INTRODUCTIONThis study evaluated the efficacy of tinnitus retraining therapy (TRT) in habituating patients with tinnitus.

MATERIALS AND METHODSThis is a retrospective review of patients who underwent TRT in a tertiary referral Otorhinolaryngology unit. Patients were followed up with structured interviews with the aid of questionnaire forms. Habituation following TRT was evaluated.

RESULTSA total of 702 patients were included (55% male, 45% female). Habituation of reaction to tinnitus and habituation of perception were analysed. Average duration of follow up was 33 months. In total, 68% of patients described improvement in annoyance following TRT. Of these patients, 80% of them described habituation of perception as well. There was no statistical difference in gender and age between patients who did and did not respond to TRT. However, duration of treatment was significantly longer in patients who habituated (P <0.05). Patients who adopted treatment strategies recommended based on Jastreboff's TRT categories were also found to have higher success rates compared to those who refused.

CONCLUSIONThe goal of TRT is to achieve habituation of reaction to tinnitus. Habituation of perception is often a secondary result of sufficiently habituated response. From our study, more than two thirds of patients with tinnitus achieved habituation of reaction and of these, the majority also habituated to awareness of the tinnitus.

Purpose: This study aimed to evaluate the effectiveness of an interactive virtual reality (VR) play intervention including instructional play and emotional catharsis play sessions in reducing children's pain and fear during intravenous placement. Methods: A randomized controlled trial with parallel groups was conducted. The sample consisted of 134 hospitalized children aged 6–12 years (intervention group: n = 69; comparison group: n = 65). The intervention involved one immersive intravenous scene in VR before the actual intravenous placement and one emotional catharsis VR play after injection. The comparison group received an educational photo book about intravenous placement before receiving intravenous placement. The children and their caregivers rated their pain and fear by using the Wong–Baker FACES Pain Rating Scale and the Children's Fear Scale. The time required for successful intravenous insertion was also compared between the two groups. Results: Children's pain (p = .028) and fear scores (p = .004) were significantly lower in the intervention group than in the comparison group. Their caregivers' pain and fear scores (both p < .001) were significantly lower in the intervention group. The time required for successful intravenous insertion did not differ significantly between the intervention and comparison groups. Conclusions The interactive play intervention with VR effectively reduced children's levels of pain and fear during the intravenous placement procedure. The results of this study can serve as a reference for the implementation of a feasible, child-friendly care practice for clinical intravenous placement in school-aged children.

INTRODUCTIONTo determine the seroepidemiology of dengue virus infection in a representative sample of the adult resident population aged 18 years old to 74 years old in Singapore and to estimate the proportion of asymptomatic dengue infection during the 2004 epidemic.

MATERIALS AND METHODSThe study was based on 4152 stored blood samples collected between September and December 2004 from participants aged 18 years old to 74 years old during the 2004 National Health Survey. Sera were tested for IgG and IgM antibodies using a commercial test kit (PanBio Capture/Indirect ELISA).

RESULTSOf the study population, 59.0% and 2.6% tested positive for dengue IgG (past infection) and IgM/high-titre IgG (recent infection), respectively. Only 17.2% of young adults aged 18 years old to 24 years old were dengue IgG positive. Multivariate analyses showed that older age, Indian ethnicity and male gender were significantly associated with past infection, whereas only age was significantly associated with recent dengue infection. Based on the dengue cases notified during the period of survey, it was estimated that for every 23 individuals recently infected with dengue, only 1 was reported to the health authority as a clinical case.

CONCLUSIONThe Singapore population is highly susceptible to dengue epidemics despite its aggressive Aedes prevention and control programme. The finding of a high proportion of unreported cases due to asymptomatic and subclinical infection poses a challenge for dengue control.

ABSTRACT Orofacial odontogenic infection, although arises from dental origin, can extend into the facial spaces and lead to debilitating complications. This study analysed the clinical pattern and management of orofacial odontogenic infection in a tertiary hospital namely Hospital Raja Permaisuri Bainun in Perak, Malaysia. We investigated any associations between socio-demographic factors, diabetic, comorbidities, smoking, pregnancy, antibiotic resistance, number and type of space infected towards prolonged hospital stay. All adult patients with orofacial odontogenic infections treated by Department of Oral and Maxillofacial Surgery from 2014 to 2018 were included. Clinical patterns were evaluated. Statistical analysis was performed to measure various variables towards prolonged hospital stay. A total of 154 patients (78 male, 76 female) were included in this study with mean age of 37.95 ± 14.9 years. Key factors of orofacial odontogenic infection requiring admissions were swelling, pain, trismus, odynophagia, reduced oral intake, raised floor of mouth and dyspnea. Among inpatients, three factors were significantly associated with prolonged hospital stay, namely antibiotic resistance, multiple space and secondary space infection. Local prevalence data was reported. Pus culture and sensitivity tests were recommended for all inpatients with multiple space and secondary space involvement, in order to rule out antibiotic resistance and to improve recovery rate.

Transvenous implantable cardioverter defibrillators are a type of implantable cardiac device. They are effective at reducing total and arrhythmic mortality in patients at risk of sudden cardiac death. Subcutaneous implantable cardioverter defibrillators (S-ICDs) are a new alternative that avoids the disadvantages of transvenous lead placement. In this case series, we report on the initial feasibility and safety of S-ICD implantation in Singapore.

INTRODUCTIONThe use of non-fluoroscopic systems (NFS) to guide radiofrequency catheter ablation (RFCA) for the treatment of supraventricular tachycardia (SVT) is associated with lower radiation exposure. This study aimed to determine if NFS reduces fluoroscopy time, radiation dose and procedure time.

METHODSWe prospectively enrolled patients undergoing RFCA for SVT. NFS included EnSiteTM NavXTM or CARTO® mapping. We compared procedure and fluoroscopy times, and radiation exposure between NFS and conventional fluoroscopy (CF) cohorts. Procedural success, complications and one-year success rates were reported.

RESULTSA total of 200 patients over 27 months were included and RFCA was guided by NFS for 79 patients; those with atrioventricular nodal reentrant tachycardia (AVNRT), left-sided atrioventricular reentrant tachycardia (AVRT) and right-sided AVRT were included (n = 101, 63 and 36, respectively). Fluoroscopy times were significantly lower with NFS than with CF (10.8 ± 11.1 minutes vs. 32.0 ± 27.5 minutes; p < 0.001). The mean fluoroscopic dose area product was also significantly reduced with NFS (NSF: 5,382 ± 5,768 mGy*cm2 vs. CF: 21,070 ± 23,311 mGy*cm2; p < 0.001); for all SVT subtypes. There was no significant reduction in procedure time, except for left-sided AVRT ablation (NFS: 79.2 minutes vs. CF: 116.4 minutes; p = 0.001). Procedural success rates were comparable (NFS: 97.5% vs. CF: 98.3%) and at one-year follow-up, there was no significant difference in the recurrence rates (NFS: 5.2% vs. CF: 4.2%). No clinically significant complications were observed in both groups.

CONCLUSIONThe use of NFS for RFCA for SVT is safe, with significantly reduced radiation dose and fluoroscopy time.

INTRODUCTIONRemote monitoring of cardiac implantable electronic devices (CIED) has been shown to improve patient safety and reduce in-office visits. We report our experience with remote monitoring via the Medtronic CareLink(®) network.

METHODSPatients were followed up for six months with scheduled monthly remote monitoring transmissions in addition to routine in-office checks. The efficacy of remote monitoring was evaluated by recording compliance to transmissions, number of device alerts requiring intervention and time from transmission to review. Questionnaires were administered to evaluate the experiences of patients, physicians and medical technicians.

RESULTSA total of 57 patients were enrolled; 16 (28.1%) had permanent pacemakers, 34 (59.6%) had implantable cardioverter defibrillators and 7 (12.3%) had cardiac resynchronisation therapy defibrillators. Overall, of 334 remote transmissions scheduled, 73.7% were on time, 14.5% were overdue and 11.8% were missed. 84.6% of wireless transmissions were on time, compared to 53.8% of non-wireless transmissions. Among all transmissions, 4.4% contained alerts for which physicians were informed and only 1.8% required intervention. 98.6% of remote transmissions were reviewed by the second working day. 73.2% of patients preferred remote monitoring. Physicians agreed that remote transmissions provided information equivalent to in-office checks 97.1% of the time. 77.8% of medical technicians felt that remote monitoring would help the hospital improve patient management. No adverse events were reported.

CONCLUSIONRemote monitoring of CIED is safe and feasible. It has possible benefits to patient safety through earlier detection of arrhythmias or device malfunction, permitting earlier intervention. Wireless remote monitoring, in particular, may improve compliance to device monitoring. Patients may prefer remote monitoring due to possible improvements in quality of life.
