Environmental factors associated with the prevalence of animal bites or stings in patients admitted to an emergency department

Climatic factors correlate with emergency visits due to animal injuries in Southern Turkey: A single-center retrospective study

BACKGROUND

Animal-related injuries are among the major causes of morbidity and mortality all over the world, especially in rural areas. This study aims to determine the characteristic features of animal-related injury cases presented to the emergency department and to evaluate their temporal trends and relationships with climatic factors.

METHODS

Among the animal-related injury cases, those who applied between January 1, 2017, and December 31, 2021, in a small seaside town in Turkey were included in the study. Application date, age, gender, ICD code, and prognosis constitute the variables from the hospital information management system within the relevant date range. Meteorological data were taken from Hatay Meteorological Directorate as average daily temperature ( °C) and humidity (g/m3). Descriptive statistics are presented using mean, standard error, number, percentage, and ratio. Kruskal-Wallis, Pearson correlation analysis, linear trend analysis, chi-square, and t-test were used in the analyses. The statistical significance level was accepted as p < 0.05.

RESULTS

A total of 6634 animal-related injuries were included in the study. The average age of the injured was 26.1 ± 21.1 years and 60.3 % were male. Injuries were most frequently observed in the 0-9 age group (29.9 %). Of all the cases, around 0.1 % were hospitalized and there were no reported deaths. Injuries caused by mammalian species accounted for 85 % of the cases. The number of recorded cases was lowest in 2018 and highest in 2021. Over the five years, animal-related injuries showed an increase trend which was not statistically significant (R2 = 0.216, p= 0.430). The injury cases showed a marked seasonality; numbers tended to increase in March and reached the highest level between June and September. While a significant and positive relationship was observed between the daily average temperature and the number of cases (r = 0.428, p < 0.001), there was no correlation between the average relative humidity and the injury numbers (p = 0.537).

CONCLUSION

This study revealed that animal-related injuries were commonly seen in children and young middle-aged adult groups and during warmer seasons. Based on the results of the study, we suggest several strategies to reduce the public health impact of animal-induced injuries, such as region-specific intervention programs adapted to animal species and seasonal changes, educational campaigns targeting children during the warmer seasons, and improved data recording systems for the cases.

Over half of known human pathogenic diseases can be aggravated by climate change

It is relatively well accepted that climate change can affect human pathogenic diseases; however, the full extent of this risk remains poorly quantified. Here we carried out a systematic search for empirical examples about the impacts of ten climatic hazards sensitive to greenhouse gas (GHG) emissions on each known human pathogenic disease. We found that 58% (that is, 218 out of 375) of infectious diseases confronted by humanity worldwide have been at some point aggravated by climatic hazards; 16% were at times diminished. Empirical cases revealed 1,006 unique pathways in which climatic hazards, via different transmission types, led to pathogenic diseases. The human pathogenic diseases and transmission pathways aggravated by climatic hazards are too numerous for comprehensive societal adaptations, highlighting the urgent need to work at the source of the problem: reducing GHG emissions.

Imposing COVID-19 lockdown and reported dog bite cases: An experience from a tertiary antirabies center of North India

The world was taken aback after the corona pandemic started from China and soon engulfed the whole of the world. Strict restrictions were in place since the beginning, and people were confined to their homes; only emergency services were allowed to work. The study's objectives were to see the effect of lockdown on the number of dog bite cases being reported to our antirabies clinic. The study was conducted in the antirabies clinic of the Department of Community Medicine, Government Medical College, Srinagar, Jammu & Kashmir. This study involved a dog bite victim who approached the said clinic during the lockdown, which was implemented in the wake of COVID-19 from March 21, 2020 to June 03, 2020. We included all the dog bite victims living in the Srinagar city and from the adjoining districts who had been bitten by the street dog during the lockdown phase. Over 5 years, 4,670 (73.6%) dog bites among males were reported. The proportion of dog bites among males varies from 72% to 81% in the 5 years. It can be observed that a maximum of 783 (81.1%) dog bites were reported from males during the lockdown period in 2020. Moreover, 2,847 (44.9%) bites were category II dog bites, while 3,392 (55.1%) were category III dog bites. There were fewer dog bites reported at the first, fourth, seventh, eighth, and ninth weeks while there was a little surge in cases on the 2nd, 3rd, 5th, 6th, and 10th week. Lockdown had indirectly reduced the number of dog bite cases reported to the clinic during different lockdown phases than the previous year's data.

Patients with centipede bites presenting to a university hospital in Bangkok: a 10-year retrospective study

INTRODUCTION

Centipede envenomation occurs commonly in tropical and subtropical countries. In most cases, centipede envenomation causes benign clinical manifestations. Serious complications are reported occasionally. Clinical studies regarding centipede envenomation are limited to case reports and case series. This study aimed to determine the prevalence and clinical characteristics of centipede bites in Bangkok, Thailand.

METHODS

This was a retrospective medical record review study. We included patients who were clearly envenomated by a centipede presenting to the emergency department of a tertiary university hospital in Bangkok from January 1, 2006, to December 31, 2015. Data were collected on demographics, details of the exposure, signs, symptoms, treatment, and complications of envenomation.

RESULTS

A total of 245 cases were included. The prevalence of centipede bite was 0.0367%. The majority were female (56.7%). The median age was 34.6 years (range: 1 month to 90 years). The number of envenomations was highest from October through December. Feet (38.3%) and hands (19.1%) were the parts of the body most often envenomated. Local effects were common with 99.5% of patients having localized pain and 87% having local swelling at the bite site. In terms of systemic effects, urticarial rash (5.7%) and fever (4.1%) were most frequently observed. Twelve cases (5%) had clinical pictures compatible with anaphylaxis. For pain management, all patients who had pain received analgesic drugs, while 29.7% were injected with local anesthesia. Antibiotics, antihistamines, and steroids were prescribed in 53.9%, 20.4%, and 10.2% of cases, respectively. No deaths occurred in this study.

CONCLUSIONS

Even though the location of our hospital is in a metropolitan city in Thailand, there were centipede bites every month, especially during the last three months of each year. Nearly all patients had local effects. In contrast, serious complications such as anaphylaxis and systemic infection only occurred occasionally.

Burden, risk factors, and infectious complications of cellulitis and erysipelas in US adults and children in the emergency department setting

BACKGROUND

Little is known about the use and burden of emergency department (ED) visits for cellulitis/erysipelas in the United States.

OBJECTIVE

To determine the prevalence, risk factors, complications, and cost of emergency care for cellulitis/erysipelas in the United States.

METHODS

Cross-sectional study of the 2006 to 2016 National Emergency Department Sample, including a 20% sample of US ED visits (N = 320,080,467).

RESULTS

The mean annual incidence of ED visits with a primary diagnosis of cellulitis/erysipelas was 2.42 to 3.55 per million adult and 1.14 to 2.09 per million pediatric ED visits. ED visits for cellulitis/erysipelas decreased significantly from 2006 to 2015 (Rao-Scott chi-square, P < .0001). ED visits with versus without a primary diagnosis of cellulitis/erysipelas were associated with public or no insurance and lower household income quartiles, and were more likely to occur during weekends and summer months. The mean cost of ED visits for cellulitis/erysipelas more than doubled in adults (from $720 to $1680) and tripled in children (from $939 to $2,823) from 2006 to 2016. ED visits for cellulitis/erysipelas were associated with multiple risk factors and increased infectious complications.

LIMITATIONS

No data on cellulitis and erysipelas treatment or recurrence.

CONCLUSION

There is a substantial and increasing burden of ED visits for cellulitis/erysipelas in the United States. Many ED visits occurred for uncomplicated cellulitis/erysipelas, in part because of health care disparities.
