The diploma in family medicine examination; a scientific exercise

The Diploma in Family Medicine (DFM) Examination Is a new certification offered by the College of Physicians and Surgeons of Pakistan, and its Department of Medical Education designed a scientific examination. First, the Expert Advisory Committee for Family Medicine was formed, relevant training objectives Were determined, a training programme to achieve the objectives was designed and a valid syllabus was chosen. Then the examination was designed, where the candidates must pass the objective theory papers before taking the clinical examination. The clinical examination consisted of an Objective Structured Clinical Examination (OSCE) and traditional case presentations. The candidates had to pass each of the components, and attain an overall aggregate of 60%. In the first six examinations, 752 candidates sat for the theory examinations, 332(44.14%) were eligible for the clinical examination, and 170 (23%) passed. If 60% marks obtained in case presentations is taken as the gold standard which is the current CPSP policy and compared to OSCE marks, then 75% marks in OSCE had a sensitivity of 67% and a specificity of 79

The linked nail/plate construct for the management of distal femur fractures in the elderly

Background: Distal femoral fractures represent a challenging injury, with many different factors such as the method of fixation, complexity of fracture pattern, and patient co-morbidities affecting the outcome. Lots of surgical treatment options have been described, but recently double construct fixation, using a nail/plate combination, has received lots of attention, a technique that leads to faster weight-bearing, low risk of metalwork failure, and non-union. The purpose of this study was to investigate the effectiveness of the linked nail/plate construct in the management of complex distal femur fractures and to investigate if the above technique leads to faster recovery and earlier radiographic union. Materials and methods: In total 15 cases were included in the study, that underwent a combined nail/plate construct for a distal femur fracture between January 2021 and December 2022. Only cases with a linked nail/plate construct were included, with a minimum follow-up of 1 year. Open femur fractures, single implant fixation cases, and revision procedures were excluded. Results: In this cohort study, 11 cases were periprosthetic distal femur features, and 4 cases were distal femur fractures around a native knee joint. The mean age group was 74 years, 86.6% of the patients had a BMI > 25 and the mean time to fracture union was 24 weeks (range from 20 to 26 weeks). All cases healed uneventfully and the complication rate was 6.6%, including 1 case of superficial infection which resolved completely with oral antibiotics. Conclusion: The increasing age population, the complexity of distal femoral fractures along with the increasing physiological demands of the elderly population, drive the need for double fixation constructs that allow early mobilization and enhance fracture stability. In our study, the linked nail/plate construct seems to provide adequate stability and excellent union rates (100%) with no associated increased risk of complications

5-(5-Bromo-2-methoxyphenyl)-2-fluoropyridine

In the title compound, C12H9BrFNO, the dihedral angle between the aromatic rings is 51.39 (5)°; the C atom of the methoxy group is close to being coplanar with its attached ring (r.m.s. deviation = 0.0172 Å] and is oriented away from the pyridine ring. In the crystal, molecules interact by van der Waals forces

4-(2-Fluoropyridin-5-yl)phenol

In the title compound, C11H8FNO, the aromatic rings are oriented at a dihedral angle of 31.93 (6)°. In the crystal, molecules are linked by O—H...N hydrogen bonds, forming C(9) chains propagating along the c-axis direction. There are aromatic π–π stacking interactions between the pyridine rings [centroid–centroid separation = 3.7238 (16) Å]

A Spatiotemporal Saliency Model for Video Surveillance

International audienceA video sequence is more than a sequence of still images. It contains a strong spatial-temporal correlation between the regions of consecutive frames. The most important characteristic of videos is the perceived motion foreground objects across the frames. The motion of foreground objects dramatically changes the importance of the objects in a scene and leads to a different saliency map of the frame representing the scene. This makes the saliency analysis of videos much more complicated than that of still images. In this paper, we investigate saliency in video sequences and propose a novel spatiotemporal saliency model devoted for video surveillance applications. Compared to classical saliency models based on still images, such as Itti's model, and space-time saliency models, the proposed model is more correlated to visual saliency perception of surveillance videos. Both bottom-up and top-down attention mechanisms are involved in this model. Stationary saliency and motion saliency are, respectively, analyzed. First, a new method for background subtraction and foreground extraction is developed based on content analysis of the scene in the domain of video surveillance. Then, a stationary saliency model is setup based on multiple features computed from the foreground. Every feature is analyzed with a multi-scale Gaussian pyramid, and all the features conspicuity maps are combined using different weights. The stationary model integrates faces as a supplement feature to other low level features such as color, intensity and orientation. Second, a motion saliency map is calculated using the statistics of the motion vectors field. Third, both motion saliency map and stationary saliency map are merged based on center-surround framework defined by an approximated Gaussian function. The video saliency maps computed from our model have been compared to the gaze maps obtained from subjective experiments with SMI eye tracker for surveillance video sequences. The results show strong correlation between the output of the proposed spatiotemporal saliency model and the experimental gaze maps
