BackgroundMandibular reconstruction is conventionally performed freehand, CAD/CAM-assisted, or by using partially adjustable resection aids. CAD/CAM-assisted reconstructions are usually done in cooperation with osteosynthesis manufacturers, which entails additional costs and longer lead time. The purpose of this study is to analyze an in-house, open-source software-based solution for virtual planning.Methods and MaterialsAll consecutive cases between January 2019 and April 2021 that underwent in-house, software-based (Blender) mandibular reconstruction with a free fibula flap (FFF) were included in this cross-sectional study. The pre- and postoperative Digital Imaging and Com munications in Medicine (DICOM) data were converted to standard tessellation language (STL) files. In addition to documenting general information (sex, age, indication for surgery, extent of resection, number of segments, duration of surgery, and ischemia time), conventional measurements and three-dimensional analysis methods (root mean square error [RMSE], mean surface distance [MSD], and Hausdorff distance [HD]) were used.ResultsTwenty consecutive cases were enrolled. Three-dimensional analysis of preoperative and virtually planned neomandibula models was associated with a median RMSE of 1.4 (0.4–7.2), MSD of 0.3 (-0.1–2.9), and HD of 0.7 (0.1–3.1). Three-dimensional comparison of preoperative and postoperative models showed a median RMSE of 2.2 (1.5–11.1), MSD of 0.5 (-0.6–6.1), and HD of 1.5 (1.1–6.5) and the differences were significantly different for RMSE (p < 0.001) and HD (p < 0.001). The difference was not significantly different for MSD (p = 0.554). Three-dimensional analysis of virtual and postoperative models had a median RMSE of 2.3 (1.3–10.7), MSD of -0.1 (-1.0–5.6), and HD of 1.7 (0.1–5.9).ConclusionsOpen-source software-based in-house planning is a feasible, inexpensive, and fast method that enables accurate reconstructions. Additionally, it is excellent for teaching purposes.

Provision Of Care

Person-centered maternity care (PCMC) is defined as care which is respectful of and responsive to women’s and families’ preferences, needs, and values. In this cross-sectional study we aimed to evaluate the correlations among the degree of PCMC implementation, key indicators of provision of care, and women’s satisfaction with maternity care in Sri Lanka. Degree of PCMC implementation was assessed using a validated questionnaire. Provision of good key practices was measured with the World Health Organization (WHO) Bologna Score, whose items include: 1) companionship in childbirth; 2) use of partogram; 3) absence of labor stimulation; 4) childbirth in non-supine position; 5) skin-to-skin contact. Women’s overall satisfaction was assessed on a 1–10 Likert scale. Among 400 women giving birth vaginally, 207 (51.8%) had at least one clinical risk factor and 52 (13.0%) at least one complication. The PCMC implementation mean score was 42.3 (95%CI 41.3–43.4), out of a maximum score of 90. Overall, while 367 (91.8%) women were monitored with a partogram, and 293 (73.3%) delivered non-supine, only 19 (4.8%) did not receive labour stimulation, only 38 (9.5%) had a companion at childbirth, and 165 (41.3%) had skin-to-skin contact immediately after birth. The median total satisfaction score was 7 (IQR 5–9). PCMC implementation had a moderate correlation with women’s satisfaction (r = 0.58), while Bologna score had a very low correlation both with satisfaction (r = 0.12), and PCMC (r = 0.20). Factors significantly associated with higher PCMC score were number of pregnancies (p = 0.015), ethnicity (p<0.001), presence of a companion at childbirth (p = 0.037); absence of labor stimulation (p = 0.019); delivery in non-supine position (p = 0.016); and skin-to-skin contact (p = 0.005). Study findings indicate evidence of poor-quality care across several domains of mistreatment in childbirth in Sri Lanka. In addition, patient satisfaction as an indicator of quality care is inadequate to inform health systems reform.

Abstract Purpose: To describe the variables that may be utilized in the optimization of three dimensional heads up surgeries (3D-HUS) for achieving better ergonomics among ophthalmic surgeons. Methods: A cross-sectional study conducted at the operating room of a tertiary eye care centre, equipped with ARTEVO 800 3D surgical microscope and display monitor. The parameters noted were: monitor height (MH), surgeon eye to floor distance (ETFD) surgeon eye to monitor distance (ETMD) (Fig. 1a) and viewing tilt (VT) angle. The neck and eye strain of the surgeon and assistant were scored as per Borg’s CR-10 scale, before and after surgeries.Results: 15 surgeries were analysed. The minimum ETMD was 51 inches and eye strain reduced with shorted ETMD. VT and ETFD was higher for right eye surgeries. The optimum MH was between 50 to 55 inches. Overall, neck strain and eye strain were in the range of 0-3 and 0-1, respectively.Conclusion: The various parameters affecting 3D image quality, neck and eye strain are: chair height, viewing tilt angle, eye centration, monitor distance, laterality of the eye and room illumination.

Introduction: Orthoses have been reported to improve function and symptom reduction in knee Osteoarthritis (OA) of the medial compartment. Biomechanical changes introduced instantly in the gait with the use of orthoses can be evaluated to understand their effectiveness. Aim: To determine and compare the immediate effect of valgus knee brace and Lateral Wedge Insole (LWI) on gait parameters in medial compartment OA knee patients. Materials and Methods: This was a cross-sectional study conducted in the Department of Physical Medicine and Rehabilitation at a tertiary centre from August 2018 to July 2019. A 56 patients of knee OA (Kellgren-Lawrence system grades 2 or 3) were assessed by instrumented gait analysis before and just after orthotic fitment. Gait parameters related to External Knee Adduction Moment (EKAM) (e.g., maximum Ground Reaction Force (mGRF), vertical Ground Reaction Forces (vGRF), Varus Angle (VA) were assessed via motion capture during walking, in all four conditions: barefoot (B), LWI, valgus Knee brace (KB), Combined (C) i.e., (LW+KB). Statistical analysis was done using International Business Machines (IBM) Statistical Package for Social Sciences (SPSS) version 24.0. To find the significant difference in given parameters, repeated measure Analysis of Variance (ANOVA) was applied taking p-value <0.05. Results: A total of 56 patients (13 men, 43 women) mean age of 58.04±5.8 years and a mean Body Mass Index (BMI) of 27.4±3.5 kg/m2 were analysed. A 35 patients had OA grade 2 and 21 were classified as grade 3. No significant difference in mean vGRF and VA values was found among LW, KB and C (p=0.118) and (p=0.894) throughout the stance phase. The significant difference was in mean mGRF values during initial stance phase (0-20% of gait cycle) (p=0.036). Conclusion: The orthoses may not swiftly provide beneficial biomechanical changes in gait parameters of medial OA knee patients.
