All patients were satisfied of the clinical result and reported a complete reduction in hair loss. No serious adverse side effects were reported.
The use of growth factors associated with iontophoresis technique is a useful treatment for treating and preventing androgenetic alopecia. In addition, in case of associated telogen effluvium, this technique allows for an early stop of hair shedding, especially when cosmetic procedures do not provide satisfactory results in patients.

The preoperative prediction of whether melanomas are invasive or in situ can influence initial management.
This study evaluated the accuracy rate, interobserver concordance, sensitivity and specificity in determining if a melanoma is invasive or in situ, as well as the ability to predict invasive melanoma thickness based on clinical and dermoscopic images.
In this retrospective, single-center investigation, 7 dermatologists independently reviewed clinical and dermoscopic images of melanomas to predict if they were invasive or in situ and, if invasive, their Breslow thickness. Fleiss' and Cohen's kappa (κ) were used for interobserver concordance and agreement with histopathological diagnosis.
We included 184 melanomas (110 invasive and 74 in situ). Diagnostic accuracy ranged from 67.4% to 76.1%. Accuracy rates for in situ and invasive melanomas were 57.5% (95% confidence interval [CI], 53.1%-61.8%) and 81.7% (95% CI, 78.8%-84.4%), respectively. Interobserver concordance was moderate (κ = 0.47; 95% CI, rmoscopy of suspected melanomas is recommended for choosing appropriate surgical margins.Pagetoid spread of melanocytes in the epidermis is a common indicator of melanocytic atypia, both histopathologically and with reflectance confocal microscopy (RCM). Specifically on RCM, large, bright, atypical dendritic and/or roundish cells are characteristic of melanoma. However, intraepidermal Langerhans cells (ILC) create the potential for diagnostic ambiguity on RCM. We describe one case of a pigmented facial lesion that was initially diagnosed as lentigo maligna (LM) due to numerous atypical perifollicular dendritic cells on RCM. Additionally, we present the findings of a literature review for similar reported cases conducted by searching the following terms on PubMed reflectance confocal microscopy, RCM, lentigo maligna, melanoma, Langerhans cells, dendritic cells, and atypical cells. SR59230A supplier In our case, the lesion was determined to be a solar lentigo on histopathology. Immunohistochemistry (IHC) with CD1a identified the atypical-appearing cells as ILC, as it did in 54 reported cases of benign lesions (benign melanocytic nevus, Sutton/halo nevus, labial melanotic macule, and solar lentigo) misdiagnosed as malignant on RCM (melanoma, lip melanoma, lentigo maligna, and LM melanoma). According to our case and the literature, both ILC and atypical melanocytes can present with atypical-appearing dendritic and/or roundish cells under RCM. Currently, there is no method to distinguish the two without IHC. Therefore, the presence of pagetoid cells should continue to alert the confocalist of a potential neoplastic process, prompting biopsy, histopathologic diagnosis, and IHC differentiation.
Skin cancer has become one of the world's leading health problems, and incidence rates are on the rise. The leading causes of skin cancer are sun exposure, family history and sunburn, and the most agreed-upon preventative behaviors are sunscreen application and sun avoidance.
This study assessed the knowledge of the causes of skin cancer and awareness of preventative measures in Saudi Arabia.
A cross-sectional study was conducted among 529 participants in a WhatsApp group over 3 months. Consenting participants completed a validated, 18-item questionnaire.
Of 529 total participants, nearly 55% of participants reported an awareness of skin cancer, 35% understood its metastasis and 55.1% knew about its spread. However, 44% of participants were unaware of the different types of the disease. Social media was reported to be the most common source of information. The majority of participants were able to identify symptoms of skin cancer and had knowledge of risk factors. Most participants understood proper preventative measures, and reported that they use sunscreen regularly.
The general knowledge of skin cancer in Saudi Arabia is not high but is increasing. However, sun-protective behaviors are lacking, despite the population's knowledge of the benefits. Awareness campaigns and incentive programs may encourage better preventative behavior. Future studies should explore participants' awareness of more specific aspects of skin cancer using a more diverse and extensive population sample.

Dietary supplements are popular among US consumers and claim to address a variety of conditions, including acne. Acne supplements containing vitamin A are of particular interest, due to the potentially teratogenic effects of vitamin A doses over 10,000 IU.
This study examined dosage, pregnancy risks, and labeling of vitamin A-containing acne supplements available online.
An Internet search of acne supplements sold online was conducted between March and May 2020. Supplement labels and websites were analyzed for vitamin A content and pregnancy warnings, and then divided into categories based on dosage and teratogenic risk.
A total of 49 acne supplements was found, and of these 26 (53%) contain vitamin A. Three supplements are likely teratogenic, 4 contain vitamin A doses exceeding the daily level of intake that meets the nutritional needs of most people, and 15 have an unknown teratogenic risk. Among the 6 supplements with over 10,000 IU vitamin A, 2 have no pregnancy warning at all, including the supplement with the highest vitamin A dose found in this study.
