Patients experiencing homelessness (PEH) suffer from a high burden of cutaneous fungal infections. Preventative treatment is important as such infections can lead to harmful complications such as cellulitis and even osteomyelitis. There are sparse data regarding cutaneous fungal infections of homeless populations and management in low-resource settings. A MEDLINE search was conducted using the key terms "cutaneous," "fungal," "infections," "dermatophytes," and "homeless." The search included casecontrol, cohort, and randomized controlled trials published in the English language. This scoping review of studies yielded information with regard to practical treatment advice for providers in low-resource settings, including medical, hygiene, prevention, and treatment options for PEH with cutaneous fungal infections, the most common of which were tinea pedis (3-38%) and onychomycosis (1.6-15.5%). Few studies have been conducted on the differences between sheltered and unsheltered homeless patients, which can have treatment implications. Systemic antifungal therapy should be carefully considered for diffuse, refractory, or nail-based cutaneous fungal infections if there is a history of alcohol use disorder or liver disease. While PEH have a high risk of alcohol use disorder, this can make definitive treatment challenging.

Pornography addiction is an area of increasing concern, particularly due to the ubiquitous nature of pornographic material on the Internet. Even so, there is no formal Diagnostic and Statistical Manual of Mental Disorders (DSM-5) inclusion of compulsive pornography use as a behavioral addiction. Although the psychosocial impacts of pornography addiction have been studied, the risk of direct skin injuries and behavioral changes brought about by excessive pornography usage remain to be seen. Adult males constitute the majority of cases of engaging in risky and violent sexual behaviors with an unclear association with pornography consumption. Adult females may be likely to copy pubic hair trimming patterns analogous to those seen in pornographic content, even though attitudes towards labiaplasty are unclear. Finally, adolescents regularly exposed to pornography have been found to replicate sexual activity seen in pornographic material and have earlier sexual activity. In the literature evaluated, an association between pornographic material and direct cutaneous disease remains a major area of further research.

BACKGROUND People experiencing unsheltered homelessness (PEUH) are a vulnerable patient cohort who suffer from high levels of disease morbidity and mortality [1]. Because this population experiences complicated and frequent barriers to care, these patients are often unable to receive timely and specialized care. Research Electronic Data Capture (REDCap) is a modular web application that can be used to create databases for clinical research and projects [4]. OBJECTIVE This cross-sectional study evaluates the use of a custom, REDCap-based electronic medical record in cutaneous disease management for a Miami-based Street Medicine organization. METHODS Between July 2021 - January 2022, REDCap records were retrieved pertaining to skin or nail-based problems among PEUH. In cases that required further elaboration, additional fields were added into patient charts such as wound care (Figure 2a). RESULTS Among 140 unique patients seen in a street setting, 112 diagnoses were recorded. The sample evaluated included 68.1% males and 31.9% females. The patient cohort was diverse, with 50.2% black, 45.8% white, and the remainder asian or native american. The highest morbidity lesions in terms of disability and risk for infection encountered were chronic wounds and ulcers, many of which required multiple care instances. CONCLUSIONS The use of a free, customizable REDCap system was instrumental in recording cutaneous diseases among PEUH, both for treatment and follow-up purposes. REDCap can be a promising tool for charitable organizations with limited funding by virtue of its cost-effective and accessible management of sensitive patient data. REDCap-based electronic medical records appear to be valuable adjuncts to established Street Medicine teams, particularly for the use of specialized services like dermatology. These can be modified for special circumstances and patient populations, thereby improving the delivery of care to people experiencing unsheltered homelessness in a cost-effective manner.

Skin cancers are concerning for unsheltered people experiencing homelessness because of their high levels of sun exposure. Currently, there is little data on the prevalence of skin cancers in people experiencing homelessness. Skin diseases are often untreated in people experiencing homelessness due to a lack of access to specialized care. Miami Street Medicine (MSM) is an organization that provides people experiencing homelessness in the Miami Health District with medical care in a nonclinical street setting, near overpasses, sidewalks, and encampments. We present a case of an unsheltered 59-year-old male with a pigmented, 2 cm × 2 cm facial lesion that developed over several years. Through a teledermatology consultation, his lesion was highly suspicious of melanoma and further evaluation was recommended. Due to a lack of insurance, he could not be treated at any dermatology clinic. Coincidentally, 2 weeks later, he developed cellulitis of his lower extremity and was admitted to the local safety-net hospital through the emergency department. By coordinating with his primary inpatient team, MSM was able to include a biopsy of the lesion as part of his hospital stay. The results demonstrated melanoma in situ. The vital course of action was to ensure treatment before metastasis. After registration for insurance and follow-up with a surgical oncology team, he is weeks away from excision and reconstruction surgery. His unsheltered status made follow-up difficult, but MSM bridged the gap from the street to the clinical setting by incorporating teledermatology into patient evaluations and leveraging connections with community shareholders such as charitable clinics and volunteer physicians. This case also represents the barriers to care for cancer-based dermatologic outreach among people experiencing homelessness.

Pemphigus vulgaris (PV) is a rare disease that affects the skin and mucous membranes, causing blistering and erosions. Identifying and effectively managing atypical presentations of pemphigus vulgaris can be challenging due to its rarity. We describe a 32-year-old male patient with a medical history including prediabetes, moderate asthma, hyperlipidemia, coccidioidomycosis, and respiratory infections. He was evaluated via telehealth in the allergy and immunology clinic for uncontrolled asthma. Initially, he complained of a whitish film in the mouth while on treatment with fluticasone and salmeterol. He also noted new vesicular lesions on his scalp and body. When evaluated later in the clinic, he was found to have oral and periungual erosions as well as paronychia. After promptly referring to dermatology, histopathological examination and direct immunofluorescence testing were performed on the patient's lesions, revealing changes consistent with PV. Treatment with prednisone and rituximab resulted in the complete resolution of the patient's bullae and nail deformities over several months. This case highlights the importance of a thorough evaluation of complex medical histories and diagnostic testing in managing asthma and allergy symptoms. It also emphasizes the need for a multidisciplinary approach involving specialists such as immunologists, dermatologists, and infectious disease experts in the diagnosis and management of complex cases.
