Trips Through the Skin: Reviewing Cutaneous Drug Reactions to Psychedelics and Hallucinogens.

Although psychedelic and hallucinogenic substances have gained popularity for therapeutic use, their dermatologic adverse effects are poorly characterized. This review characterizes the cutaneous reactions associated with psychedelic and hallucinogenic drugs. A review of PubMed and Scopus was conducted from the inception of databases to August 31, 2023. Search terms included drug names and classes (cannabis, MDMA, ecstasy, 3,4-methylenedioxymethamphetamine, psychedelics, hallucinogens, peyote, marijuana, lysergic acid diethylamide, LSD, ketamine, dimethyltryptamine, DMT, phencyclidine, PCP, dextromethorphan, psilocybin, and ayahuasca), and dermatosis terms (dermatitis, contact dermatitis, drug eruption, skin reaction, and urticaria). Studies were included if there was an association with a psychedelic or hallucinogenic and any cutaneous reaction; studies without both components were excluded. Twenty-two studies met inclusion criteria, describing reactions to cannabis (10 studies), MDMA (5 studies), ketamine (4 studies), and psilocybin (3 studies). Forty total patients were included. Among cannabis-related reactions, the most common reaction was type I hypersensitivity by topical exposure (n = 21). Three patients reported type IV hypersensitivity reactions to contact with cannabis or cannabis-derived oils, all of whom experienced vesicular contact dermatitis. Two additional patients presented with an erythema-multiforme-like reaction and acute generalized exanthematous pustulosis after systemic administration, respectively. MDMA was associated with acneiform eruptions (2 cases), an urticarial eruption, a guttate psoriasis-like reaction, a fixed drug eruption, and Stevens-Johnson syndrome (1 case). Four patients reported type I hypersensitivity reactions to ketamine. Four patients reported vesicular eruptions, cyanosis, or widespread jaundice to psilocybin. Of the cases, 8 patients had cutaneous reactions that resolved with drug cessation, 10 resolved with cessation plus treatment, and resolution in 7 cases was not reported. Zero studies were found describing other psychedelic or hallucinogenic compounds. Further research is required to characterize reactions and treatments linked to the variety of extant psychedelics and hallucinogens.

Characteristics of Litigations Involving Contact Dermatitis: An Exploratory Analysis.

Background: Contact dermatitis (CD) is one of the most common skin disorders, occurring in >20% of patients worldwide. Estimated cost burden for CD in the United States approaches $1 billion annually. Objective: To describe characteristics of litigation among patients with CD. Methods: Westlaw legal database for U.S. lawsuits was queried for lawsuits between the years 1983 and 2021 containing the keywords "dermatitis or eczema." Each lawsuit associated with CD was analyzed by plaintiff demographics, verdict, prosecution reason, payouts, and allergen implicated. Results: Of 98 cases, 61 met the inclusion criteria. Verdicts issued favored plaintiffs (42.6%) more than defendants (32.8%) with the remaining cases decided through settlements. If payout occurred, the mean was $246,310 (standard deviation [SD] = $798,536), the median was $20,000 (Q1 = $8,500, Q3 = $88,725, interquartile range = $80,225). The top reason for litigation was toxic exposure (n = 38, 62.2%), and common contact allergens associated with lawsuits were latex (n = 4, 20%), surgical tape (n = 4, 20%), and beauty products (n = 4, 20%). Conclusion: Common allergens associated with lawsuits include latex, surgical tape, and beauty products. Most CD cases adjudicated in the United States since 1983 are associated with toxic exposures.

Prayer-Related Dermatoses in Muslims.

Prayer rituals are an integral part of the daily lives of Muslims worldwide. This comprehensive review aims to explore the common dermatoses associated with prayer among Muslims and provide insights for dermatologists to facilitate accurate diagnosis and reduce unnecessary investigations. A systematic literature search returned 367 published articles, of which 21 met the inclusion criteria. Friction-induced dermatitis was the most frequently reported dermatosis, primarily affecting the forehead, knees, dorsum of the feet, and lateral malleoli. Friction-related marks often present as hyperpigmented lichenified plaques, and are more common in elderly individuals and males. Cases of contact dermatitis and fungal infections were also reported. Allergic contact dermatitis was linked to perfume application before Friday prayers, whereas fungal infections were attributed to increased water retention between toe webs, possibly related to communal ablution and prayer areas. Awareness of these prayer-related dermatoses enables dermatologists to provide holistic care for diverse populations and targeting specific interventions with respect for patients' religious beliefs. For example, Muslim patients with symptomatic frictional dermatoses may benefit from use of padded prayer rugs, especially diabetic patients whose lesions carry an increased risk of progressing to neuropathic ulcers.

Evidence-based management of cutaneous scarring in dermatology part 2: atrophic acne scarring.

Atrophic acne scars are the most common type of acne scars and are classified into three main types: icepick, boxcar, and rolling scars. Various procedures and techniques for atrophic acne scarring are discussed in detail, with stronger evidence-based support for lasers (non-fractional, fractional, ablative, and non-ablative), platelet-rich plasma as adjunctive treatment, chemical peels (glycolic acid, trichloroacetic acid, and Jessner's solution), dermal fillers such as hyaluronic acid, and microneedling, and lesser quality evidence for microdermabrasion, subcision, and lipoaspirate grafting. Further research is needed to optimize treatment protocols, assess the efficacy of monotherapies, and establish standardized guidelines for clinicians. This paper will provide a comprehensive review of the evidence-based management of atrophic acne scars, including currently commonly utilized therapies as well as more innovative treatment options.

Elderberry extract improves molecular markers of endothelial dysfunction linked to atherosclerosis.

Endothelial dysfunction (ED), secondary to diminished nitric oxide (NO) production and oxidative stress, is an early subclinical marker of atherosclerosis. Reduced NO bioavailability enhances the adhesion of monocytes to endothelial cells and promotes atherosclerosis. Elderberry extract (EB) is known to contain high levels of anthocyanins which could exert vascular protective effects. Specifically, we investigated the functional capacity of EB on various markers of ED. Human umbilical vein endothelial cells (HUVEC) were pretreated with EB 50 µg/mL and stimulated with TNF-α 10 ng/mL. Cell viability, apoptosis, oxidative stress; eNOS, Akt, Nrf2, NOX-4, and NF-κB at the protein level were measured. A co-culture model was used to determine whether EB could prevent the adhesion of monocytes (THP-1) to HUVECs. Moreover, the expression of adhesion molecules and pro-inflammatory cytokines were also measured. It was demonstrated that EB prevented TNF-α induced apoptosis and reactive oxygen species production in HUVECs. Additionally, EB upregulated Akt and eNOS activity, and Nrf2 expression in response to TNF-α, whereas it decreased NOX-4 expression and NF-κB activity. EB prevented the adhesion of monocytes to HUVECs, as well as reduced IL-6 and MCP-1 levels, which was associated with inhibition of VCAM-1 expression. Our results demonstrate that EB upregulates key cellular markers of endothelial function and ameliorates markers of ED. EB could be used as a potential nutritional aid for preventing atherosclerosis progression.

Assessment of Cutaneous Vasculitis and Quality of Life.

This survey study assesses the health-related quality of life outcomes in adult patients with cutaneous manifestations of vasculitis.

Systematic review of benefits and practical challenges for application of Mohs surgery for oral tumors.

Mohs micrographic surgery (MMS) may be an effective treatment modality for oral cavity cancers (OCC) due to possibility of more effective visualization of tumor margins and greater preservation of benign tissue. The objective of this study is to review the existing literature on the use of MMS for the treatment of OCC and categorize its uses and limitations. A systematic review was performed in accordance with Assessing the Methodological Quality of Systematic Reviews (AMSTAR) guidelines. PubMed, Scopus, and Google Scholar from inception of databases to January 20, 2023 identified all published studies on the use of MMS for OCC. Nine studies met inclusion criteria. Seventy-seven patients were treated with MMS for OCC, 74 of which (96%) were treated for squamous cell carcinoma (SCC). The tongue was the most common site (n = 57). Six out of seven studies showed no recurrence of disease during the follow-up periods, which ranged from 8 to 42 months, and one study reported significantly lower loco-regional recurrence over a 2-years follow-up period (10.5% vs 25.7%). Mohs technique did not cause a statistically significant increase in operating time. Applicability of MMS is limited by operator comfort with surgical technique and pathological interpretation of specimens in the oral cavity. The main limitation was that various studies did not report specific patient characteristics. In conclusion, MMS may be an effective treatment for OCC, especially for squamous cell carcinomas, and tumors involving the tongue.

Anthocyanins and Vascular Health: A Matter of Metabolites.

Anthocyanins are a subgroup of flavonoid polyphenols previously investigated for improving cardiovascular health and preventing the development of endothelial dysfunction. However, their poor bioavailability raises the question of whether the observed biological activity is due to their metabolites. Phenolic metabolites can reach higher plasma concentrations and can persist in the circulation for periods much longer than their original anthocyanin form; therefore, the biological activity and health promoting effects of anthocyanins may differ from their metabolites. To address this, recent studies have facilitated different cell models, in vivo studies and explored physiologically relevant concentrations to better understand their mechanisms of action. The criteria were chosen based on previous reports demonstrating that anthocyanins can improve endothelial function via modulation of the Akt-endothelial nitric oxide synthase pathway and transcription factors Nrf2 and NF-κB, which made it critical to assess the phenolic metabolites' modes of action via these pathways. This review demonstrates how phenolic metabolites differ in bioactivity from their precursor anthocyanin, demonstrating improved endothelial function in response to inflammatory mediators at concentrations that are tolerated in vivo. The review highlights the crucial need for further studies to focus on improving the bioavailability of metabolites in isolation and explore the effect of metabolites in mixtures.

Allergic Contact Dermatitis Associated With Religious Practices: Review of the Literature.

Allergic contact dermatitis (ACD) may occur secondary to devotional practices in various religions. A systematic review of PubMed was conducted from inception of database to September 9, 2022. Key terms were "contact dermatitis" or "devotional dermatosis" in association with major world religions including "Christianity," "Islam," "Hinduism," "Buddhism," "Sikhism," and "Judaism." Inclusion criteria were determined by presence of a religious practice and associated ACD. Articles referencing other cutaneous reactions such as chemical leukoderma were excluded. In total, 36 of 102 unique articles identified met inclusion criteria. Twenty-two articles referenced Hinduism, 8 referenced Judaism, 5 referenced Islam, 3 referenced Christianity, and 1 article each mentioned Buddhism and Sikhism. Four articles referenced multiple religions. Para-phenylenediamine was the most common contact allergen overall and is found in blackening ingredients mixed with henna for temporary tattoos. Henna tattooing is a cultural practice associated with Hinduism, Islam, and Judaism. Nine unique contact allergens associated with religious practices were identified. Increasing awareness of religious practices that cause ACD will facilitate culturally competent dermatological care.

Acute Myocardial Infarction in a Young Male With COVID-19 Infection.

Coronavirus disease 2019 (COVID-19) infection is a global health crisis resulting in significant morbidity and mortality. The presentation of COVID-19 infection is variable, ranging from an asymptomatic carrier state to multi-organ failure. While cases of COVID-related myocarditis and myocardial dysfunction are well reported, only a few cases of coronary artery thrombosis resulting in myocardial infarction are noted on literature review. However, the previously reported cases were in patients with high risk for coronary artery disease. We hereby report a case of a young man with no significant past medical history or cardiovascular risk factors who presented with severe chest pain and was diagnosed with acute myocardial infarction in the setting of COVID-19 infection requiring intervention. We want to report this case to improve awareness in the community about COVID-related arterial thrombosis and have a high index of suspicion for this regardless of the person's risk factors for cardiovascular diseases.

Evidence-based management of keloids and hypertrophic scars in dermatology.

While normal, controlled wound-healing results in scars that are nearly imperceptible, hypertrophic scars (HTS) and keloids are the result of an abnormal wound-healing process that can leave unsightly, difficult-to-treat lesions. While such scars are classically associated with surgical incisions, they may also result from burns or accidental trauma to the skin. Several different measures can be taken to prevent the formation of scars or treat those that have already formed. Prevention focuses on reducing inflammation during the wound-healing process, and minimizing tension in the lesion when appropriate. Treatments range from non-invasive modalities such as pressure therapy, topicals, and symptom management, to invasive methods such as injections, lasers, and even surgery. While some treatments, such as corticosteroid injections, have been used in the treatment of HTS and keloids for decades, other newer therapies have only been described in case reports or are still in early phases of clinical trials. Because optimal scar management will not be the same for every patient, further investigation of newer agents and methods is warranted and may benefit a great number of patients. This paper will review the evidence-based management of scars, including current widely used treatment options and promising newly emerging therapies.

Analyzing disparities in access to teledermatology compared with dermatology clinic visits before, during, and after COVID-19 quarantine.

The COVID-19 pandemic has caused significant changes in dermatologic care, likely exacerbating health disparities for specific minority populations. The use of teledermatology has also become more prevalent during this period. The aim of this study was to determine if the proportion of teledermatology versus office-based visits varied significantly during three study periods of the COVID-19 pandemic. The secondary objective was to determine whether there are significant differences in the use of office-based dermatology versus teledermatology care across the following demographic subgroups: insurance type, race/ethnicity, age, and language during the same periods. A chart review of dermatology visits in electronic medical records at a tertiary referral center in Washington, DC, was conducted. The overall telehealth visit rate was 0% in the prequarantine period, 61.12% during the quarantine period, and 10.59% in the postquarantine period. After assessing telehealth utilization rates among the demographic subgroups, we noted that Medicaid users, Black patients, 64-year-olds or older, and English speakers may benefit the least from telehealth services. Teledermatology use necessitated by the COVID-19 pandemic may have promoted health care disparities for specific marginalized populations.

Animal model testing for efficacy and adverse effects of bacteriophages against Acinetobacter baumannii.

This study aimed to conduct a detailed study on murine model testing of bacteriophage against Acinetobacter baumannii. These bacteriophages were tested not only for their efficacy in healing wound of murine models infected with multidrug resistant A. baumannii but were also studied for any derangement in hematological parameters as well as liver and kidney function. The study also included any histological changes observed in hepatic and renal tissues of the bacteriophage treated murine animals. This experimental study was conducted at Institute of Basic Medical Sciences, Khyber Medical University, Peshawar and Institute of Pure and Applied Biology, Department of Microbiology and Molecular Genetics, Bahauddin Zakariya University, Multan. A. baumannii isolates were obtained from the Microbiology Department, Armed Forces Institute of Pathology, Rawalpindi. Antimicrobial susceptibility was done by using standard procedures and as per Clinical Laboratory Standards Institute guidelines. Bacteriophages were isolated from sewage water samples collected from different hospitals in Multan. These bacteriophages were characterized and finally used for treating the murine model and efficacy of phage as a therapeutic option was determined by using superficial rat wound model. In this study, the isolated lytic bacteriophage was effective in relatively faster wound healing of the infected animals. Moreover, there were no significant hematological or renal and hepatic profile changes in treated animals. Histology of renal and hepatic tissues was also normal as compared to control animals. Our study concluded that the isolated phage could serve as an attractive therapeutic candidate to combat the deadly multidrug resistant A. baumannii.

Elderberries as a potential supplement to improve vascular function in a SARS-CoV-2 environment.

Coronavirus disease 2019 (COVID-19) pandemic has been triggered by the severe acute respiratory syndrome coronavirus (SARS-CoV-2). Although recent studies demonstrate that SARS-CoV-2 possibly does not directly infect endothelial cells (EC), the endothelium may be affected as a secondary response due to the damage of neighboring cells, circulating pro-inflammatory cytokines, and/or other mechanisms. Long-term COVID-19 symptoms specifically nonrespiratory symptoms are due to the persistence of endothelial dysfunction (ED). Based on the literature, anthocyanins a major subgroup of flavonoid polyphenols found in berries, have been well researched for their vascular protective properties as well as the prevention of cardiovascular disease (CVD)-related deaths. Elderberries have been previously used as a natural remedy for treating influenza, cold, and consequently cardiovascular health due to a high content of cyanidin-3-glucoside (C3G) a major anthocyanin found in the human diet. The literature reported many studies demonstrating that EE has both antiviral and vascular protective properties that should be further investigated as a nutritional component used against the (in)direct effect of SARS-CoV-2 in vascular function. PRACTICAL APPLICATIONS: While previous work among the literature looks promising and builds a suggestion for investigating elderberry extract (EE) against COVID-19, further in vitro and in vivo research is required to fully evaluate EE mechanisms of action and its use as a supplement to aid current therapies.

Antibiograms of Gut Flora of Poultry Farms Workers Reveal Higher Resistance Levels as Compared to Non-Workers.

Introduction: Antibiotics are being used in humans and animals for treatment and control of bacterial infections. Excessive use of antibiotics in the production of poultry is a popular practice, but it poses serious health issues by transferring resistance from farm to humans via food or direct exposure. Study Objective: The objective of this study was to carry out a comparison of the resistance and sensitivity profile of isolated isolates from sewage of toilets that were in use of workers inside the farm and from sewage of household toilets. Methodology: In this study, a total of 320 sewage samples were collected. The antibiotic susceptibility profile was checked by Kirby-Bauer disc diffusion method, and the statistical analysis was carried out by MS excel. Chi-square test was performed to determine whether the antibiograms from two sample types were statistically different from each other or not. Results: From 320 sewage samples, a total of 296 bacterial isolates were isolated among which the leading bacterium was E. coli. The proportion of resistance, ESBL production and MDR was significantly higher in bacteria isolated from sewage of toilets under use of poultry farm workers as compared to the sewage from domestic use toilets. Conclusion: Resistance significantly increased in the bacteria isolated from toilets under use of poultry farm workers as compared to the ones isolated from control sewage samples.

Intensive Poultry Farming Practices Influence Antibiotic Resistance Profiles in Pseudomonas aeruginosa Inhabiting Nearby Soils.

BACKGROUND: The drastic increase in use of antibiotics as a mandatory part of production in poultry and livestock has led to the development of bacterial resistance against antibiotics. The spread of resistant bacteria from poultry to humans increases the risk of treatment failure by antibiotics because of resistance genes transfer. STUDY OBJECTIVE: The objective of the study was to estimate and compare the P. aeruginosa resistance profile collected from areas around the poultry farm premises and areas at least 500 meters away from the nearest poultry farm. We studied the effect of antibiotic usage in farms on the bacterial profile present in the upper layer of soil. METHODOLOGY: A total of 1,200 moist soil samples were collected from areas within a 25 meters range of poultry farms and areas that had no poultry farms in its 500 meters vicinity. P. aeruginosa was cultured and isolated. The antibiotic susceptibility profile was carried out by Kirby-Bauer disc diffusion method and results were analyzed according to CLSI guidelines. Statistical analysis was carried out to check the significance of results. RESULTS: A total of 300 P. aeruginosa isolates were isolated, among which 140 isolates were isolated from areas around the poultry farm premises and had higher prevalence of antibiotic resistance. A total of 160 isolates were isolated from areas outside the poultry farm range. Resistance was not as high as in the isolates from around the farm. The ESBL production was higher in the isolates that were in close contact with the poultry farm as compared to the isolates away from the farm. CONCLUSION: Use of antibiotics in the poultry farm for production significantly increases the resistance in bacterial strains present in the upper layer of soil around the poultry farm within at least a 25 meter range.

Investigations on Acinetophage, QAB 3.4, Targeting Extensively Drug-Resistant Acinetobacter baumannii Isolates.

PURPOSE: Drug resistance against antimicrobials is on the rise at alarmingly high rates. Acinetobacter baumannii is one of the six ESKAPE pathogens which are a significant "one health" issue. Clinical isolates of A. baumannii exhibit MDR phenotype mostly and infrequently the XDR and PDR phenotype. As a result, these infections have one of the highest mortality rates in hospitals. Alternative therapies are urgently needed. METHODS: Various phages were enriched against XDR clinical strain of A. baumannii. A potent phage, QAB 3.4, was further tested against 100 clinical strains. Because of its broad lytic activity, it was further tested for stability, resistance development and as an infection control agent. RESULTS: Phage QAB 3.4 showed broad lytic activity against 100 MDR and XDR clinical isolates representing a wide diversity of infection sites. Assays conducted to document the phage's stability, and ability of clinical isolates to develop resistance against it, showed promising outcomes for its potential use in clinical applications. Phage QAB 3.4 was able to eradicate A. baumannii from pre-inoculated solid surfaces. It provides a proof of concept that phages can be used as environmentally friendly infection control agents. CONCLUSION: We propose the phage QAB 3.4 is a promising candidate for further pre-clinical and clinical studies to test its biosafety and efficacy.

Potential Benefits of Berry Anthocyanins on Vascular Function.

Cardiovascular disease (CVD), such as hypertension and atherosclerosis, is the leading cause of global death. Endothelial dysfunction (ED) is a strong predictor for most CVD making it a therapeutic target for both drug and nutrition interventions. It has been previously shown that polyphenols from wine and grape extracts possess vasodilator activities, due to the increased expression and phosphorylation of the endothelial nitric oxide synthase (eNOS), and consequent vasodilator nitric oxide (NO) production. This is vital in the prevention of ED, as NO production contributes to the maintenance of endothelial homeostasis. Moreover, polyphenols have the ability to inhibit reactive oxygen species (ROS), which can cause oxidative stress, as well as suppress the upregulation of inflammatory markers within the endothelium. However, while the majority of the research has focused on red wine, this has overshadowed the potential of other nutritional components for targeting ED, such as the use of berries. Berries are high in anthocyanin flavonoids a subtype of polyphenols with studies suggesting improved vascular function as a result of inducing NO production and reducing oxidative stress and inflammation. This review focuses on the protective effects of berries within the vasculature.
