Epidemiology of mammal bite injuries: 5 year review of a level II regional referral hospital in Mexico city

Background: Animal bites are a common cause of primary care and emergency department attention worldwide. However, the incidence of this pathology among Mexican population is not well known. Plastic surgeons are at the forefront of initial attention and final outcome of these destructive wounds in our country. The aim of this study was to describe the epidemiology of animal bites over a 5 year period at a level II general hospital in Mexico city. Objective of current study was to determine the incidence of animal bites in hospital “Rubén Leñero” in Mexico city over a 5-year periodMethods: Retrospective study; records of emergency room of all adult patients who sustained animal bites between January 2016 to December 2020 were collected. Details about age, gender, and location of the injuries were recorded and analyzed.Results: From a total of 277 cases, 273 were dog bites (98.56%) and 4 cat bites (1.44%), 173 males (62.45%) and 104 females (37.55%) were affected. The two most injured places in the human body were the hand with 98 cases (35.37%), followed by the lips in 45 cases (16.25%).Conclusions: Animal bites are a frequent injury in the primary care unit, representing a health issue in our country. Proper patient evaluation and treatments are essential to prevent further complications and subsequent infections. Further investigation will be required to establish risk factors for this pathology

Comparison of Nasal Analysis by Photographs (2D) against Low-cost Surface Laser Imaging (3D) and against Computed Axial Tomography Imaging

Introduction In aesthetic surgery, we have a few evaluation tools that numerically and objectively measure the changes we make in patients. This article aimed to evaluate the nasal systematic analysis and compare findings between the three systems of nasal evaluation: photographs 2D, 3D surface imaging with the Kinect system, and 3D CT scan imaging. Methods We designed a longitudinal and descriptive prospective study with simple non-blind randomization. To compare the systematic nasal analysis between the three methods. If the findings are similar, all three methods would be useful in independent clinical scenarios. Results A total of 42 observations were included finding a minimum age of 21 with a mean of 28 years old. Also, 64% were female, 93% had adequate facial proportions, and 50% were Fitzpatrick III. For outcome statistics, we found differential nasal deviation between 3D images with a mean of 6.53 mm. While when comparing the nasal dorsum length, we found a statistical significance of p = 0.051. When comparing the nasal dorsum length index, we found no significant difference p = 0.32. Also, we did not find statistical significance when comparing the nasofrontal angle and tip rotation angle p = 1 for both. Conclusion We found that the population we serve has characteristics of Hispanic mestizo nose. The three methods seem to evaluate systematic nasal analysis in a very similar way, and any of them can be used depending on the scenario and the needs of plastic surgeons
