for quantitative (MANOVA). Results: After a year, the accumulated bone loss was 0.48 ± 0.71 mm for the HEA group and 0.36 ± 0.79 mm for the DEF group, without statistical significance. Differences were only found due to timing (time) between 0 and 6 months (=0.001) and 0 and 12 months (0.001), with no differences attributable to the study groups (DEF and HEA). The accumulated bone loss (1 year) was 0.45 ± 0.78 mm for the 1 mm abutment group and 0.41 ± 0.70 mm for the 2 mm abutment group (p = 0.02). No differences were observed in implant stability between groups. Conclusions: The “One Abutment—One Time” concept does not reduce peri-implant bone loss compared to the connection–disconnection technique. The height of the abutment does influence bone loss: the higher the abutment, the lower the bone loss.

Objective: To compare the success rate of different obturation procedures in primary mandibular second molars clinically and also by digital radiovisiography. Methods: A total of 40 children aged between 4-8 years with deeply carious mandibular second primary molars indicated for single session pulpectomy were selected. Canals were obturated with Metapex. The 3 study groups (Endodontic plugger, Handheld lentulospiral, Navi Tip syringe) were compared with the control group (reamer) both clinically and radiovisiographically. The data collected were statistically analyzed using Pearson’s Chi-square and Fisher’s exact test. Results: The use of Navi tip syringe led to the least number of voids followed by Endodontic plugger and Reamer and the highest number of voids was reported with Lentulospiral. Navitip presented maximum number of optimally filled cases followed by Endodontic plugger and Lentulospiral and least number of optimally filled cases with reamer. However, there was no statistically significant difference (p>0.05) in any of the groups with clinical (pain and tenderness to percussion) and radiographic parameters (presence or absence of voids and length of obturation). Conclusion: Within the limitations of the present study, though the clinical outcome was statistically insignificant, Navitip syringe exhibited encouraging results and is a promising option for obturation in primary teeth.

Abstract Objective: To analyze the prevalence, distribution, clinical features, and relationship with dental anomalies of maxillary canine impaction. Materials and Methods: The complete pretreatment records of 1674 orthodontic patients were examined. Subjects with maxillary impacted canines were divided into two study groups: a palatally displaced canine (PDC) group (114 patients) and a buccally displaced canine (BDC) group (37 patients). These were compared to a control group of 151 patients who were randomly selected from the initial sample without maxillary canine impaction. The significance of associations between canine impaction and dental and clinical features and anomalies was examined with the chi-square test. Results: PDC patients presented with normal overjet and facial profile and a lower degree of dental arch crowding in comparison to the control patients. PDC patients showed a higher prevalence of impaction of other teeth, dental aplasia, transposition, and peg-shaped maxillary lateral incisors (odds ratios 3.3, 2.6, 8.3, and 5.8, respectively). Conclusion: PDC was frequently the only orthodontic problem of patients. BDC group patients did not present with notable differences in clinical and dental features or dental anomalies compared to control subjects.

Abstract Objectives: To determine the success of bracket retention using an adhesion promoter with and without the additional microabrasion of enamel. Materials and Methods: Fifty-two teeth with severe dental fluorosis were bonded in vivo using a split-mouth design where the enamel surfaces of 26 teeth were microabraded with 50 μm of aluminum silicate for 5 seconds under rubber dam and high volume suction. Thirty-seven percent phosphoric acid was then applied to the enamel, washed and dried, and followed by placement of Scotchbond Multipurpose Plus Bonding Adhesive. Finally, precoated 3M Unitek Victory brackets were placed and light cured. The remaining teeth were bonded using the same protocol but without microabrasion. Results: After 9 months of intraoral service, only one bond failure occurred in the control group where microabrasion was used. Chi-square analysis revealed P = .31, indicating no statistical significance between the two groups. Conclusions: Bonding orthodontic attachments to fluorosed enamel using an adhesion promoter is a viable clinical procedure that does not require the additional micro-mechanical abrasion step.

ABSTRACT Objective: To evaluate the effects of Dramatic Therapeutic Play (DTP) technique on the degree of anxiety in hospitalized school-age children. Method: Randomized clinical trial performed in two hospitals ofSão Paulo, between May and October 2015. The intervention consisted of the application of DTP and the outcome was evaluated through the Child Drawing: Hospital (CD: H) instrument. The Wilcoxon-Mann Whitney, Corrected t, Fisher’s exact and Chi-square tests were used in the analysis. Statistical significance was set at 5%. Results: In all, 28 children participated in the study. The majority of children (75%) had a low anxiety score, with a mean CD: H score of 73.9 and 69.4 in the intervention and control groups respectively, and with no significant difference. Conclusion: Children submitted to DTP had the same degree of anxiety as those in the control group. However, it is suggested that new studies be performed with a larger number of children in different hospitalization scenarios.

This study sought to discourse whether an experimental methodology could provide instruction in identification and quantitation tasks which were categorized as intellectual skills with some motor skill components. Hypotheses were derived from the thesis that remotely located students would perform at a level equal to or higher than conventionally trained counterparts. Subjects participating in the study were medical laboratory workers from four states. A remote delivery instructional methodology was compared with conventional instruction. Conventional instruction and the experimental methodology essentially differed only in that in the experimental methodology subjects were remotely located from instructors. Terminal Learning Objective tests were scored on a pass/fail basis. A Chi-square one sample test yielded a value below that required for statistical significance. There was no evidence to suggest that failures signified anything other than random processes or other sources of variation not inherent in administration of instruction. The conclusion reached is that the experimental treatment is no different in effect than the control group treatment. A discussion of potential cost savings using teleconferencing is presented.

Aim. To determine the risk factors for xerostomia.Methods. The study included 137 patients aged 25 to 60 years (61 males, 76 females), the main group consisted of 40 patients with xerostomia (11 males, 29 females), with a median age of 44.5 years (38; 49.5). The control group included 97 patients without xerostomia (50 males, 47 females), median age - 42 years (36; 49). The questionnaire by V.V. Afanas’ev (1993) was used to collect the complaints, anamnesis and to determine the risk factors for xerostomia. Qualitative indicators are listed as absolute numbers and shares (%). In assessing the statistical significance of qualitative indicators differences, contingency tables with subsequent Pearson chi-square test were used.Results. Among the patients of the main group, 19 (47.5%) took medications decreasing the salivation, with intake period duration ranging from 1 to 4 months. When questioned, patients with xerostomia reported statistically significant increase in the rates of cardiovascular disorders (15 patients, 37.5%), gastrointestinal tract diseases (11 patients, 27.5%), endocrine diseases (10 patients, 25%), musculoskeletal diseases (9 patients, 22.5%). The combination of three or more positive answers on V.V. Afanas’ev questionnaire questions was revealed in 12 (30%) patients of the main group, which was significantly higher compared to the control group (1 patient, 1.03%).Conclusion. The most typical reasons for developing xerostomia were the following: taking medications decreasing the salivation, presence of cardiovascular, gastrointestinal, musculoskeletal and endocrine disorders. Three or more positive answers on V.V. Afanas’ev questionnaire questions increase the probability of detecting xerostomia in a respondent.

Cortisol Levels

Delivery, induction, stimulation, cesarean section with the aid of a vacuum extraction, for example, can reduce maternal confidence on the smooth delivery process, as well as improve postpartum stress. These stressors stimulate the HPA axis (hypothalamus-pituitary-adrenal), so that the adrenal cortex produces more cortisol hormone, it can increase postpartum blues. The objective of this study was to analyze the effect of delivery stimulation on protracted labor on cortisol levels and the occurrence of postpartum baby blues. This was an experimental study of non-randomized post-test control group. The subject of the study 30 patients in labor taken consecutive sampling, divided into 2 groups (normal delivery and stimulation) each group consist of 15 patients. In stimulation delivery group, it is examined of cortisol serum levels after five days and then continued for postpartum blues occurrence measurement. Statistical analysis using t-test for differences in levels of cortisol and chi square for analyzing the effect on the occurrence of post-partum blues (a=0.05). Mean  level of cortisol in delivery stimulation group is 40.29 ± 5.58, in normal delivery is 33.59 ± 11.17, with p=0.047, meaning there are significant differences both study groups. Stimulation delivery increases the occurrence of post-partum blues 5.50 times compared to normal delivery (OR=5.50 and p=0.028). Mean cortisol levels on post-partum blues higher at 42.90 ± 6.97 compared to no post-partum blues 30.14 ± 6.66, p=0:00, which means there are significant differences both groups. In conclusion, there was significant relationship between stimulation in protrated labor that increases cortisol serum level and post partum blues incidence.

Induction of general anesthesia with propofol and fentanyl could result in hypotension and bradycardia. Various methods are being used to prevent these adverse effects. The aim of our study was to assess the efficacy and safety of a small dose of ephedrine in prevention of hypotension following administration of propofol and fentanyl. This prospective, randomized, comparative study was conducted among a total of 50 patients, both genders, age 18 years up to 60 years with ASA grade Ι and ΙΙ and some of class ΙΙΙ, presented for elective surgery under general anesthesia. Patients were randomly allocated into one of two groups (25 patients in each): CG (the control group), which received propofol in a dose of 2 mg/kg, intravenously, over 20–30 s mixed with 2 mL normal saline: and EphG (Ephedrine group), while received propofol in a dose of 2 mg/kg, intravenously, over 20–30 s mixed with 2 mL of ephedrine (10 mg). The Mean Arterial Blood Pressure (MAP) and Heart Rate (HR) were recorded before induction and then every 1 min up to 6 min after induction. The categorical data are presented as a number and percentage and were subjected to Fisher’s exact or Chi-square test for analysis. The statistical significance was p≤0.05. The significant differences in HR were observed in the 3rd,4th, and 5th minutes with P-value, 0.018, 0.000, 0.000, respectively. However, no patient in the study participants had bradycardia. The significant differences in MAP were observed in the 2nd, 3rd,4th, and 5th minutes with P-value, 0.035, 0.000, 0.000, and 0.000, respectively. The percentage of patient in CG who developed hypotension in the 3rd and 4th is 44% and 32% compared to 8% and 0% in EphG, with significant differences (P-value 0.004 and 0.002, respectively). Administration of small dose of ephedrine with propofol could attenuate propofol/fentanyl hypotensive and bradycardic effects.
