Dermatologic concerns are discussed in about a third of all primary care visits. This review discusses treatments for common dermatologic diagnoses addressed in primary care settings, with an emphasis on new and emerging treatments. Topical, oral, and injectable treatment of common forms of alopecia, facial rashes, atopic dermatitis, psoriasis, seborrheic dermatitis, and stasis dermatitis will be discussed to help increase comfort in prescribing and alert providers to common side effects or complications of more intensive treatments used by dermatologists.

Sudden transient loss of vision after an acute bout of alcohol consumption in patients with chronic alcoholism is rare. The underlying mechanism is a transient depression of the endothelial pump due to ethanol toxicity following a large amount of alcohol consumption in chronic alcoholic patients. Here, we report a rare case of a 60-year-old male patient who came to the outpatient department with complaints of sudden loss of vision associated with redness following a large amount of alcohol consumption. The case was managed by prompt diagnosis and topical and oral corticosteroid therapy. This is a rare case of acute toxic endotheliitis due to ethanol toxicity with only a few cases reported in the past.

BACKGROUND: Evidence supporting topical steroids for the treatment of chronic rhinosinusitis without nasal polyposis (CRSsNP) is unclear. Recent trials describe alternative topical steroid delivery modalities, including rinses and exhalation delivery system (EDS), necessitating a re-examination of the current literature.
METHODS: Cochrane Library, CINAHL, PubMed, and Scopus databases were searched from inception to February 13, 2024 for placebo-controlled randomized control trials on topical steroids used to treat CRSsNP, including topical spray, nasal irrigation, sinonasal catheter, and EDS modalities. Primary outcome measures included total symptom scores (TSS) (Δ) and response rates (odds ratio).
RESULTS: Ten trials (N = 751) were included for meta-analysis, with a mean age of 47.5 years (range: 18-80 years; 95% confidence interval [CI]: 43.9-51.2 years). Topical steroids delivered by any method significantly improved TSS in CRSsNP patients (Δ0.4; 95% CI: 0.3-0.6; p < 0.0001). When stratified by allergy status, CRSsNP patients without allergy had significantly improved TSS when treated with EDS (Δ0.4; 95% CI: 0.1-0.7; p = 0.01), but not with topical spray (Δ0.04; 95% CI: -0.9 to 1.0; p = 0.94). Patients treated with EDS or sinonasal catheter responded significantly better compared to placebo (odds ratio [OR]: 3.4; 95% CI: 1.9-6.0; p < 0.0001; OR: 12.4; 95% CI: 1.8-83.8; p < 0.01), whereas patients treated with topical spray had no significant difference (OR: 1.8; 95% CI: 0.9-4.0; p = 0.12).
CONCLUSIONS: Topical steroids are effective in treating CRSsNP, especially when delivered via EDS or sinonasal catheter. Future trials comparing steroid delivery mechanisms using validated outcome measures in CRSsNP populations are needed.

Background and objective In corneal neovascularization, the peri-corneal vascular structure grows into a normally avascular cornea. This is due to an imbalance between the angiogenic and anti-angiogenic factors that sustain corneal transparency. There are various etiologies of this condition, and they can be divided into infective or non-infective causes, such as inflammation, trauma, or surgical causes. Corneal neovascularization has been shown to improve with the current treatments using steroids and anti-vascular endothelial growth factors. This study aimed to evaluate the effectiveness of topical bevacizumab as an anti-angiogenic agent in patients with corneal neovascularization. Methods This retrospective study included patients who suffered corneal neovascularization of various etiologies and completed six months of topical bevacizumab therapy between 2020 and 2022 at the Universiti Kebangsaan Malaysia Medical Centre. Results A total of 16 patients received treatment with topical bevacizumab over the three-year study period. Based on specified inclusion and exclusion criteria, 12 patients were eligible for inclusion in this study. Eight patients (66%) showed improvement in terms of either \'clock hours\' of improvement, morphology, or regression of corneal neovascularization. All infective causes of corneal neovascularization showed improvement on completion of bevacizumab compared to other causes. Conclusion Topical bevacizumab can be one of the treatment choices for corneal neovascularization. As the outcome varies depending on the severity and chronicity of the condition, the attending ophthalmologist should treat each case differently. Although topical bevacizumab is more effective in mild and moderate cases, the indications for its use in chronic cases remain debatable as the results are unfavorable in such cases.

Sarcoidosis is a systemic disease that affects the skin in about 25% of patients. The treatment of cutaneous sarcoidosis is guided by the extent of lesions, associated symptoms and organ involvement. To evaluate rates of response to various potential first-line treatments for cutaneous sarcoidosis during the year following treatment initiation. This retrospective multicentre study included 120 patients with cutaneous sarcoidosis. Treatment response was assessed retrospectively from the patients\' medical records. Univariate logistic regression analysis, with an estimation of unadjusted odds ratios (OR) and their 95% CI ,was performed to identify factors associated with complete cutaneous remission (CR), followed by multivariate logistic regression analysis. At one year, 43 of the 120 (36%) included patients had CR. The best response rates were obtained with oral corticosteroids (12/21, 57%), followed by a combination of hydroxychloroquine and topical steroids (6/13, 46%). In multivariate analysis, lupus pernio was the only predictor of a poor cutaneous response. We suggest the use of a combination of hydroxychloroquine and topical steroids as an optimal first-line treatment for cutaneous sarcoidosis, given the known adverse effects of systemic corticosteroids.

The fact that genetic and environmental factors could trigger disruption of the epithelial barrier and subsequently initiate a TH2 inflammatory cascade conversely proposes that protecting the same barrier and promoting adequate interactions with other organs, such as the gut, may be crucial for lowering the risk and preventing atopic diseases, particularly, food allergies. In this review, we provide an overview of structural characteristics that support the epithelial barrier hypothesis in patients with atopic dermatitis, including the most relevant filaggrin gene mutations, the recent discovery of the role of the transient receptor potential vanilloid 1, and the role involvement of the microbiome in healthy and damaged skin. We present experimental and human studies that support the mechanisms of allergen penetration, particularly the dual allergen exposure and the outside-in, inside-out, and outside-inside-outside hypotheses. We discuss classic skin-targeted therapies for food allergy prevention, including moisturizers, steroids, and topical calcineurin inhibitors, along with pioneering trials proposed to change their current use (Prevention of Allergy via Cutaneous Intervention and Stopping Eczema and ALlergy). We provide an overview of the novel therapies that enhance the skin barrier, such as probiotics and prebiotics topical application, read-through drugs, direct and indirect FLG replacement, and interleukin and janus kinases inhibitors. Last, we discuss the newer strategies for preventing and treating food allergies in the form of epicutaneous immunotherapy and the experimental use of single-dose of adeno-associated virus vector gene immunotherapy.

Lichen sclerosus (LS) and lichen planus (LP) are chronic inflammatory dermatoses of unknown aetiology. They pose the most important differential diagnoses of inflammatory dermatoses in the genital area. There is often a delay in diagnosing LS and LP and subsequently treatment is initiated late in the course of the disease, which will lead to scarring and a decreased quality of life. There is an increased risk of the development of malignancies in the genital area in both diseases; however, early and continuous treatment with potent topical steroids will decrease this risk.
UNASSIGNED: Der Lichen sclerosus (LS) und Lichen planus (LP) sind chronische, entzündliche Hauterkrankungen unklarer Ätiologie. Sie sind die wichtigsten „gegenseitigen“ Differenzialdiagnosen entzündlicher Hauterkrankungen im Genitalbereich. Der LS und LP werden oft zu spät diagnostiziert und entsprechend zu spät behandelt, dies kann zu Vernarbungen mit schwerwiegenden Einschränkungen der Lebensqualität führen. Bei beiden Dermatosen besteht ein erhöhtes Risiko, Malignitäten im anogenitalen Bereich zu entwickeln, eine frühe und konsequente Behandlung mit potenten lokalen Kortisonexterna verringert dieses Risiko.
