METHODS: Fifty-five cases of CCTA were collected retrospectively and all images including reformatted axial images at systolic and diastolic phases as well as images with curved multi planar reformation (cMPR) were obtained. Quantitative image quality including signal intensity, image noise, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) of right coronary artery (RCA), left anterior descending artery (LAD), left circumflex artery (LCx) and left main artery (LM) were quantified using Analyze 12.0 software.
RESULTS: Six hundred and fifty-seven coronary arteries were evaluated. There were no significant differences in any quantitative image quality parameters between genders. 100 kilovoltage peak (kVp) scanning protocol produced images with significantly higher signal intensity compared to 120 kVp scanning protocol (P<0.001) in all coronary arteries in all types of images. Higher SNR was also observed in 100 kVp scan protocol in all coronary arteries except in LCx where 120 kVp showed better SNR than 100 kVp.
CONCLUSIONS: There were no significant differences in image quality of CCTA between genders and different tube voltages. Lower tube voltage (100 kVp) scanning protocol is recommended in clinical practice to reduce the radiation dose to patient.
OBJECTIVE: To estimate the prevalence of postpartum dyspareunia.
SEARCH STRATEGY: Web of Science, Scopus, PubMed, and Embase databases were searched to July 2019 using keywords including 'perineal pain,' 'dyspareunia,' and 'sexual pain'.
SELECTION CRITERIA: Observational studies on the prevalence of postpartum dyspareunia were included.
DATA COLLECTION AND ANALYSIS: Two authors independently reviewed articles and extracted data. Study heterogeneity was evaluated by I2 index; publication bias by Egger and Begg tests.
MAIN RESULTS: Twenty-two studies enrolling 11 457 women were included. Based on meta-analysis, the overall estimated prevalence of dyspareunia was 35% (95% confidence interval [CI], 29%-41%). The prevalence was 42% (95% CI, 26%-60%) at 2 months, 43% (95% CI, 36%-50%) at 2-6 months, and 22% (95% CI, 15%-29%) at 6-12 months postpartum. Begg test showed no significant bias in data related to the prevalence of postpartum dyspareunia (p = 0.466).
CONCLUSION: The prevalence of postpartum dyspareunia was 35% and decreased with increasing postpartum duration. Given the high prevalence and its impact on a woman's quality of life, special attention should be paid to this common complaint during the postpartum period.
DESIGN: Single-centre prospective two-arm parallel randomised controlled trial.
SETTING: Orthodontic Clinic, Faculty of Dentistry, Universiti Teknologi MARA, Selangor, Malaysia.
PARTICIPANTS: Adult orthodontic patients aged 18-35 years, indicated for DPT and LC, who were fit and healthy with a body mass index of 18.5-25.0, not contraindicated to radiographic examination, not pregnant, and did not have a history of facial or skeletal abnormalities or bone diseases were included.
METHODS: Thirty-eight adult orthodontic patients were randomised into control and intervention groups. DPT and LC radiographs in the control group were obtained using standard scanning parameters as prescribed by the manufacturer using Orthopantomograph® OP300 by Instrumentarium. Scanning parameters in the intervention group were reduced by 60% for DPT (60 kV, 3.2 mA) and 30% for LC (85 kV, 8 mA). A five-point rating scale was used for the assessment of image quality. Images were evaluated for diagnostic performance by detection of anatomical landmarks. Mann-Whitney test was performed to compare the quality and diagnostic performance of the images and the observer agreement was assessed using the intraclass correlation coefficient (ICC).
RESULTS: For image quality, the control group produced slightly lower median scores (DPT 2.0, LC 2.0) compared to the intervention group (DPT 2.0, LC 3.0). For diagnostic performance, both groups showed similar median scores (DPT 21.0, LC 32.0). The differences between control and intervention groups for both modalities were not statistically significant. The average scores for intra-observer agreement were excellent (ICC 0.917) and inter-observer agreement was good (ICC 0.822).
CONCLUSION: Minimising radiation exposure by reducing scanning parameters on digital DPT by 60% and LC by 30% on Intsrumentarium 300 OP did not affect the quality and diagnostic performance of the images. Thus, scanning parameters on digital DPT and LC should be reduced when taking radiographs.
METHODS: A randomized, parallel group, double blinded study was conducted on 54 patients undergoing orthodontic treatment at a university clinic. They were randomized to 3 groups, i.e., WhatsApp (W) group, electronic mail (email) (E) group and control (C) group with 18 subjects in each group. Group (W) and group (E) received oral health messages once a week through WhatsApp and email reminders, respectively, while group (C) did not receive any reminders. Plaque was measured at baseline (T0), after 4 weeks (T1), and after 8 weeks (T2). For each subject, intraoral photographs were taken after application of a plaque-disclosing agent; and the area covered by plaque was measured on teeth 12, 13, 43, 22, 23 and 33 by planimetry. Data were analyzed using SPSS (version 22, IBM Corp., Armonk, NY, USA). Mixed analysis of variance (ANOVA) was used to compare plaque scores between and within the groups.
RESULTS: A total of 54 subjects (14 males and 40 females) with mean age of 22.43 years completed the study. At the end of 8 weeks, no statistically significant difference in the mean plaque score was found between the groups at the different time intervals (p = 0.201).
CONCLUSION: WhatsApp and email reminders did not significantly influence the oral hygiene compliance of orthodontic patients.
METHOD: Thirty patients with single or multiple fractures were selected purposively for descriptive survey study between January 2018 to December 2018. Their ages varied from 41 to 80 years. There were 26 female and four males. 24 patients have single fracture and six had multiple fractures following low impact trauma. The demographic parameters were studied by structured interview schedule, and the research variable, the risk factors were studied by interview, biophysical assessment and records of BMD value through DEXA and serum level of vitamin D. Socio-demographic variables like age, sex, body weight, Body mass index (BMI), etc. were selected and their relationship were assessed to find out the risk factors of fragility fractures in society by research variables like risk factors of osteoporotic fractures. For statistical analysis of determination of association between such factors and fragility fractures, non-parametric Fisher exact test and Odds ratio was used.
RESULTS: In our study, osteoporotic fractures occurred majority (86.66%) among female maximally among 60-69 years age group. Whereas in relatively younger age (40-60 years), abnormal BMI (low or high) is responsible for fragility fracture as 46.6% of such fractures occurred in this group as 20% fracture are associated with underweight and 40.66% with overweight BMI. Tobacco smoking increases the risk of fragility fractures twice (as relative risk ratio 2) and rheumatoid arthritis increases the six-fold (as relative risk ratio 6). All 100% had history of fall. Level of serum vitamin D, low DEXA scan value (less than -2.5) and fall on ground resulting in low impact injuries shows strong association between those and fragility fractures. On the other hand, all the risk factors remain same for the recent and old fractures.
CONCLUSION: Several risk factors need to be addressed properly apart from medical managements to reduce the risk of occurrence of osteoporotic fractures.
