Natural Treatment Options for Nail Disorders.

The growing demand for natural treatments has raised concerns among clinicians due to limited scientific evidence supporting their use. This review article addresses the issue by assisting dermatologists and general practitioners in recommending natural treatments for the following common nail disorders: nail brittleness, onychomycosis, periungual verrucae, paronychia, chloronychia, nail psoriasis, nail lichen planus, onychocryptosis, onycholysis, and congenital malalignment of the great toenail. One limitation is the scarcity of existing reviews on natural treatment options for nail disorders in the literature. Through a comprehensive review of existing literature, this article consolidates the available evidence on natural treatment options for these conditions. Although some natural treatments for nail disorders are supported by scientific evidence, the indiscriminate use of such remedies may lead to severe poisoning and health problems. Given the widespread and increasing use of natural treatments, clinicians play a pivotal role in educating patients about evidence-based remedies and debunking misleading claims. By doing so, clinicians can enhance patient safety and improve treatment outcomes. It is essential for healthcare professionals to be well-informed and equipped with the knowledge to differentiate between effective natural treatments and unverified claims, ensuring that patients receive appropriate care.

Cutaneous Fungal Infections in Patients Experiencing Homelessness and Treatment in Low-Resource Settings: A Scoping Review.

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 case-control, 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.

The prevalence of nonmelanoma skin cancer in a population of patients with oculocutaneous albinism in Haiti.

BACKGROUND: Multiple studies have examined the prevalence of nonmelanoma skin cancers (NMSC) in patients with oculocutaneous albinism (OCA). However, to date, no studies have examined this data in Caribbean populations. METHODS: This study is a cross-sectional study of 106 patients with OCA who were seen at the Oculocutaneous Albinism Clinic in Port-au-Prince and Gros Morne, Haiti, between the dates of February 2017 and June 2018. RESULTS: In our population, 31/106 (29%) patients were found to have NMSC, 10/31 (32%) had BCC, 12/31 (39%) had SCC, and 9/31 (29%) had both types of NMSC. The most common age groups were 31-40 years, with the overall range of ages being 18-63 years. Also, 60/106 (57%) of the patients had actinic keratoses (AK). CONCLUSIONS: Our study provides new data examining the prevalence of NMSC within a population of patients with OCA in Haiti. Overall, it shows that patients with albinism develop NMSC at an earlier age compared with the rest of the population. Therefore, appropriate skin cancer screening and surveillance should be implemented within this high-risk population group.

Monodactylous Longitudinal Melanonychia: A Sign of Bowen's Disease in Skin of Color.

INTRODUCTION: Monodactylous longitudinal melanonychia (LM) may represent both benign and malignant dermatologic disorders. However, squamous cell carcinoma in situ (SCCis) is not commonly considered in this setting. CASE PRESENTATION: In this report, we present 2 cases of SCCis of the nail matrix in patients with skin of color who presented with monodactylous LM involving the lateral aspect of the nail. CONCLUSION: These cases suggest that SCCis should be included in the differential diagnosis for monodactylous LM, especially when involving the lateral nail plate in darker skin.

Treatment of Chemotherapy-Induced Subungual Pyogenic Granuloma with Topical Timolol Solution.

INTRODUCTION: Subungual pyogenic granuloma (PG) can be caused by numerous medications including chemotherapeutic agents. These lesions grow rapidly, oftentimes causing significant pain and bleeding, prompting patients to seek treatment. The management of subungual PG ranges from topical steroids to surgical excision. However, patients with chemotherapy-induced PGs are prone to developing multiple or recurrent lesions. Therefore, finding a therapeutic option that effectively eliminates the tumor and prevents the need for repeated procedural interventions is important. The use of topical ß-adrenergic antagonists has been reported to be effective in regressing cutaneous PG. CASE PRESENTATION: In this report, we present a case of chemotherapy-induced subungual PG of the toenail arising in a 62-year-old woman that was successfully treated with topical timolol solution. CONCLUSION: This case highlights the promising use of timolol solution for therapeutically challenging PGs, such as those of subungual regions. This option may be particularly useful for individuals who are vulnerable to multiple PGs secondary to chemotherapy who wish to avoid repeated procedural interventions.

The Impact of COVID-19 on the Faces of Frontline Healthcare Workers.

As the coronavirus epidemic continues, a host of new cutaneous complications is seen on the faces of frontline healthcare workers wearing personal protective equipment on a daily basis. To minimize the risk of COVID-19 infection, healthcare workers wear tight-fitting masks that lead to an excessive amount of pressure on the facial skin. Mechanical pressure, mask materials, and perspiration can all lead to various types of cutaneous lesions such as indentations of the face, skin tears, post-inflammatory hyperpigmentation, ulceration, crusting, erythema, and infection. The objective of this article is to provide effective and straightforward recommendations to those health care providers using facial masks in order to prevent skin-related complications.

Prevalence of Skin Disease in Urban Haiti: A Cross-Sectional Study.

The prevalence of skin disease varies with geographic location and may be affected by cultural factors. In Haiti, the combination of poor health care access, infrastructure lack, and natural disasters may affect the prevalence of skin conditions. Unfortunately, little epidemiological information has been obtained on the prevalence of skin diseases in Haiti. The objective of this study is to describe data on the prevalence of dermatological conditions in urban areas of Haiti. Univariate, bivariate, and χ2 analyses were used to evaluate associations. During February 2016, we documented 137 patients. The mean age was 27.7 years; most of the subjects were women (61.3%) in a cohort mostly adult (67.1%). The infectious and inflammatory dermatoses were the most prevalent (74.2%). Infectious skin diseases were more prevalent in men and in adults in general (p < 0.01). Inflammatory conditions were also more common in adults (p < 0.05). Additionally, alopecia and dyschromia were limited to women (p < 0.01). Infectious skin diseases, in particular fungal infections, were amongst the most common diagnoses in the urban area of Haiti. Therefore, improved access to antimicrobial and anti-inflammatory medications would likely benefit Haitian patients with dermatological conditions. These findings may help local public health officials and future dermatological expeditions better serve this population.

Worn down nails after acrylic nail removal.

Worn-down nail syndrome is a nail disorder characterized by thinning of the distal nail plate caused by repetitive chemical or mechanical trauma. We present a previously undescribed source of worn-down nail syndrome caused by trauma from nail filing after acrylic nail removal.

Disulfiram induces copper-dependent stimulation of reactive oxygen species and activation of the extrinsic apoptotic pathway in melanoma.

Melanoma is the most aggressive and deadly form of skin cancer. The current standard of care produces response rates of less than 20%, underscoring the critical need for identification of new effective, nontoxic therapies. Disulfiram (DSF) was identified using a drug screen as one of the several compounds that preferentially decreased proliferation in multiple melanoma subtypes compared with benign melanocytes. DSF, a member of the dithiocarbamate family, is a copper (Cu) chelator, and Cu has been shown previously to enhance DSF-mediated growth inhibition and apoptosis in cancer cells. Here, we report that in the presence of free Cu, DSF inhibits cellular proliferation and induces apoptosis in a panel of cell lines representing primary and metastatic nodular and superficial spreading melanoma. Both decreased cellular proliferation and increased apoptosis were seen at 50-500 nmol/l DSF concentrations that are achievable through oral dosing of the medication. In the presence of Cu, DSF caused activation of the extrinsic pathway of apoptosis as measured by caspase-8 cleavage. The addition of Z-IETD-FMK, a selective caspase-8 inhibitor, was protective against DSF-Cu-induced apoptosis. Production of reactive oxygen species (ROS) in response to DSF-Cu treatment preceded the induction of apoptosis. Both ROS production and apoptosis were prevented by coincubation of N-acetyl cysteine, a free radical scavenger. Our study shows that DSF might be used to target both nodular and superficial spreading melanoma through ROS production and activation of the extrinsic pathway of apoptosis.
