Frequency reallocation based on cochlear place frequencies in cochlear implants: a pilot study

Abstract Purpose The aim of this study is to evaluate speech perception outcomes after a frequency reallocation performed through the creation of an anatomically based map obtained with Otoplan®, a tablet-based software that allows the cochlear duct length to be calculated starting from CT images. Methods Ten postlingually deafened patients who underwent cochlear implantation with MED-EL company devices from 2015 to 2019 in the Tertiary referral center University Hospital of Verona have been included in a retrospective study. The postoperative CT scans were evaluated with Otoplan®; the position of the intracochlear electrodes was obtained, an anatomical mapping was carried out and then it was submitted to the patients. All patients underwent pure tonal and speech audiometry before and after the reallocation and the audiological results were processed considering the Speech Recognition Threshold (SRT), the Speech Awareness Threshold (SAT) and the Pure Tone Average (PTA). The differences in the PTA, SAT and SRT values before and after the reallocation were determined. The results were statistically processed using the software Stata with a significance value of α < 0.05. Results The mean values of SRT (61.25 dB versus 51.25 dB) and SAT (49 dB versus 41 dB) were significantly lower (p: 0.02 and p: 0.04, respectively) after the reallocation. No significant difference was found between PTA values (41.5 dB versus 39.25 dB; p: 0.18). Conclusions Our preliminary results demonstrate better speech discrimination and rapid adaptation in implanted postlingually deaf patients after anatomic mapping and subsequent frequency reallocation.

Removal Technique

This study evaluated the influence of apical patency, root filling removal technique and cleaning of the apical foramen, concerning the amount of debris extruded during root canal retreatment. Forty mandibular incisors were randomly assigned to 4 groups - GIM (n=10), GIIM (n=10), GIPT (n=10) and GIIPT (n=10), which were named according to leaving (I) or not (II) apical patency during canal preparation and filling removal technique (manual - M or ProTaper system - PT). After filling material removal, each specimen of each group had the apical foramen cleaned by sizes 15, 20 and 25 instruments, generating 12 subgroups: GIM15, GIM20, GIM25, GIIM15, GIIM20, GIIM25, GIPT15, GIPT20, GIPT25, GIIPT15, GIIPT20 and GIIPT25. Extruded filling debris was collected by a Milipore filtration system, an HV-durapore, 0.45 µm pore filter with a 25 mm diameter. The filters were weighed before and after the collection on an analytical scale (10–5 g), and the difference was calculated. The mean weight of extruded filling debris was analyzed statistically by Kruskal-Wallis and Friedman ANOVA tests (α=0.05). The mean values found in the groups (in mg) were: GIM (0.95±0.94), GIIM (0.47±0.62), GIPT (0.30±0.31) and GIIPT (0.32±0.44). There was no statistically significant difference among any of the groups or subgroups (p>0.05). ProTaper provided the smallest amount of extruded filling material, regardless of presence or absence of apical patency, followed by manual technique, without and with apical patency. Additional amounts of debris were collected during cleaning of the apical foramen, regardless of the instrument, presence/absence of patency or root filling removal technique.

Introduction: Limits of movement in knees is one of the most common complications following trauma and surgery. With early diagnosis and appropriate treatment choices, knee replacement and performance improvement are expected in many patients. However, limits of movement in knees is unpleasant and should be corrected as soon as possible. In this study, we decided to evaluate the results of arthroscopic release in motion limits of knees. Methods: This was a descriptive cross-sectional study.14 patients who referred to the Shahid Sadoughi Hospital of Yazd from 2014 to 2016 and diagnosed with knee limitation (flexion or extension restriction of more than 10 degrees) were selected. Patients were undergone arthroscopic release and followed-up for 6 months. Lysholm knee score, degrees of flexion and extension, and patient satisfaction were evaluated. The results were analyzed by SPSS-18 and statistical tests Paired T-test as well as Spearman correlation. Results: The mean age of the patients was 28.92±10.99 years. The most common type of trauma in the patients was femoral distal fracture (46.7%). The frequency of the patients' satisfaction with arthroscopy was as followed: 50% (7 patients), had moderate satisfaction, 28.6% (4 ones), high satisfaction, and 21.4% (3 ones) had low satisfaction.The mean difference in Lysholm Knee Score, improvement in degree of extension, improvement in degree of flexion and pain score before and after arthroscopy were 26.21±14.11,64.78±26.13,3.57±2.92 and 4.13±1.65,respectively.There was a significant difference between the mean values of these factors before and after arthroscopy. Conclusion: According to the results obtained, we can conclude that arthroscopic release is an effective and low-complication method in motion limits of knees.

Background: To date, FM using middle ear packing has rarely reported. In this study, we hypothesized that middle ear packing with dexamethasone soaked gelfoam and fibrin glue over the fat graft could promote the success rate of TMP closure regardless of perforation size. Methods: Between January 2005 and July 2020, a total of 209 patients who underwent fat myringoplasty due to chronic TMP at tertiary referral center were encountered and analyzed. The success rate and audiologic outcome was analyzed. Results: The mean successful TM closure rate was 88.0 %. The success rate by different age generation was not significant difference. The size of the perforation grade showed no significant difference. The perforation site by anterior or posterior was not significant. The preoperative mean threshold of AC, BC and ABG were 55.71, 12.98 and 42.73 dB respectively. The postoperative mean threshold of AC, BC and ABG were 23.67, 12.98 and 10.69 dB. The change of preoperative and postoperative hearing showed statistically significant. Conclusion: From our results, the simple trimming of the perforation edge and middle ear packing with external ear canal packing using fibrin glue induced the stable adhesion between the remnant TM and the fat graft.

Abstract Background Establishment and improvement of patients’ trust in healthcare organizations like hospitals necessitate delivery of high-quality services by nurses, as the largest group of healthcare providers. The present study aimed to compare hospital service quality based on the HEALTHQUAL model and trusting nurses at university and non-university hospitals in Iran. Methods This comparative cross-sectional study was conducted on 990 patients admitted to university and non-university hospitals located in Bushehr Province, southern Iran, who were selected using the stratified random sampling method. The data were collected through the HEALTHQUAL questionnaire and the Trust in Nurses Scale, and then analyzed via the SPSS Statistics software (version 22) as well as the General Linear Model (GLM) univariate procedure and the Chi-square test with a significance level of 0.05. Results The study findings revealed that the mean values of real quality (perceptions) and ideal quality (expectations) were 3.89 ± 0.69 and 4.55 ± 0.47, respectively. The gap between the real and ideal quality (− 0.64) was also larger at non-university hospitals from the patients’ viewpoints. Comparing various dimensions of service quality, the largest gap at university and non-university hospitals was associated with “environment” (− 0.13) and “empathy” (− 0.18), respectively. Additionally, the mean scores of the patient trust in nurses at university and non-university hospitals were 10.34 ± 5.81 and 8.71 ± 4.05, respectively, being a statistically significant difference (p < 0.001). Conclusion The study results demonstrated that hospital service quality and trusting in nurses were at higher levels at the university hospital than the non-university one; however, hospital service quality was at a lower level than what the patients had expected. Accordingly, hospital managers and policy-makers were suggested to focus on patients to reduce gaps in service quality, to promote service quality, and to provide better healthcare services to patients.

Mechanical Cleaning

Introduction: The full decontamination and disinfection of the root canal system is essential for the success of regenerative endodontic procedures. The current literature does not have information regarding mechanical cleaning of immature teeth with contemporary endodontic instuments. Aim: To compare the thickness and volume of the dentin removed from the roots of immature teeth after endodontic preparation using XP-endo Finisher, GentleFile Brush and a standard H-file scraping technique through micro-computed tomography. Methods: The study included 51 immature permanent molars. Endodontic access was prepared and without performing preliminary extirpation of the pulp, the teeth were divided into three groups. The first group of teeth were instrumented for two minutes with XP-endo Finisher, the second - two minutes with Gentlefile Brush, in the third group the root canals walls were scraped with a No. 40 H-file. The thickness and the volume of the removed dentin was assessed using micro-CT imaging before and after the use of the instruments. Results: There is no statistically significant difference in the mean values of thickness of dentin removed between the teeth, prepared with XP-endo finisher and Gentlefile Brush. When comparing the mean values of volume of dentin removed between the separate groups, a statistically significant difference was discovered for every compared pair with the highest volume of removed dentin in the group prepared with a hand instrument. Conclusion: The endodontic systems tested when used in immature permanent teeth remove significantly less quantity of hard dental structures compared to a hand file for scraping the root canal.

ObjectiveLimited data from pharmacokinetic studies in underweight and severely malnourished children have indicated an impaired activity of their hepatic enzymes. We used the caffeine breath test to assess the metabolising activity of cytochrome P450 1A2 (CYP1A2) enzyme in underweight children.MethodsUnderweight children from the paediatric outpatient clinic, Lagos State University Teaching Hospital, Ikeja in Nigeria, were studied. After an overnight fast, 15 underweight children took 3 mg/kg labelled caffeine orally. Breath samples were collected in duplicate at −20, −10 and −1 min and at 15 min intervals for 2 h. The mean cumulative per cent dose recovered (CPDR) of labelled caffeine in the expired carbon dioxide was determined over the study period. This was repeated after 2–6 weeks of nutritional rehabilitation.ResultsThe mean areas under the enrichment-time curve before and after nutritional rehabilitation were 0.539±0.320 and 0.620±0.322 atom per cent excess minute, respectively. The difference between the two values was not statistically significant (p=0.528). The mean CPDR in the exhaled carbon dioxide of the underweight children over a period of 2 h was 7.56±4.01% and 7.95±3.68% before and after nutritional rehabilitation, respectively, and there was no significant difference in the mean values (p=0.603).ConclusionsThe metabolism of caffeine was not significantly affected in underweight children compared with after 2–6 weeks of nutritional rehabilitation. This suggests that hepatic CYP1A2-metabolising activity was not significantly impaired in underweight children.

Chemotherapy shows high effectiveness, but also has side effects, including mucositis. Mucositis can cause pain, difficulty sleeping, eating disorders, mood, and activity, which has implications for the quality of life of children. The purpose of this study was to identify the incidence of mucositis and the factors that influence the incidence of mucositis in cancerous children receiving chemotherapy treatment. This research method is descriptive correlational analysis with cross sectional design. Consecutive sampling technique was used to establish respondents as research samples so as to get 60 respondents. Data were analyzed univariately and bivariately. Bivariate analysis was performed with Chi square test and 2 mean difference test to see differences in the mean values of mucositis before and after chemotherapy. The results showed that almost all cancer children who received chemotherapy had 53 people (88.3%) and a small portion, 7 people (11.7%) had no mucositis. There was a significant difference in the mean value (p = 0,000) between before and after chemotherapy with an increase in the average mucositis value of 3.12. The research shows that there is a significant relationship (p <0.05) between previous mucositis experience (p = 0,000), type of cancer (p = 0.025), type of chemotherapy (p = 0.010), and duration of therapy (p = 0.027) and the incidence of mucositis. Meanwhile nutritional status was not related to the incidence of mucositis (p = 0.077). Nurses, as health workers who most often contact with patients, should be able to improve nursing care in cancer children who get chemotherapy in minimizing the occurrence of mucositis by conducting routine mucositis and oral care assessments.

Purpose To examine changes in parameters of the visual field test before and after blepharoptosis surgery in patients with glaucoma. Methods Twenty-three eyes of 14 glaucoma patients who underwent blepharoptosis surgery at Toyama University Hospital between July 2015 and September 2020 were included in this study. Pre- and post-operative values for the mean deviation (MD), pattern standard deviation (PSD) and total deviation (TD) of the upper or lower hemi-visual field in the Humphrey visual field test, best-corrected visual acuity (BCVA), intraocular pressure (IOP), and margin reflex distance (MRD)-1 were compared. Results MRD-1 showed a significant improvement after blepharoptosis surgery (preoperative MRD-1: 1.0 ± 0.82 mm, postoperative MRD-1: 3.26 ± 0.66 mm, p < 0.001). There were no significant differences in BCVA, IOP, MD and PSD values before and after surgery. On the other hand, there was a significant improvement in the superior TD (preoperative: −11.29 ± 6.57 dB, postoperative: −9.88 ± 7.31 dB, p = 0.044) although no significant difference was detected in the inferior TD postoperatively. The preoperative parameters of 2 groups (improvement and non-improvement groups of postoperative superior TD) were compared. Preoperative MD and superior TD were significantly lower in the improvement group (p = 0.03, p = 0.004, respectively), although there was no significant difference in preoperative PSD and inferior TD between the two groups. Conclusion In glaucoma patients, blepharoptosis may interfere with accurate visual field assessment, especially of superior TD.
