Management of Human Bites in a Rural Kenyan Setting: A Plastic Surgeon's 8-Year Experience.

INTRODUCTION: The treatment of human bites is a common issue facing healthcare practitioners in the developing countries of Sub-Saharan Africa where it has been noted as a growing public health concern. Generally, the desired outcomes from surgical management are healing, function, and aesthetics. We share our 8-year experience at Kapsowar Hospital in Kenya with the presentation, management, and outcome of human bites. We are uniquely situated to do so given the prevalence of human biting in our community and the full-time presence of a plastic surgeon at our institution. To the best of our knowledge, this study is the first to present human bite surgical management by a plastic surgeon certified by the American Board of Surgery working full-time on the African continent. METHODS: A retrospective chart review was conducted on all patients who presented to the operating theater at Kapsowar Hospital with a human bite between 2013-2021. After identification of eligible patients, charts were reviewed assessing parameters including age, gender, timing from injury to presentation at hospital, localization of bite, severity of facial wounds using Lackmann's classification, surgical procedure(s), postoperative complications, surgical revisions, antibiotics administered, and circumstance of incident. Data were analyzed using SPSS 29.0.0.0. RESULTS: Forty-four patients were identified. Seventeen (38.6%) were female and 27 (61.4%) were male. Thirty-one patients had facial bites and 13 patients had bites to other parts of the body. Of facial bites, 70.3% resulted in amputation of the affected part while 29.7% were lacerations. Using Lackmann's classification for facial bite severity, IIIA bites (complete avulsion) were most common for both males (9) and females (7). Females comprised 68.4% of total lip bite victims. Bites to the extremity were associated with late presentation and infection. We report a salvage rate of 85.7% for infected digits. CONCLUSIONS: Compared with most other studies on human bites, our patient population presents with a higher rate of avulsive lip injuries, most commonly among women. Our postoperative infection rate is lower than many others reported in the literature. Satisfactory cosmetic outcome with low risk of infection can be achieved by following well-established principles of wound healing and tension-free closure.

An Observational Study of Patient Characteristics and Environmental Risk Factors of Stingray Envenomations in San Diego, California.

INTRODUCTION: Current literature on stingray envenomations focuses on the incidence, presentation, and complications of these injuries, with some studies providing such data for specific geographic locations. This is the first study to evaluate the influence of environmental factors and human characteristics on stingray envenomation patterns in San Diego, California. METHODS: Incident reports of injuries documented by the San Diego Fire-Rescue Department/Lifeguard Division (SDFR-LG) during 2017 were analyzed. Water temperature and tide height were populated based on date and time. Data was analyzed for associations between stingray injuries incidence and tide height, water temperature, time, month, age and sex of the injured person, and whether they were local. RESULTS: 1722 stingray injuries were reported to the SDFR-LG in 2017. Stingray injuries were associated with water temperature (p < 0.001), more frequently occurring between 18.8 °C and 19.5 °C. Most envenomations occurred at tide heights between 1.7 ft and 3.1 ft. Most victims were aged 20-29, and there were more males than females injured. Beaches separated from the greater ocean or with a reef bottom had a lower incidence. Stingray injuries were more frequent during summer months. More stingray envenomations were documented for out-of-town beachgoers. CONCLUSIONS: Beachgoers with certain characteristics had more reported stingray envenomations than others. Males, nonlocal beachgoers, and individuals in their twenties had more injuries than their counterparts. Stingray injuries were more common at water temperatures between 18.8 and 19.5 °C. These findings may lead to future research on the prevention of stingray injuries.

Exposure History, Post-Exposure Prophylaxis Use, and Clinical Characteristics of Human Rabies Cases: A Twelve-Year Retrospective Review at a Tertiary Facility in Ghana.

BACKGROUND: Robust monitoring and reporting systems for rabies are lacking thus increasing the risk of underreporting. Highlighting the rabies cases brings to bear the needed urgent attention for more efforts at preventing and controlling the disease. OBJECTIVE: To describe the epidemiological characteristics of patients managed for clinical rabies at the largest referral facility in Ghana. METHODS: A retrospective single-center hospital-based chart review and data extraction were conducted for persons managed for clinical rabies infection at the Korle-Bu Teaching Hospital from January 2008 to December 2019. Data analysis was done using STATA. Descriptive statistics were used to summarize the epidemiological and clinical characteristics. Fisher's exact test, the Kruskal-Wallis test, and Spearman's correlation coefficient were used to explore significant associations. RESULTS: A total of 28 cases were recorded over the period of review. All of them died and most (68%) of them were males. Twenty-one percent of them were less than 15 years old. Their median age interquartile range (IQR) was 31 years (25.5 years) and the median incubation period for rabies (IQR) was 60 days (60 days). The source of rabies for cases was mainly dog bites. The vaccination status of all the animals could not be ascertained. Majority (80%) of the patients took neither anti-rabies vaccine nor immunoglobulin as post-exposure prophylaxis after the dog bite. The median time of admission before death (interquartile range) was 2 days (2 days). Majority (82%) of the cases were furious rabies. CONCLUSION: Attention should be directed at mass vaccination of dogs as dog bites are common. Ensuring availability and access to post-exposure prophylaxis (PEP) is also critical in averting rabies-related deaths.

CONTEXTE: Des systèmes de surveillance et de déclaration robustes pour la rage font défaut, augmentant ainsi le risque de sousdéclaration. Mettre en lumière les cas de rage suscite l'attention urgente nécessaire pour redoubler d'efforts dans la prévention et le contrôle de la maladie. OBJECTIF: Décrire les caractéristiques épidémiologiques des patients traités pour une rage clinique dans le plus grand établissement de référence au Ghana. MÉTHODES: Une revue rétrospective des dossiers médicaux et une extraction de données basées à l'hôpital ont été réalisées pour les personnes traitées pour une infection à la rage clinique à l'Hôpital d'Enseignement Korle-Bu de janvier 2008 à décembre 2019. L'analyse des données a été effectuée à l'aide de STATA. Des statistiques descriptives ont été utilisées pour résumer les caractéristiques épidémiologiques et cliniques. Le test exact de Fisher, le test de Kruskal-Wallis et le coefficient de corrélation de Spearman ont été utilisés pour explorer les associations significatives. RÉSULTATS: Un total de 28 cas ont été enregistrés sur la période examinée. Tous sont décédés et la plupart d'entre eux (68%) étaient des hommes. Vingt et un pour cent d'entre eux avaient moins de 15 ans. Leur âge médian (plage interquartile) était de 31 ans (25,5 ans) et la période d'incubation médiane de la rage (plage interquartile) était de 60 jours (60 jours). La principale source de rage pour les cas était principalement les morsures de chiens. Le statut vaccinal de tous les animaux n'a pas pu être déterminé. La majorité (80%) des patients n'ont pris ni vaccin antirabique ni immunoglobuline en prophylaxie post-exposition après la morsure de chien. Le délai médian d'admission avant le décès (plage interquartile) était de 2 jours (2 jours). La majorité (82%) des cas étaient atteints de rage furieuse. CONCLUSION: L'attention devrait être dirigée vers la vaccination de masse des chiens car les morsures de chien sont courantes. Assurer la disponibilité et l'accès à la prophylaxie post-exposition (PPE) est également crucial pour éviter les décès liés à la rage. MOTS-CLÉS: Rage, morsure de chien, post-exposition, prophylaxie, vaccination de masse.

Legal epidemiology of paediatric dog bite injuries.

BACKGROUND: Dog bite injuries cause over 100 000 paediatric emergency department visits annually. Our objective was to analyse associations between regional dog ownership laws and incidence of paediatric dog bites. METHODS: This observational study used an online search to locate local dog-related policies within Ohio cities. Data collected by Ohio Partners For Kids from 2011 through 2020 regarding claims for paediatric dog bite injuries were used to compare areas with and without located policies and the incidence of injury. RESULTS: Our cohort consisted of 6175 paediatric patients with dog bite injury encounters. A majority were white (79.1%), male (55.0%), 0-5 years old (39.2%) and did not require hospital admission (98.1%). Seventy-nine of 303 cities (26.1%) had city-specific policies related to dogs. Overall, the presence of dog-related policies was associated with lower incidence of dog bite injury claims (p=0.01). Specifically, metropolitan areas and the Central Ohio region had a significantly lower incidence when dog-related policies were present (324.85 per 100 000 children per year when present vs 398.56 when absent; p<0.05; 304.87 per 100 000 children per year when present vs 411.43 when absent; p<0.05). CONCLUSIONS: The presence of city-specific dog-related policies is associated with lower incidence of paediatric dog bite injury claims, suggesting that local policy impacts this important public health issue. There are limited dog-related policies addressing dog bite prevention, with inconsistencies in breadth and depth. Creating consistent, practical requirements among policies with vigorous enforcement could ameliorate public health concerns from paediatric dog bite injuries.

Study of dog control strategies.

OBJECTIVES: (1) To explore the relationship between regionally implemented dog control strategies and dog bite injuries (DBIs) and (2) to evaluate current implementation of dog control strategies. METHODS: Observational study using a nationwide online survey of territorial authorities (TAs). Domains of interest included complaints for attacks on people, dog population, primary and secondary prevention strategies, resourcing and perspectives of current strategies. Quantitative variables were compared with DBI Accident Compensation Corporation (ACC) claims by region from 2014 to 2018. RESULTS: Two-thirds of TAs (70%; n=47/67) responded to the survey. No clear relationship was observed between DBIs and: registered dog population, proportion sterilisations or microchipping, classifications due to dog behaviour, or existing limited resourcing. Legislated breeds and infringements for failure to control a dog or non-registration were higher in areas with greater DBIs. Educational messages varied widely and were predominantly victim directed (67%; n=71/106). Complaints for dog attacks on people were lower than DBIs in most areas, with no formal cross-agency notification policies. Few prosecutions or dog destruction orders were made. CONCLUSIONS: Regional inequity in DBIs could not be explained by differences in the registered dog population or dog control strategies. Minimal and inequitable resourcing exists to implement current dog control strategies and provide owner-directed education. Gaps in legislation include environmental barrier requirements for all dogs (leash/muzzle use, adequate fencing), notification of incidents and child protection. Partnership with the Indigenous community (Maori) and other community groups will be required to implement these measures successfully.

Pediatric Dog Bites to the Face May Have Been Less Severe During COVID-19 Pandemic: A Retrospective Cohort Study.

PURPOSE: Pediatric dog bite injuries are one of the most common nonfatal injuries. During the COVID-19 pandemic, children stayed at home more than pre-pandemic. The effect of the pandemic on severity of dog bites to the face in children has not been examined. The objective of this study was to determine the frequency and severity of dog bite injuries to the face in children during the first year of the COVID-19 pandemic when compared to the previous year. MATERIALS AND METHODS: A retrospective cohort study was conducted for children with dog bite injuries to the head and neck region who presented to the emergency department at Children's Healthcare of Atlanta from March 2019 to March 2021. The predictor variable was the time of injury, and this was divided into pre-lockdown [control group (March 15, 2019, to March 15, 2020), ie pre-L] and lockdown (March 15, 2019, to March 15, 2020), ie post-L. The outcome variable was severity of dog bite defined as one or more of the following: 1) patient required sedation or general anesthesia for repair, 2) 3 or more regions in the head and neck were involved, and/or 3) surgical consultation took place. The investigators used a two-sample t-test, multivariable linear regression models, and modified analysis of variance and multivariate ANOVA tests to analyze the data (P-value < .05 determined significance). RESULTS: 712 children (370 males) with an average age of 6 years old (range, 7 months-18 years) fit the inclusion criteria. There were 381 cases in the pre-L and 331 in the post-L period. There were more cases on average per month pre-L (31.8 cases/month) than post-L (27.6 cases/month) (P-value = .26). There were 183 pre-L surgical consults compared to 75 post-L (48 vs 22.8% of cases, respectively; P-value ≤ .001). There were 52 pre-L cases that had 3 or more sites in the head and neck compared to 28 during the post-L period (P-value = .032). CONCLUSIONS: During the COVID-19 pandemic, there may have been a decrease in the severity of dog bite injuries. This trend may demonstrate a consequence that is not a direct result of the virus.

The Association of Antimicrobial Prophylaxis With Return Visits After Dog Bites in Children.

OBJECTIVES: Dog bites occur frequently in the United States, yet there are no clear guidelines for prescribing antibiotic prophylaxis in healthy children after a dog bite. The aim of our study was to assess antibiotic prophylaxis and subsequent rates of infection after dog bites in children. We hypothesized a negative association between prophylactic prescription of any antimicrobial and return visit within 14 days for infection. METHODS: In this retrospective cohort study, we assessed the frequency of antibiotic prophylaxis prescribed after dog bite injuries in patients 0 to 18 years old and subsequent return visits for infection using 2016 to 2017 medical and pharmacy claims derived from the IBM MarketScan Research Databases. We used the International Classification of Diseases-10 code W54 for dog bites then used keyword searches to find diagnoses (including infection), wound descriptions, and medications. RESULTS: Over the 2-year period, 22,911 patients were seen for dog bites that were not coded as infected. The majority, 13,043 (56.9%), were prescribed an antibiotic at the initial visit and 9868 (43.1%) were not. Of those prescribed antibiotics, 98 (0.75%; 95% confidence interval [CI], 0.60-0.90) returned with an infection, compared with 59 (0.60%; 95% CI, 0.44-0.75) of those not prescribed antibiotics. Receiving an antibiotic prescription at the initial visit was associated with a reduced rate of return for wound infection only among children whose wounds were repaired or closed. Children not receiving a prescription whose wounds were repaired were more than twice as likely to return with an infection in the subsequent 14 days as children whose wounds were not repaired (odds ratio, 2.2; 95% CI, 1.2-4.0). CONCLUSIONS: Most children are prescribed antibiotics at an initial emergency department visit after a dog bite. However, very few return for infection independent of antimicrobial prophylaxis, which suggests antibiotics are overprescribed in this setting.

Dog bite management practices by general practitioners; where are we standing in ASIA; a narrative review.

Rabies is an infectious viral disease endemic worldwide and is fatal after the onset of clinical symptoms. In 99% of cases, dogs contribute to infectious viral transmission in humans. It causes approximately 10,000 deaths per year, mainly in Asia and Africa, with 95% of deaths occurring in Asia alone. Currently, the number of dog bite cases reported in Pakistan is alarming. Such cases are first seen mostly by general practitioners. The current narrative review was planned to assess the knowledge, attitude and practices of general practitioners as reported in the literature from different countries published between July 2016 and February 2021 regarding dog bite management. Articles were searched using Google, Google Scholar, Ovid, Eric and PubMed databases. Keywords used included rabies, dog bite, general practitioners, medical officers, knowledge, attitude and practices. A total of 7 studies comprising 875 participants were included. Because of the increasing human population, a growing number of dogs and a lack of concerted efforts for the control of disease, the burden of human deaths as a result of rabies will continue to escalate.

Pandemic Puppies: Man's Best Friend or Public Health Problem? A Multidatabase Study.

INTRODUCTION: The public health implications of the COVID-19 pandemic reach beyond those of the disease itself. Various centers have anecdotally reported increases in the incidence of dog bite injuries which predominate in pediatric populations. The reasons for this increase are likely multifactorial and include an increase in canine adoptions, remote learning, and psychosocial stressors induced by lockdowns. We hypothesized that there was a significant increase in the proportion of dog bite injuries at our institution and within a nationally representative cohort. METHODS: We queried our electronic health record and the National Electronic Injury Surveillance System (NEISS) for all records pertaining to dog bites between 2015 and 2020, and the annual incidence was calculated. Poisson regression was then used to estimate whether there was a significant difference in the adjusted risk ratio for each year. RESULTS: The institutional and national cohorts revealed relative increases in the incidence of dog bite injury of 243 and 147.9 per 100,000 over the study period, respectively. Both cohorts observed significant increases of 44% and 25% in the annual incidence relative to 2019, respectively. Poisson regression revealed a significantly elevated adjusted relative risk in the institutional cohort for 2020 (2.664, CI: 2.076-3.419, P < 0.001). The national cohort also revealed an increase (1.129, CI: 1.091-1.169, P < 0.001). CONCLUSIONS: A nationwide increase in the incidence of dog bite injuries among children was observed during COVID-19 in 2020. These findings suggest that dog bites remain a public health problem that must be addressed by public health agencies.

Capnocytophaga zoonotic infections: a 10-year retrospective study (the French CANCAN study).

Zoonotic species of Capnocytophaga genus belong to the oral microbiota of dogs and cats. They may be responsible for serious human infections, mainly after animal bites, with a high mortality rate. In France, only few cases have been reported and no multicenter study has been conducted. Our aim was to describe the French epidemiology of Capnocytophaga zoonosis. We conducted a multicenter (21 centers) retrospective non-interventional, observational study in France describing the epidemiology of Capnocytophaga zoonosis (C. canimorsus, C. cynodegmi, C. canis) over 10 years with regard to clinical and bacteriological data. From 2009 to 2018, 44 cases of Capnocytophaga zoonotic infections were described (C. canimorsus, n = 41; C. cynodegmi, n = 3). We observed an increase (2.5 times) in the number of cases over the study period (from the first to the last 5 years of the study). The most frequent clinical presentations were sepsis (n = 37), skin and soft tissue infections (n = 12), meningitis (n = 8), osteoarticular infections (n = 6), and endocarditis (n = 2). About one-third of patients with sepsis went into septic shock. Mortality rate was 11%. Mortality and meningitis rates were significantly higher for alcoholic patients (p = 0.044 and p = 0.006, respectively). Other comorbidities included smoking, splenectomy, diabetes mellitus, and immunosuppressive therapy are associated to zoonotic Capnocytophaga infection. Eighty-two percent of cases involved contact with dogs, mostly included bites (63%). Despite all isolates were susceptible to the amoxicillin-clavulanic acid combination, three of them were resistant to amoxicillin.

Child safety programs for primary school children decrease the injury severity of dog bites.

This study focuses on the impact of a prevention program regarding dog bites in children. As a consequence of our previous investigation in 2005, we have initiated a child safety program for primary school children starting January 2008 until present to teach children how to avoid dog attacks and how to behave in case of an attack. In our retrospective study, we analyzed all patients younger than 15 years presenting with dog-related injuries between 2014 and 2018. As the main indicator for success of the prevention measures taken, we have defined the severity of injury in comparison to our previous study. Out of 296 children with dog-related injuries, 212 (71.6%) had sustained a dog bite. In the vast majority (n = 195; 92%), these patients presented with minor injuries; the extremities were most commonly affected (n = 100; 47%). Injuries to the head (n = 95; 45%) and trunk (n = 18; 8%) were less frequent. The proportion of severe injuries (8%) was significantly lower compared to our previous study, where 26% of children presented with severe injuries necessitating surgical intervention, while the number of patients requiring in-hospital treatment declined from 27.5% in the period 1994-2003 to 9.0% in the period between 2014 and 2018 (p < 0.05).Conclusion: Teaching of primary school children may effectively reduce the injury severity of dog bites. What is Known: • Dog bites are a substantial healthcare problem especially in children. What is New: • This study shows that a broad-based prevention program for primary school children can effectively decrease the severity but not the frequency of dog bite injuries in children.

Systematic review of dog bite prevention strategies.

BACKGROUND: The prevention of dog bites is an increasingly important public health topic, as the incidence of serious injury continues to rise. OBJECTIVES: To evaluate the effectiveness of interventions to prevent dog bites and aggression. METHODS: Online databases were searched (PubMed, Cochrane Library, Embase and Google Scholar), using the search terms: dog/s, canine, canis, kuri, bite/s, bitten, aggression, attack, death, fatal, mortality, injury/ies, prevention, intervention, for studies between 1960 and 2021. All study designs were considered. Outcomes of interest were the incidence of dog bites or dog aggression. Non-English studies, and those without full-text access were excluded. RESULTS: Forty-three studies met the review criteria, including 15 observational and 27 interventional studies. Fifteen studies investigating dog-control legislation, including leash laws, stray dog control and infringements indicated this can reduce dog bite rates. Breed-specific legislation had less of an effect. Six studies investigating sterilisation, showed while this may reduce dog bites through a reduction in the dog population, the effect on dog aggression was unclear. An alcohol reduction programme showed a significant reduction in dog bite rates in one study. Seven studies assessing educational approaches found that intensive adult-directed education may be effective, with one study showing child-directed education was not effective. Eight studies on dog training (two police-dog related), and six evaluating dog medication or diet were generally low quality and inconclusive. CONCLUSIONS: Multiple strategies including effective engagement with indigenous communities and organisations will be required to reduce dog-bites and other incidents involving dog aggression. This review provides some evidence that legislated dog control strategies reduce dog bite rates. Available evidence suggests greater restrictions should be made for all dogs, rather than based on breed alone. Due to a burden of child injury, protection of children should be a focus of legislation and further investigations. Prevention strategies in children require redirection away from a focus on child-directed education and future research should investigate the effectiveness of engineering barriers and reporting strategies.

Early Childhood (0 to 5 years) Presents the Greatest Risk for Facial Dog Bites.

PURPOSE: The purpose of the present study is to compare the characteristics of dog bite wounds to the face and that of the rest of the body among the pediatric population in the United States and to determine independent risk factors for dog bite wounds to the face. METHODS: A retrospective cohort study was conducted using the Kids' Inpatient Database. There were multiple, heterogenous predictor variables. The primary outcome variable was a facial dog bite. A multivariate logistic regression was employed to identify independent risk factors for the primary outcome variable. A P value less than .05 was the threshold for statistical significance. RESULTS: Our final sample consisted of 9,057 patients who suffered dog bite injuries, of which 2,913 (32.2%) occurred on the face. Relative to individuals aged 16-20 years, individuals aged 0-5 (odds ratio [OR] 5.7; confidence interval [CI] 4.0, 8.1), 6-10 (OR 3.8; CI 2.6, 5.5), and 11-15 years (OR 1.6; CI 1.1, 2.5) were all independently associated with increased odds of incurring a facial dog bite injury. Patients who were not admitted electively were 2.5 times (CI 1.4, 4.6) more likely to incur a facial dog bite injury relative to patients who were admitted electively. CONCLUSIONS: Young children (0-5 years) were at the greatest risk for facial dog bites relative to children aged 16-20 years. Dog bites that were admitted on emergency were more likely to occur on the face relative to those that were electively admitted to the hospital. To reduce the risk for facial dog bites and the host of chronic psychological ramifications that accompany them, established preventative strategies ought to be exercised.

Pediatric Dog Bites: A Review of 1422 Cases Treated at a Level One Regional Pediatric Trauma Center.

BACKGROUND: Children under the age of 14 account for over 40% of the almost 900,000 annual hospital visits associated with dog bites. Care for dog bites ranges from simple wound irrigation to complex surgical reconstruction. Due to a number of factors, children frequently sustain dog bites to highly vulnerable regions, often necessitating intervention by plastic surgeons. METHODS: This retrospective study analyzed data from the 1422 pediatric patients who sustained dog bites and presented to the Le Bonheur Children's Hospital Emergency Room from January 2011 to May 2017. RESULTS: The typical pediatric dog bite case was male (63.5%), African-American (57.4%), and less than 10 years old (69.4%). The head and neck were the most commonly affected areas (64.7%). Of the head and neck regions, the cheeks and lips were the most frequently injured structures (34.5%). Hospital admission was required for 188 patients (13.2%) and operative repair was deemed necessary in 16.9% of all cases. Of the patients requiring inpatient operative repair, most (78.3%) were discharged in less than 24 hours. Operative complications occurred in 5.8% of all cases, with infections accounting for the majority (92.9%). No fatal dog bites occurred in this study. CONCLUSIONS: Age, bite location, and number of bites sustained are several factors of significance, which may aid the novice plastic surgeon in identifying, which pediatric dog bite cases will require surgical intervention.

Pediatric Dog Bite Injuries: A 5-Year Nationwide Study and Implications of the COVID-19 Pandemic.

INTRODUCTION: Although single institution studies have analyzed various animal attacks, there has not been multicenter investigation into dog bites in children. The purpose of this study was to characterize national trends and investigate the characteristics of pediatric dog bites. METHODS: Aretrospective cohort study was conducted of pediatric dog bite injuries in the United States from 2015 to 2020 using the Pediatric Health Information System national database. Patient characteristics, injury locations, and need for intervention were analyzed. Mann-Whitney U test, Pearson chi-square, and Fisher exact test, and linear multivariate regressions were performed for statistical analysis of data values; statistical significance was maintained at P < 0.05. RESULTS: A total of 56,106 patients were included, majority male (55.1%) with a median age 6.8 years (interquartile range 3.5-10.6). Incidence peaked in July (median =1217) with nadirs in February (median = 760). A substantial increase in bites was seen per overall Emergency Department presentations during the pandemic. Most common bite location was the head (62.1%), followed by the upper extremity (25.1%). Relative proportions of dog bites to the face gradually decreased with age (B = -3.4%/year, P< 0.001), whereas proportions to the upper extremities (B = + 1.9%/year, P < 0.001) and lower extremities (B = + 1.6%/year, P = 0.002) gradually increased with age. Overall, 8.0% patients required repair in the operating suite. injuries isolated to the head (OR= 2.6, P < 0.001) and those to multiple anatomic regions were more likely to require operative intervention [operating room (OR= 2.6, P < 0.001)]. CONCLUSIONS: Dog bites most commonly occur during the summer in school-aged boys. Toddlers disproportionately suffer injuries to the head, with a trend towards upper extremity bites in teenagers. The coronavirus disease 2019 pandemic ushered a spike in dog bite presentations among Emergency Department visits, further underscoring the need for targeted educational initiatives to halt the persistence of these preventable injuries.

Tiger Shark Attack on a Scuba Diver in New Caledonia.

Herein we report an unprovoked shark attack on a scuba diver in New Caledonia. The species responsible for the attack was identified as a tiger shark (Galeocerdo cuvier), based on both the victim's testimony and forensic examination. The victim suffered significant loss of soft tissues from one thigh, which resulted in hemorrhagic shock. Even though the event occurred at a remote location, miles away from the nearest hospital, appropriate first aid, immediate deployment of an alert system, and prompt helicopter transfer by an emergency rescue team allowed the victim to be transferred to an intensive care unit in stable condition and to undergo surgery within 4 h of being bitten. Early coverage of exposed bone was performed, followed up with negative pressure dressing, antibiotic treatment, hyperbaric oxygen therapy, and a split skin graft. In spite of the massive muscular loss incurred, the victim was able to regain her ability to walk within 6 wk of the incident. Shark attacks on scuba divers are rare and seldom reported, especially in New Caledonia.

[A study about the epidemiological characteristics of rabies of the cases of medical treatment from a certain hospital in Beijing from 2011 to 2020].

From 2011 to 2020, there were 111 213 cases of rabies exposed people recruited from the rabies immunization clinic of a hospital in Beijing. The monthly distribution of patients in each year was not statistically significant (P>0.05). The distribution of patients showed remarkable seasonality, with the exposure peak from May to October. The ratio of male to female was 1∶1.3. The majority of patients were aged 20-29 years old (39.1%) and in-service personnel (56.5%). Level-Ⅱ wounds (84.2%) were more common than level-Ⅲ wounds (14.9%). The number of visits to level-Ⅲwounds increased rapidly since 2017. The most common injured body part was hand (60.7%). Dogs were the most common animal for injuries (60.6%), followed by cats (32.3%), of which most were host animals (75.5%). The vaccination rate from 2016 to 2020 [49.8% (24 276/48 703)] was significantly higher than that from 2011 to 2015[18.6% (6 559/35 272)](χ²=8597.18, P<0.001).

Animal bites and post-exposure prophylaxis in Central-West Tunisia: a 15-year surveillance data.

BACKGROUND: Rabies is a disease that still exists in developing countries and leads to more fatalities than other zoonotic diseases. Our study aimed to describe the profile of human exposures to animals over fifteen years and to assess the post-exposure prophylaxis (PEP) practices in the governorate of Kasserine (Tunisia) on pre- and post-revolution (2011). METHODS: We carried out a descriptive study using surveillance data from a region in Central-West Tunisia. All humans exposed to animals, residents in Kasserine Governorate and declared to the regional directorate of primary health care (RDPH) from January 1st, 2004 to December 31st, 2018 were included. RESULTS: A total of 45,564 cases of human exposures to animals were reported over the fifteen-year period of the study with an annual average of 3089.2 ± 403.1. The standardized incidence rate (SIR) of human exposures to animals was 694 per year per 100,000 inhabitants (inh). The most listed offending animal was the dog (91.3%) and the most reported type of exposure was bites (63.7%). The trend in human exposures to animals increased significantly over time. The number of exposures by vaccinated dogs decreased significantly and by unvaccinated and stray dogs increased steeply. When comparing pre-and post-revolution periods, the yearly average of animal exposures post-2011 was significantly greater than the average prior to 2011 (3200 ± 278.5 vs 2952.8 ± 483) (p < 0.001). The yearly average of animal bites post-2011 was significantly greater than the average prior to 2011 (2260.5 ± 372.1 vs 1609.8 ± 217.9) (p < 0.001). The average number of vaccine doses per animal exposure was 2.4. Concerning PEP protocols, protocol A (2 and 3 doses) was indicated in 79% of animal exposures cases. From 2004 to 2018, a downward trend was noted for protocol A (r = - 0.29, p < 0.001) and an upward trend for protocol B (3 and 5 doses) (r = 0.687, p < 0.001). During our study period, 5 fatal cases of human rabies were declared. CONCLUSION: Rabies remains a major public health problem in Tunisia. The political dynamics had an impact on the health care system and rabies control. Preventive measures should be applied adequately to decrease the burden of this disease.

The wound severity of animal bite victims visiting rabies prevention clinics and the influencing factors in Central China: a cross-sectional investigation.

BACKGROUND: Animal bites are a major public health problem. The more serious the bite wound is, the higher the risk of developing rabies is. This study aimed to investigate the severity of wounds among animal bite victims and identify the influencing factors in Wuhan, China. METHODS: A cross-sectional study was conducted among 1015 animal bite victims visiting rabies prevention clinics. We performed a face-to-face interview to collect information on the exposure category of the bite wound, the type of the offending animal, exposure-to-risk situations, etc. Factors associated with exposure categories were identified by multivariate logistic regression analysis. RESULTS: Five hundred and sixty-four (55.57%) cases were category III exposures, 418 (41.18%) were category II exposures, and 33 (3.25%) were category I exposures. People who were hurt by their own domestic animals (odds ratio [OR] = 1.55, 95% confidence interval [CI]: 1.14-2.10), and those exposed to animals unvaccinated against rabies (OR = 1.45, 95% CI: 1.08-1.95) had a higher risk for category III exposures. Respondents who did not know the fatality of rabies were more likely to be injured seriously compared to those who knew that rabies is fatal, and the OR was 1.40 (95% CI, 1.05-1.86). CONCLUSIONS: This study showed that factors associated with the severity of bite wounds mainly included types of the offending animal, vaccination status of the animal, and knowledge of rabies fatality. Educational programs and awareness-raising campaigns should be provided to decrease severe animal bites, especially targeting pet owners and those with limited rabies knowledge.

The Geographic Distribution, Venom Components, Pathology and Treatments of Stonefish (Synanceia spp.) Venom.

Stonefish are regarded as one of the most venomous fish in the world. Research on stonefish venom has chiefly focused on the in vitro and in vivo neurological, cardiovascular, cytotoxic and nociceptive effects of the venom. The last literature review on stonefish venom was published over a decade ago, and much has changed in the field since. In this review, we have generated a global map of the current distribution of all stonefish (Synanceia) species, presented a table of clinical case reports and provided up-to-date information about the development of polyspecific stonefish antivenom. We have also presented an overview of recent advancements in the biomolecular composition of stonefish venom, including the analysis of transcriptomic and proteomic data from Synanceia horrida venom gland. Moreover, this review highlights the need for further research on the composition and properties of stonefish venom, which may reveal novel molecules for drug discovery, development or other novel physiological uses.
