Abstract
PURPOSE To review the neuro-ophthalmic manifestations of Lyme disease at a central Ohio pediatric tertiary care center. METHODS A retrospective chart review of patients diagnosed as having Lyme disease from September 2015 to September 2020 was completed. Demographic information, diagnosis dates, and manifestations of Lyme disease were recorded. Patients were excluded for age older than 18 years or lack of corroborated Lyme disease diagnosis. Descriptive statistics were performed. RESULTS Of the 212 cases of pediatric Lyme disease reviewed, 50 patients had neuroborreliosis. The data showed an increase in Lyme disease and neuroborreliosis cases from 2018 to 2020, with a preponderance of diagnoses in the summer months. Twenty-four patients had meningitis, and 6 of these patients (25%) were diagnosed as having bilateral optic disc edema that was clinically consistent with intracranial hypertension. CONCLUSIONS Papilledema in the setting of Lyme meningitis may be more common than previously reported in central Ohio. If Lyme disease meningitis is suspected, an opening pressure should be recorded at the time of lumbar puncture and, if elevated, an ophthalmologic evaluation for optic nerve edema is indicated.

Schols R, Smitz N, Vanderheyden A, Huyse T. Expanding the swimmer's itch pool of the Benelux: a first record of the neurotropic Trichobilharzia regenti and potential link to human infection. Parasit Vectors 2024; 17:126. [PMID: 38481352 PMCID: PMC10938770 DOI: 10.1186/s13071-024-06218-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Accepted: 02/27/2024] [Indexed: 03/17/2024] Open
Abstract
BACKGROUND Swimmer's itch, an allergic contact dermatitis caused by avian and mammalian blood flukes, is a parasitic infection affecting people worldwide. In particular, avian blood flukes of the genus Trichobilharzia are infamous for their role in swimmer's itch cases. These parasites infect waterfowl as a final host, but incidental infections by cercariae in humans are frequently reported. Upon accidental infections of humans, parasite larvae will be recognized by the immune system and destroyed, leading to painful itchy skin lesions. However, one species, Trichobilharzia regenti, can escape this response in experimental animals and reach the spinal cord, causing neuroinflammation. In the last few decades, there has been an increase in case reports across Europe, making it an emerging zoonosis. METHODS Following a reported case of swimmer's itch in Kampenhout in 2022 (Belgium), the transmission site consisting of a private pond and an adjacent creek was investigated through a malacological and parasitological survey. RESULTS Six snail species were collected, including the widespread Ampullaceana balthica, a well-known intermediate host for Trichobilharzia parasites. Shedding experiments followed by DNA barcoding revealed a single snail specimen to be infected with T. regenti, a new species record for Belgium and by extension the Benelux. Moreover, it is the most compelling case to date of the link between this neurotropic parasite and cercarial dermatitis. Additionally, an Echinostomatidae sp. and Notocotylus sp. were isolated from two other specimens of A. balthica. However, the lack of reference DNA sequences for these groups in the online repositories prevented genus- and species-level identification, respectively. CONCLUSIONS The presence of T. regenti in Belgium might have severe clinical implications and its finding highlights the need for increased vigilance and diagnostic awareness among medical professionals. The lack of species-level identification of the other two parasite species showcases the barcoding void for trematodes. Overall, these findings demonstrate the need for a Belgian framework to rapidly detect and monitor zoonotic outbreaks of trematode parasites within the One Health context.

Abstract
OBJECTIVES This study aimed to explore the published research on the relationship between climate change and skin cancer and the implications for prevention, management and further research. STUDY DESIGN Scoping review. METHODS This scoping review following JBI methodology reviewed English articles identified in searches of MEDLINE, Embase, CINAHL, Web of Science and Scopus on 14 April 2023. The screening of articles was completed by two independent reviewers. Data were extracted by a single reviewer and checked by another. A causal pathway diagram was iteratively developed throughout the review and was used to categorise the findings. RESULTS The search identified 1376 papers, of which 45 were included in the final review. Nine papers reported primary research, and 36 papers were reviews, perspectives, commentaries, editorials, or essays. The papers examined climate change influencing behaviours related to ultraviolet exposure (30 papers), ambient temperature (21 papers) and air pollution (five papers) as possible risk factors; occupational, rural, and contextual factors affecting skin cancer (11 papers); and prevention and access to health care in the context of climate change (seven papers). Most papers were published in journals in subject areas other than health. CONCLUSIONS This review identified ultraviolet radiation, occupation, rising temperature, individual behaviour and air pollution as possible influences on skin cancer rates. Furthermore, it highlights the complexity and uncertainties in the relationship between climate change and skin cancer and the need for further research on this relationship, including primary epidemiological research and reviews that follow recognised review guidelines and include assessment of health services and social determinants in the causal pathways of this relationship.

Abstract
Importance The US health care system generates substantial global waste. Skin biopsies are frequently performed by dermatologists and represent a practical and scalable opportunity for waste reduction interventions in dermatology clinics. Objective To develop and implement a systematic framework for decreasing skin biopsy tray waste in dermatology clinics. Design, Setting, and Participants This quality improvement study was conducted at 4 outpatient clinic sites within a single institution between October 2021 and April 2022. The clinic site with the greatest skin biopsy tray waste production was selected for intervention. Waste audits before and after the intervention quantified the number of wasted supplies per skin biopsy tray in dermatology clinics. The participants were dermatology residents, faculty, nurses, medical assistants, and clinic managers. Interventions Provision of educational materials about climate change and health care and standardizing biopsy tray setup to decrease wasted supplies. Main Outcomes and Measures Quantity of wasted skin biopsy tray supplies (gauze squares, alcohol pads, cotton swabs, and adhesive bandages) before and after interventions. Results In waste audits in 4 outpatient dermatology clinics (comprising 98 skin biopsy trays), prior to intervention, 100% of skin biopsy trays had more than 2 wasted supplies within targeted outpatient dermatology clinics at the Stanford Cancer Institute with a mean (SD) of 10.1 (3.4) wasted items per biopsy tray. Following the quality improvement-based interventions, only 16% of skin biopsy trays had more than 2 wasted supplies and the mean (SD) number of wasted supplies per tray decreased to 1.6 (1.3). Conclusions and Relevance Results of this quality improvement study suggest that through collaboration with all members of the clinical team including physicians, medical assistants, nurses, and clinic managers, skin biopsy tray setup modifications may be associated with reduced waste in outpatient dermatology clinics. This study presents a framework that accounts for different factors in the production of waste in individual clinic settings, and thus can be adapted within additional dermatology clinics.

Abstract
Climate change, fueled by increasing concentrations of greenhouse gases, is associated with rising temperatures, extreme weather events, increased aeroallergen production, and air pollution. Our understanding that many inflammatory cutaneous diseases carry important mental health comorbidities is expanding. Simultaneously, the detrimental impacts of climate change on human health are now widely recognized as a global public health crisis. Importantly, these climate-associated phenomena exacerbate the environmental triggers of atopic dermatitis (AD) and are also associated with amplification of comorbid mental health conditions in AD including depression, anxiety, trauma-related disorders, and psychotic spectrum disorders. This review is the first to examine the nexus of climate change, atopic dermatitis, and mental health comorbidities and emphasizes the disproportionate impacts of climate change in vulnerable and marginalized populations.

Abstract
In medical mycology, the main context of disease is iatrogenic-based disease. However, historically, and occasionally, even today, fungal diseases affect humans with no obvious risk factors, sometimes in a spectacular fashion. The field of “inborn errors of immunity” (IEI) has deduced at least some of these previously enigmatic cases; accordingly, the discovery of single-gene disorders with penetrant clinical effects and their immunologic dissection have provided a framework with which to understand some of the key pathways mediating human susceptibility to mycoses. By extension, they have also enabled the identification of naturally occurring auto-antibodies to cytokines that phenocopy such susceptibility. This review provides a comprehensive update of IEI and autoantibodies that inherently predispose humans to various fungal diseases.

Short-term effect of ambient temperature and ambient temperature changes on the risk of warts outpatient visits in Hefei, China: a retrospective time-series study. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:19342-19355.

Abstract
Concerns are growing about the adverse health effects of ambient temperature and ambient temperature changes. However, the association between ambient temperature and ambient temperature changes on the risk of warts outpatient visits is poorly understood. Our study used the distributed lag non-linear model (DLNM) aimed to evaluate the association between ambient temperature, ambient temperature changes (including temperature change between neighboring days (TCN) and diurnal temperature range (DTR)), and warts outpatient visits. We also performed subgroup analyses in order to find susceptible populations by gender and age groups. The maximum relative risk (RR) of low ambient temperature (0 °C) for warts outpatient visits was 1.117 (95% CI: 1.041-1.198, lag 04 days), and the maximum RR of high ambient temperature (32 °C) for warts outpatient visits was 1.318 (95% CI: 1.083-1.605, lag 07 days). The large temperature drop (TCN = - 3 °C) decreased the risk of warts visits, with the lowest RR value at the cumulative exposure of lag 7 days (RR = 0.888, 95% CI: 0.822-0.959), and the large temperature rise (TCN = 2 °C) increased the risk of warts visits, with the highest RR value at the cumulative exposure of lag 7 days (RR = 1.080, 95% CI: 1.022-1.142). Overall, both low and high ambient temperatures and large temperature rise can increase the risk of warts visits, while large temperature drop is a protective factor for warts visits. However, we did not find any association between DTR and warts visits. Furthermore, subgroup analyses showed that males and the young (0-17 years old) were more sensitive to low and high ambient temperatures, and the elderly (≥ 65 years old) were more susceptible to TCN. The results may provide valuable evidence for reducing the disease burden of warts in the future.

Abstract
In this article, we discuss pertinent cutaneous findings with which patients may present after travel to tropical destinations. We address arthropod-borne infectious diseases such as cutaneous leishmaniasis, Chagas disease, cutaneous larva migrans, and myiasis. We discuss other relevant diseases with cutaneous signs such as monkey pox and severe acute respiratory syndrome coronavirus 2. We provide clinicians with information regarding the background, diagnosis, treatment, and prevention of these tropical rashes. In addition, we address the impact that climate change will have on the temporal and geographic incidence of these rashes. Viral, fungal, and vector-borne diseases have seen a geographic expansion into more northern latitudes. Among these are tick-borne Lyme disease, aquatic snail-related seabather's eruption, and atopic dermatitis. As these diseases spread, we believe that the updated information within this article is significant to the practicing physician in today's warming world.

Abstract
Background: The amount of data available online is constantly increasing, including search behavior and tracking trends in domains such as Google. Analyzing the data helps to predict patient needs and epidemiological events more accurately. Our study aimed to identify dermatology-related terms that occur seasonally and any search anomalies during the SARS-CoV-2 pandemic. Methods: The data were gathered using Google Trends, with 69 entries between January-2010 and December-2020 analyzed. We conducted the Seasonal Mann–Kendal Test to determine the strength of trends. The month with the highest seasonal component (RSV) and the lowest seasonal component (RSV) was indicated for every keyword. Groups of keywords occurring together regularly at specific periods of the year were shown. Results: We found that some topics were seasonally searched in winter (e.g., herpes, scabies, candida) and others in summer (e.g., erythema, warts, urticaria). Conclusions: Interestingly, downward trends in searches on sexually transmitted diseases in comparison with increased infection rates reported officially show a strong need for improved sexual education in Poland. There were no significant differences in trends for coronavirus-related cutaneous symptoms during 2020. We have shown that the seasonality of dermatologically related terms searched in Poland via Google did not differ significantly during SARS-CoV-2 pandemic.

INTERNATIONAL JOURNAL OF BIOMETEOROLOGY 2022; 66:1487-1493. [PMID: 35522347 DOI: 10.1007/s00484-022-02297-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2021] [Revised: 04/06/2022] [Accepted: 04/26/2022] [Indexed: 06/14/2023]
Abstract
The effect of ambient temperature on dermatologic diseases has received widespread attention. Previous studies have shown that ambient temperature might affect specific dermatologic diseases, but results were inconsistent. This study aims to assess the short-term effect of ambient temperature on outpatient visits due to dermatologic diseases (DMs) in Xinxiang, China. Daily DMs outpatient visits, mean temperature, mean relative humidity, and air pollution data of Xinxiang were retrieved from January 1, 2015, to December 31, 2018. A distributed lag nonlinear model (DLNM) was applied to analyze the effect of ambient temperature on DMs outpatients. We controlled several potential confounding factors such as the long-term trend, public holiday, day of the week, humidity, and air pollutants (NO2, PM2.5). Finally, two more stratification analysis was conducted by age and gender. A total of 164,270 outpatients of DMs were enrolled during our study, and the daily mean visits were 113. The estimated effect of temperature on DMs was nonlinear. Heat temperature would exacerbate outpatients of dermatologic diseases. With a reference median temperature (17 °C), the effect of temperature on DMs was most pronounced at lag0-14; exposure to heat (32 °C, 99th) was associated with 1.565 (95% CI: 1.266-1.934) increased risk of outpatients for DMs. Stratification analysis showed that citizens of young ages were susceptive to heat; both genders had a similar relationship between temperature and DMs risk. This study highlights that ambient temperature was associated with DMs outpatients; heat temperature might aggravate DMs risk. The health hazards of heat temperature required more attention, and more effective prevention measurements should be designed and implemented to curb global warming.

Abstract
Human cercarial dermatitis (HCD) caused by avian schistosomes is an emerging health issue in different parts of the world. Nevertheless, parasite diversity, life cycle, and involvement in HCD remain poorly known or neglected in South America. Herein, we reported data obtained during a long-term malacological survey carried out in Pampulha Reservoir, an urban eutrophic waterbody from Brazil between 2009 and 2012. An ocellate brevifurcate cercaria emerged from 55 of 16,235 (0.34%) specimens of Biomphalaria straminea. Samples of the cercariae were subjected to morphological, experimental, and molecular study (analysis of partial sequences of nuclear 28S and mitochondrial cox1 genes). The molecular analysis revealed that the larva corresponds to an avian schistosome; however, it does not correspond to any named genus. A close related isolate was previously reported in Biomphalaria sudanica from Kenya (molecular divergences of 0.54% and 9.62% for 28S and cox1, respectively). The morphology of this cercaria was compared with other avian schistosome larvae from Biomphalaria spp. Attempts to infect experimentally ducks (Cairina moschata) and mice revealed cutaneous manifestations after exposure to cercariae, but adult parasites were not obtained in these hosts. Phylogenetic analysis suggests this parasite is a putative new genus and species of avian schistosome. The potential involvement of the larvae herein described in cases of HCD in Brazil cannot be ruled out. Surprisingly, HCD was not reported in the country so far, which can be related to difficulties in its diagnosis in areas of overlap with human schistosomes.

Abstract
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.

Abstract
Pediatric populations are expected to bear most of the climate change impacts, with racial minorities and children living in poorer countries being particularly vulnerable. Given their relevance to cutaneous disease, dermatologists should be aware of these climate-sensitive health impacts and the ways in which they intersect with social factors. Strategies including targeted risk communication, motivational interviewing, and storytelling can help facilitate climate discussions during the patient encounter. In this article the authors summarize common dermatologic health impacts related to environmental exposures and provide sample scripts for climate messaging.

Abstract
Climate change, exemplified by higher average global temperatures resulting in more frequent extreme weather events, has the potential to significantly impact human migration patterns and health. The consequences of environmental catastrophes further destabilize regions with pre-existing states of conflict due to social, political, and/or economic unrest. Migrants may carry diseases from their place of origin to their destinations and once there may be susceptible to diseases in which they had not been previously exposed to. Skin diseases are among the most commonly observed health conditions observed in migrant populations. To improve awareness among dermatologists of the burden of skin diseases among migrants, the group searched the English language scientific literature to identify articles linking climate change, migration, and skin disease. Skin diseases associated with human migration fall into three major categories: (i) communicable diseases, (ii) noncommunicable diseases, and (iii) environmentally mediated diseases. Adopting comprehensive global strategies to improve the health of migrants requires urgent attention.

Abstract
In 2017, health and social care organizations contributed 6.3% of carbon emissions in England. Efforts to reduce the environmental footprint of the National Health Service (NHS) have been broadly focused on reducing demand, through prevention and patient empowerment, and modifying supply side factors by focusing on lean care systems and low carbon alternatives. This narrative review concentrates on supply side factors to identify sustainable practices with a focus on actions that could be implemented in dermatology departments. For this study, a literature review was conducted In MEDLINE in April 2020. The search terms included 'environmental sustainability' and 'climate change' with 'dermatology', 'telemedicine', 'NHS', 'surgery' and 'operating theatres'. Out of 95 results, 20 were deemed relevant to the review. Although the review showed that there is clearly growing interest in environmental sustainability, the identified literature lacked examples of comprehensive implementation and evaluation of initiatives. The literature discussed distinct areas including transport, waste management and procurement as part of a lean healthcare system. A number of papers highlighted the potential contribution of carbon-reducing actions without citing verifiable outcome data. This narrative review highlights the need for detailed environmental impact assessments of treatment options in dermatology, in tandem with economic analysis. In conclusion, we have identified a clear need for evidence-based guidance setting out implementable actions with identifiable benefits achievable within local clinical teams. This will require engagement between clinicians, patients and healthcare organizations.

Abstract
Anthropogenic global climate change is a well-documented phenomenon that has led to average global temperatures climbing to approximately 1 °C above preindustrial (1850-1900) levels, with even higher regional deviations in some areas and significantly increased average warming in densely populated urban centers. In 2018, the United Nations Intergovernmental Panel on Climate Change set a threshold of 1.5 °C of average warming (above the preindustrial baseline), beyond which our planet will become significantly less hospitable to human life. However, adverse human health impacts are already occurring due to current levels of global climate change, as summarized by publications such as The Lancet's annual "Countdown on Health and Climate Change," initiated in 2016. The human health impacts of climate change are truly cross-disciplinary, with nearly every medical specialty either already facing or set to face effects. The field of dermatology is not immune to these risks. This special issue of the International Journal of Women's Dermatology is dedicated to the cross section of dermatology and climate change. This initial article will serve as an overview to introduce readers to the topic and to lay the groundwork for the rest of the issue. We are delighted to work with the Women's Dermatological Society and welcome their support for this dedicated issue. Herein, you will read from up-and-coming stars in the field and established experts, including articles on the following key areas: infectious diseases, environmentally friendly office practices, sunscreens and the environment, refugee health, heat-related illness, the effect of air pollution on the skin, the impact of climate change on pediatric dermatology, implications for skin cancer, and skin issues related to flooding and extreme weather events.

Abstract
The acute impact of climate change on human health is receiving increased attention, but little is known or appreciated about the effect of climate change on chronic diseases, particularly cancer. This Review provides a synopsis of what is known about climate change and the exposures it generates relevant to cancer. In the context of the world's cancer burden and the probable direction we could expect to follow in the absence of climate change, this scoping review of the literature summarises the effects that climate change is having on major cancers, from environmental exposures to ultraviolet radiation, air pollution, disruptions in the food and water supply, environmental toxicants, and infectious agents. Finally, we explore the effect of climate change on the possible disruption of health systems that have been essential to cancer control practice. We conclude with potential responses and opportunities for intervention.

Abstract
Climatological research over the past two decades makes it clear that the Earth's climate will change. Climate change has many, mostly adverse, effects on the human health. Environmental anthropogenic changes represent significant health risks including factors that may increase probability and seriousness of skin cancer diseases. There are many scientific studies on skin cancer but only a few of them are focused on environment changes and their influence on the behaviour of humans, which may lead to skin cancer. The goal of the research was to analyse environment changes in the city of Brno (Czech Republic) and their influence on the behaviour of people and some skin diseases. A research hypothesis was set up that total increase in the incidence of skin diseases would be monitored. 1757 patients aged 25-65 years participated in the research. The analysis was performed based on measured (mean annual temperatures, average monthly temperatures, ultraviolet index values, and numbers of sunny days and sunny hours) data in 2011-2019. In order to monitor the trend, temperature data from 1961 to 2019 were evaluated too. The analysed data indicate that the trend of average monthly and annual temperatures observed was increasing in recent years. Moreover, based on data obtained from the analysed doctor's office it was found out that the incidence of skin diseases increased in the studied period. The main reasons to increase include excessive exposure to sun, extended average age of the population, ozone layer depletion, climatic and weather changes, increased migration and behaviour of people.

Abstract
Coccidioidomycosis is an endemic mycosis of the southern United States, Northern Mexico, and South America. Primary cutaneous coccidioidomycosis, despite being a very rare clinical presentation, has shown an increasing incidence. An extensive literature search for cutaneous coccidioidomycosis cases was performed using the OLDMEDLINE, PubMed, Cochrane, LILACS and Google Scholar databases for studies published from January 1927 through December 21, 2019. Forty-two observational studies were included totaling 82 cases of primary cutaneous coccidioidomycosis. Narrative reviews, systematic reviews, and meta-analyses were also included. Additionally, an original case was included. Patients with primary cutaneous coccidioidomycosis share the same geographical and epidemiological characteristics as those with pulmonary or disseminated coccidioidomycosis. Most of the imported cases came from endemic areas. A large portion of cases had prior local skin trauma. Tissue culture is still the leading diagnostic method; nevertheless, molecular techniques such as polymerase chain reaction (PCR) are currently relevant to differentiate between species. First-line treatment consists of azoles; however, it has an excellent prognosis even without treatment. Primary cutaneous coccidioidomycosis should be considered a differential diagnosis of unusual infections or neoformations in any part of the body in resident populations of endemic areas or in patients with a previous history of travel to these areas.

Abstract
Purpose of Review Climate change represents a major existential threat facing the global community, and it has already begun to affect human health in a multitude of ways. This review highlights and discusses the implications that climate change has already had and is expected to have for inpatient dermatologists. Recent Findings There are a variety of conditions affected by climate changes. The distribution and frequencies of infectious diseases and their vectors are changing in line with variations in climate conditions. Increased temperatures have already been associated with exacerbation of existing skin conditions, such as atopic dermatitis, and recent evidence suggests that higher temperatures will also magnify the effects of harmful ultraviolet radiation. Extreme weather events that result from climate change are followed by an array of dermatologic conditions that may be unusual for the given location. Inpatient dermatologists should be prepared to manage these potentially unfamiliar dermatologic consequences of climate change. Summary Climate change will have widespread effects on the medical field, and inpatient dermatologists will be faced with their own unique set of challenges and practice variations. Practitioners should be familiar with the ongoing and predicted effects of climate change in their locations so that they can readily identify and treat associated conditions, and they should adjust their practice to reduce their carbon footprint and serve as a model for patients to do the same.

Abstract
OBJECTIVE To analyze the correlation between climatic factors and the incidence of varicella in Guangzhou, and improve the prevention measures about public health. METHODS Data for daily climatic variables and varicella incidence from 2006 to 2018 in Guangzhou were collected from the Guangzhou Meteorological Bureau and the National Notifiable Disease Report System. Distributed lag nonlinear models were applied to evaluate the association between climatic factors and varicella incidence. RESULTS The nonlinear effects of meteorological factors were observed. At lag day21,when the mean temperature was 31.8 °C, the relative risk was the highest as 1.11 (95% CI: 1.07-1.16). When the diurnal temperature range was 24.0 °C at lag day 20, the highest RR was 1.11 (95% CI: 1.05-1.17). For rainfall, the highest RR was 1.09 (95% CI: 1.01-1.19) at lag day 21,when the aggregate rainfall was 160 mm. When air pressure was 1028 hPa, the highest RR was 1.08 (95% CI: 1.04-1.13) at lag day 21. When wind speed was 0.7 m/s, the highest RR was 1.07 (95% CI: 1.04-1.11) at lag day 7. When the hours of sunshine were 9.0 h at lag day 21, the RR was highest as 1.04 (95% CI: 1.02-1.05). Aggregate rainfall, air pressure, and sunshine hours were positively correlated with the incidence of varicella, which was inconsistent with the wind velocity. Mean temperature showed a reverse U-shape curve relationship with varicella, while the diurnal temperature range showed a binomial distribution curve. The extreme effect of climatic factors on the varicella cases was statistically significant, apart from the extremely low effect of rainfall. CONCLUSION Our preliminary results offered fundamental knowledge which might be benefit to give an insight into epidemic trends of varicella and develop an early warning system. We could use our findings about influential factors to strengthen the intervention and prevention of varicella.

Abstract
Biological effects have been reproducibly reported in rodents exposed to radiofrequency fields (RF) without significant change of the body temperature. These observations relaunch the controversial question of non-thermal effects of RF. If true, such effects would imply to consider RF energy absorption/interaction in tissues, not as volume-averaged, but locally down to the microscale, which is of potential consequence in particular at frequencies beyond 3 GHz. We propose study protocols to explore that question.

Abstract
Mumps, a common childhood disease, has a high incidence in Guangzhou city, China. It has been proven that mumps is influenced by seasonality. However, the role of meteorological factors among children is yet to be fully ascertained. This study explored the association between meteorological factors and the incidence of mumps among children in Guangzhou. Distributed lag nonlinear models were used to evaluate the correlation between meteorological factors and the incidence of mumps among children from 2014–2018. The nonlinear lag effects of some meteorological factors were detected. Mean temperature, atmospheric pressure, and relative humidity were positively correlated with mumps incidence, contrary to that of wind speed. Extreme effects of temperature, wind speed, atmospheric pressure, and relative humidity on the incidence of mumps among children in Guangzhou were evaluated in a subgroup analysis according to gender and age. Our preliminary results offered fundamental information to better understand the epidemic trends of mumps among children to develop an early warning system, and strengthen the intervention and prevention of mumps.

Abstract
Skin cancer is a non-communicable disease that has been underexplored in Africa, including Southern Africa. Exposure to solar ultraviolet radiation (UVR) is an important, potentially modifiable risk factor for skin cancer. The countries which comprise Southern Africa are Botswana, Lesotho, Namibia, South Africa, and Swaziland. They differ in population size and composition and experience different levels of solar UVR. Here, the epidemiology and prevalence of skin cancer in Southern African countries are outlined. Information is provided on skin cancer prevention campaigns in these countries, and evidence sought to support recommendations for skin cancer prevention, especially for people with fair skin, or oculocutaneous albinism or HIV-AIDS who are at the greatest risk. Consideration is given to the possible impacts of climate change on skin cancer in Southern Africa and the need for adaptation and human behavioural change is emphasized.

Abstract
Climate change is associated with shifts in global weather patterns, especially an increase in ambient temperature, and is deemed a formidable threat to human health. Skin cancer, a non-communicable disease, has been underexplored in relation to a changing climate. Exposure to solar ultraviolet radiation (UVR) is the major environmental risk factor for skin cancer. South Africa is situated in the mid-latitudes and experiences relatively high levels of sun exposure with summertime UV Index values greater than 10. The incidence of skin cancer in the population group with fair skin is considered high, with cost implications relating to diagnosis and treatment. Here, the relationship between skin cancer and several environmental factors likely to be affected by climate change in South Africa are discussed including airborne pollutants, solar UVR, ambient temperature and rainfall. Recommended strategies for personal sun protection, such as shade, clothing, sunglasses and sunscreen, may change as human behaviour adapts to a warming climate. Further research and data are required to assess any future impact of climate change on the incidence of skin cancer in South Africa.

Short-Term Effects of Meteorological Factors and Air Pollutants on Hand, Foot and Mouth Disease among Children in Shenzhen, China, 2009-2017. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16193639. [PMID: 31569796 PMCID: PMC6801881 DOI: 10.3390/ijerph16193639] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/28/2019] [Revised: 09/12/2019] [Accepted: 09/23/2019] [Indexed: 12/20/2022]
Abstract
BACKGROUND A few studies have explored the association between meteorological factors and hand, foot, and mouth disease (HFMD) with inconsistent results. Besides, studies about the effects of air pollutants on HFMD are very limited. METHODS Daily HFMD cases among children aged 0-14 years in Shenzhen were collected from 2009 to 2017. A distributed lag nonlinear model (DLNM) model was fitted to simultaneously assess the nonlinear and lagged effects of meteorological factors and air pollutants on HFMD incidence, and to further examine the differences of the effect across different subgroups stratified by gender, age and childcare patterns. RESULTS The cumulative relative risk (cRR) (median as reference) of HFMD rose with the increase of daily temperature and leveled off at about 30 °C (cRR: 1.40, 95%CI: 1.29, 1.51). There was a facilitating effect on HFMD when relative humidity was 46.0% to 88.8% (cRR at 95th percentile: 1.18, 95%CI: 1.11, 1.27). Short daily sunshine duration (5th vs. 50th) promoted HFMD (cRR: 1.07, 95%CI: 1.02, 1.11). The positive correlation between rainfall and HFMD reversed when it exceeded 78.3 mm (cRR: 1.41, 95% CI: 1.22, 1.63). Ozone suppressed HFMD when it exceeded 104 µg /m3 (cRR at 99th percentile: 0.85, 95%CI: 0.76, 0.94). NO2 promoted HFMD among infants and the cRR peaked at lag 9 day (cRR: 1.47, 95%CI: 1.02, 2.13) (99th vs. 50th). Besides, children aged below one year, males and scattered children were more vulnerable to high temperature, high relative humidity, and short sunshine duration. CONCLUSIONS Temperature, relative humidity, sunshine duration, rainfall, ozone and NO2 were significantly associated with HFMD, and such effects varied with gender age and childcare patterns. These findings highlight the need for more prevention effort to the vulnerable populations and may be helpful for developing an early environment-based warning system for HFMD.

Abstract
Skin is the body's first line of defense against invading microorganisms. The skin microbiome has been shown to provide immunity against exogenous bacterial colonization. Recreational water exposures may alter the skin microbiome and potentially induce skin infections. This study explored the link between ocean water exposures and the human skin microbiome. Skin microbiome samples were collected, using swabs, from human participants' calves before and after they swam in the ocean, and at 6 hour and 24 hour post-swim. Genomic analysis showed that skin microbiomes were different among individuals before swimming. But after swimming, microbial communities were no longer different, which was demonstrated by a decrease in inter-sample diversity. Taxonomic analysis showed that ocean bacteria, including potential pathogens, replaced the native skin bacteria and remained on the skin for at least 24 hour post-swim. This research provides insight into the relationship between the human skin microbiome and the environment.

Abstract
The October 2018 report from the United Nations Intergovernmental Panel on Climate Change predicts significant threats to human health secondary to anthropogenic global warming; children have been and will continue to be disproportionately affected by these weather-related changes. Multiple physician groups have acknowledged climate change as a public health issue, calling upon providers to educate their communities about this looming health crisis while also reducing their individual carbon footprints. A significant body of literature has also documented the adverse dermatologic consequences of a warmer planet, highlighting the importance of pediatric dermatologists in addressing climate change. Here, we summarize the rationale for the pediatric dermatologist as public health advocate, providing specific actionable items through which our specialty can positively address the climate change crisis and in turn protect the health of our patients now and in the future.

Abstract
Climate change contributes to the increase in severity and frequency of flooding, which is the most frequent and deadly disaster worldwide. Flood-related damage can be very severe and include health effects. Among those health impacts, dermatological diseases are one of the most frequently encountered. Both infectious and noninfectious dermatological conditions are increasing after flooding. We searched PubMed using the search term climate change OR global warming OR rainfall OR flooding OR skin. Articles published in the English-language literature were included. We also searched the International Society of Dermatology website library on climate change for additional articles. There is an increased risk of trauma during the course of a natural disaster. The majority of post-tsunami wound infections were polymicrobial, but gram-negative bacteria were the leading causes. Infectious diseases with dermatological manifestations, such as impetigo, leptospirosis, measles, dengue fever, tinea corporis, malaria, and leishmaniasis, are important causes of morbidity among flood-afflicted individuals. Insect bites and stings, and parasite infestations such as scabies and cutaneous larva migrans are also frequently observed. Inflammatory conditions including irritant contact dermatitis are among the leading dermatological conditions. Dermatological conditions such as alopecia areata, vitiligo, psoriasis, and urticaria can be induced or exacerbated by psychological conditions post disaster. Prevention is essential in the management of skin diseases because of flooding. Avoiding exposure to contaminated environments, wearing protective devices, rapid provision of clean water and sanitation facilities, prompt vector controls, and education about disease risk and prevention are important.

Abstract
Hand, foot and mouth disease (HFMD) and herpangina (HA) are common childhood diseases mostly associated with human enteroviruses (EV). Although usually benign illnesses, neurological complications may be observed during large epidemics when enterovirus A71 (EV-A71) is involved, as observed in the Asia Pacific Region and in China since the late 1990s. The occurrence of these complications warrants reinforcing the surveillance of the emergence of EV-A71 infections in France and Europe. Monitoring EV infections associated with HFMD can be considered as an effective tool to detect an upsurge of EV-A71 infections in a timely manner. In 2014, a national sentinel surveillance system for HFMD/HA was set up in France through a network of volunteer pediatricians and coordinated by the National Reference Center for Enteroviruses and Parechoviruses. Although classical manifestations of HFMD/HA can be easily recognized, there are several atypical presentations of the disease that can be confused with other skin conditions. Delayed cutaneous manifestations, such as onychomadesis and acral desquamation, may also occur and should prompt consideration of HFMD in the preceding weeks. Severe complications following HFMD include neurological manifestations (mainly rhombencephalitis) or less frequently cardiopulmonary failure and can sometimes be fatal. In China, the case severity rate has been estimated at 1%, with a case fatality rate at 0.03%. EV-A71 was involved in more than 90% of the fatal cases. Diagnosis of EV infections associated with severe neurological manifestations is based on the molecular detection of the EV genome in vesicles, cerebrospinal fluid (CSF), throat and stool given that EV-A71 is rarely recovered from the CSF. Positive EV genome detection should be followed by EV genotyping to identify the type of the EV. In temperate-climate countries, outbreaks of HFMD occur mostly but not exclusively during summer and autumn months. Adults may also present with HFMD. In 2016, an upsurge of severe neurological manifestations was reported in France; EV-A71 accounted for 50% of the cases. No specific treatment is available, but two inactivated EV-A71 vaccines are currently available in China.

Abstract
Spirochetes are a major threat to public health. However, the exact pathogenesis of spirochetal diseases remains unclear. Spirochetes express lipoproteins that often determine the cross talk between the host and spirochetes. Lipoproteins are pro-inflammatory, modulatory of immune responses, and enable the spirochetes to evade the immune system. In this article, we review the modulatory effects of spirochetal lipoproteins related to immune evasion. Understanding lipoprotein-induced immunomodulation will aid in elucidating innate pathogenesis processes and subsequent adaptive mechanisms potentially relevant to spirochetal disease vaccine development and treatment.
