Bite Wounds

Objectives The aim of this study was to describe a series of cats suffering from thoracic dog bite wounds, in order to detail the clinical, radiographic and surgical findings, and evaluate outcomes and factors associated with mortality. Methods The medical records of cats with thoracic dog bite wounds presenting to a single institution between 2005 and 2015 were retrospectively reviewed. Data relating to clinical presentation, wound depth and management, radiographic findings, surgical findings and mortality were collected. Wound depth was defined as no external wound, superficial, deep or penetrating, and wound management was defined as conservative, exploratory or thoracic exploration. Statistical analyses were performed using Fisher’s exact test, the Mann–Whitney U-test and the χ2 test. Results Twenty-two cats were included, of which two were euthanased on presentation. In cats where wound depth could be assessed (21/22), six had no external wounds, four had superficial wounds, three had deep wounds and eight suffered penetrating wounds. Sixteen cats also suffered wounds elsewhere, most commonly to the abdomen. Neither an abdominal wound nor abdominal surgery were associated with mortality. Pneumothorax was the most common radiographic finding (11/18). Individual radiographic lesions were not significantly associated with respiratory pattern, presence of pseudo-flail, need for thoracotomy or lung lobectomy, or survival. The presence of ⩾3 radiographic lesions was associated with the presence of a penetrating wound ( P = 0.025) and with having thoracic exploration ( P = 0.025). Local exploration was performed in 7/20 cats, while 8/20 underwent thoracic exploration. Wound management type was not significantly associated with mortality. Overall mortality rate was 27%. Conclusions and relevance Presence of ⩾3 radiographic lesions should raise suspicion of a penetrating injury and may be suggestive of injury requiring a greater level of intervention. The treating veterinarian should have a high index of suspicion for penetrating injury and be prepared in case thoracic exploratory surgery is necessary, particularly in the presence of pseudo-flail chest, pneumothorax or ⩾3 radiographic lesions.

Background: Radiography is the initial imaging modality used to evaluate femoroacetabular impingement (FAI), and diagnostic radiographic findings are well-established. However, the prevalence of these radiographic findings in patients with hip pain is unknown. Purpose: The purpose was 3-fold: (1) to determine the overall prevalence of radiographic FAI deformities in young patients presenting with hip pain, (2) to identify the most common radiographic findings in patients with cam-type FAI, and (3) to identify the most common radiographic findings in patients with pincer-type FAI. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A geographic database was used to identify patients aged 14 to 50 years with hip pain between the years 2000 to 2016. The following were evaluated on radiographs: cam type: typical pistol grip deformity, alpha angle >55°; pincer type: crossover sign (COS), coxa profunda or protrusio acetabuli, lateral center edge angle (LCEA) ≥40°, Tönnis angle <0°; and mixed type: both cam- and pincer-type features. Posterior wall sign (PWS) and ischial spine sign (ISS) were also evaluated. The prevalence of each was determined. Descriptive statistics were performed on all radiographic variables. Results: There were 1893 patients evaluated, and 1145 patients (60.5%; 1371 hips; 374 male and 771 female; mean age, 28.8 ± 8.4 years) had radiographic findings consistent with FAI. Of these hips, 139 (10.1%) had cam type, 245 (17.9%) had pincer type, and 987 (72.0%) had mixed type. The prevalence of a pistol grip deformity and an alpha angle >55° was 577 (42.1%) and 1069 (78.0%), respectively. The mean alpha angle was 66.9°± 10.5°. The prevalence of pincer-type radiographic findings was the following: COS, 1062 (77.5%); coxa profunda, 844 (61.6%); ISS, 765 (55.8%); PWS, 764 (55.7%); Tönnis angle <0°, 312 (22.8%); LCEA ≥40°, 170 (12.4%); and protrusio acetabuli, 7 (0.5%). Conclusion: The overall prevalence of radiographic findings consistent with FAI in young patients with hip pain was 60.5%. Radiographic findings for mixed-type FAI were the most prevalent. The most common radiographic finding for cam-type FAI was an alpha angle >55°. The most common radiographic finding for pincer-type FAI was the COS.

Summary Background: Primary bite wound suturing in the emergency department remains controversial in some cases. Objective: We conducted a study to investigate the infection rate and cosmetic appearance between primary wound closure and delayed wound closure in dog bite wounds in humans. Methods: All patients with bite wounds were treated with oral antibiotic medications. We adopted a randomized cohort study, dividing the patients who needed wound closure into two groups: 60 patients for primary closure, and 60 patients for delayed closure, and compared the infection rate and wound cosmetic appearance scores. Results: In the primary closure group, four people (6.7%) developed a wound infection without systemic infection. In the delayed closure group, three people (5%) developed a wound infection (p = 0.093), but there were not any patients that developed a systemic infection. Thirty-three patients (55%) in the primary closure group had optimal cosmetic scores, whereas 20 patients (33.3%) in the delayed closure group had optimal cosmetic scores (p = 0.012). Conclusion: Although primary wound closure for dog bites may be associated with a higher infection rate, the cosmetic appearance after primary closure was still acceptable.

Rabies Prevention

Background: Rabies is a fatal zoonotic disease of the central nervous system, most commonly caused by the bite of rabid dogs. Globally canine rabies causes 59,000 human deaths, over 3.7 million DALYs and 8.6 billion USD economic losses annually. These losses are due to a lack of knowledge about wound management and post-exposure prophylaxis. The objective of the study was to assess the knowledge and practices following dog bite and its management among the urban and rural population.Methods: A cross-sectional study was conducted in the field practice area of KIMS, Hubli. 120 households of the urban and rural locality were interviewed with a semi-structured pretested questionnaire.Results: Overall 89.16% of the study population was aware that the disease can be prevented by vaccination. 35% of the rural and 28% of the urban population believed that the disease can spread from person to person. The knowledge about the site and the number of doses of vaccine was poor among both the population. The harmful practices for treatment of bite were still prevalent among both rural (25%) and urban (8.3%) population.Conclusions: The knowledge about the dog bite management and Rabies prevention is insufficient among both populations. There are myths and misconceptions about the disease and wound management. Practices like application of harmful substances like lime, turmeric, mud are the problems hindering rabies prevention and control. Proper steps need to be taken up to control the canine rabies.

Objective To describe chest radiographic findings in patients with isolated and complicated acute novel influenza A (H1N1) virus infection. Methods Retrospective study of 147 patients (64 men, mean age 41) with reverse-transcriptase polymerase chain reaction confirmed acute influenza A (H1N1) infection, who also had a chest radiograph <72 hours of viral specimen collection. Radiographs were analysed for acute findings. A correlation with bacterial cultures results was performed. The unpaired 2-sample equal-variance Student t test was applied to continuous variables and the Pearson χ2 test of association to discrete variables. Results In 71% of cases, chest radiograph was normal. The presence of acute imaging findings was associated with older age ( P < .05), increased number of comorbidities (most commonly, chronic obstructive pulmonary disease, diabetes, asthma) ( P < .05), higher rate of hospitalization ( P < .05) and intensive care unit admission, and increased mortality. Predominant acute radiographic finding in isolated influenza A (H1N1) was alveolar opacity (88%), either unifocal or multifocal, most often in the lower lobes. In the subgroup of patients with positive imaging findings and for whom nonviral microbiologic data was available, 62% had superimposed bacterial or fungal infection. Conclusion In the majority of patients with acute influenza A (H1N1) infection, the chest radiograph is normal. Acute imaging findings are associated with older age, an increased number of comorbidities, and a higher rate of complications and mortality. The predominant radiographic finding of isolated primary influenza A (H1N1) infection is alveolar opacity. Superimposed bacterial infection is frequent and must be excluded in patients with abnormal imaging.
