Surgical treatment of zygomatic bone fracture using two points fixation versus three point fixation-a randomised prospective clinical trial

<p>Abstract</p> <p>Background</p> <p>The zygoma plays an important role in the facial contour for both cosmetic and functional reasons; therefore zygomatic bone injuries should be properly diagnosed and adequately treated. Comparison of various surgical approaches and their complications can only be done objectively using outcome measurements which in turn require protocol management and long-term follow up. The preference for open reduction and internal fixation of zygomatic fractures at three points has continued to grow in response to observations of inadequate results from two point and one point fixation techniques.</p> <p>The objectives of this study were to compare the efficacy of zygomatic bone after treatment with ORIF using 2 point fixation and ORIF using 3 point fixation and compare the outcome of two procedures.</p> <p>Methods</p> <p>100 patients were randomly divided equally into two groups. In group A, 50 patients were treated by ORIF using two point fixation by miniplates and in group B, 50 patients were treated by ORIF using three point fixation by miniplates. They were evaluated for their complications during and after surgery with their advantages and disadvantages and the difference between the two groups was observed.</p> <p>Results</p> <p>A total of 100 fractures were sustained. We found that postoperative complication like decreased malar height and vertical dystopia was more common in those patients who were treated by two point fixation than those who were treated with three point fixation.</p> <p>Conclusions</p> <p>Based on this study open reduction and internal fixation using three point fixation by miniplates is the best available method for the treatment zygomatic bone fractures.</p

Self-care and its predictors among patients with heart failure in Karachi, Pakistan.

Background: Self-care in heart failure (HF) is essential to improve Quality of Life (QoL) and reduce hospital readmissions. It is a well-researched phenomenon in western countries but still unexplored in developing countries like Pakistan. Aim: The aim of this study was to explore the level of self-care behaviour (SCB) and its associated factors among patients with HF in Karachi Pakistan. Methods: In a cross-sectional survey, SCB was measured from 230 patients with HF, using the European Heart Failure Self-Care Behavior scale (EHFSCBs_9). Its associated factors were assessed via a self-developed checklist prepared by the researcher (lead author). Results: The overall mean of SCB was 29.73+/-7.03. As a result of multi-variable regression analysis, out of the six variables, only three variables were significantly associated with SCB, explaining the 23.4% variance. These variables were education; income; and chronicity of HF diagnosis. Conclusion: The findings of the study suggest that public health initiatives in the form of supportive-educative interventions are a dire need to enhance self-care among patients with HF
