The growing demand for natural and sustainable skincare products has driven interest in plant-based active ingredients, especially from in vitro cultures. This placebo-controlled study investigated the impact of a facial cream containing 2% Kickxia elatine (L.) Dumort cell suspension culture extract on various skin biophysical parameters. The cream was applied to the cheek once daily for six weeks on 40 healthy female volunteers between the ages of 40 to 49. The evaluated skin parameters including skin hydration, transepidermal water loss (TEWL), erythema intensity (EI), melanin intensity (MI), skin surface pH, and skin structure, wrinkle depth, vascular lesions, and vascular discolouration. The results indicated that significant improvements were observed in skin hydration (from 40.36 to 63.00 AU, p < 0.001) and there was a decrease in TEWL score (14.82 to 11.76 g/h/m², p < 0.001), while the skin surface pH was maintained (14.82 to 11.76 g/h/m², p < 0.001). Moreover, the K. elatine cell extract significantly improved skin structure values (9.23 to 8.50, p = 0.028), reduced vascular lesions (2.72 to 1.54 mm², p = 0.011), and lowered skin discolouration (20.98% to 14.84%, p < 0.001), indicating its moisturising, protective, brightening, and soothing properties. These findings support the potential use of K. elatine cell extract in dermocosmetic formulations targeting dry, sensitive, or ageing skin. Full article

Background and clinical significance: Trichoblastomas are rare, mixed epithelial tumors with a mesenchymal component and hair follicle differentiation. Case presentation: Herein, we present a case report of a 51-year-old female patient presenting to the obstetrics and gynecology department with complaints of edema and erythema of the right Bartholin gland, and a lesion measuring 2 cm on the right lateral edge of the mons pubis, towards the inguinal fold. Marsupialization of the Bartholin gland was performed, as well as an incision into the pubo-inguinal lesion, which the patient depicted as grossly resembling an ingrown hair. Upon incision into the pubic–inguinal lesion, it was dark brown in color and spontaneously popped out of the subcutis, without an attempt at enucleation. Histology and subsequent immunohistochemistry of the lesion showed a blue basaloid tumor with an extensive pigment component located deep in the dermis that was sharply demarcated from the surrounding tissues. Conclusion: Immunohistochemistry was diffusely and strongly positive for epithelial markers; melanocytic markers were positive only in dendritic melanocytes dispersed within the tumors, and the proliferative index was low. As such, the tumor was identified as melanotrichoblastoma. Full article

Chronic atrophic gastritis and intestinal metaplasia (IM) are gastric precancerous conditions (GPCs) associated with an increased risk of gastric cancer. Early detection and accurate characterization of GPC are therefore crucial for risk stratification and the implementation of preventive strategies. In the absence of clear mucosal changes observed through white-light imaging (WLI) or virtual chromoendoscopy, endocytoscopy can help unveil the presence of GPC by enabling in vivo assessment of nuclear and cellular structures at ultra-high magnification. Endocytoscopy is typically performed using WLI following dye-based staining of the mucosa. In this case, we demonstrate that combining endocytoscopy with the texture and color enhancement imaging (TXI) mode substantially improves the assessment of the gastric mucosa. In a 61-year-old man undergoing esophagogastroduodenoscopy, WLI showed multifocal erythema in the stomach, without clearly visible lesions on either WLI or narrow-band imaging. Conventional endocytoscopy revealed multiple small spots of IM with characteristic changes in glandular structures, which were even more evident when using the TXI mode. Histological analysis of targeted biopsies confirmed small foci of IM in both the antrum and corpus. The patient was enrolled in a surveillance program because of his clinical background. The combination of endocytoscopy with the TXI mode significantly enhances the delineation of mucosal and cellular architecture, supporting a more accurate optical diagnosis. Full article

Mammary Paget disease (MPD) is a rare cutaneous malignancy associated with underlying ductal carcinoma in situ (DCIS) or invasive ductal carcinoma (IDC). Clinically, it appears as eczematous changes in the nipple and areola complex (NAC), which may include itching, redness, crusting, and ulceration; these symptoms can sometimes mimic benign dermatologic conditions such as nipple eczema, making early diagnosis challenging. A 56-year-old woman presented with persistent erythema and scaling of the left nipple, which did not respond to conventional dermatologic treatments: a high degree of suspicion prompted further investigation. Reflectance confocal microscopy (RCM) revealed atypical, enlarged epidermal cells with irregular boundaries, while line-field confocal–optical coherence tomography (LC-OCT) demonstrated thickening of the epidermis, hypo-reflective vacuous spaces and abnormally large round cells (Paget cells). These non-invasive imaging findings were consistent with an aggressive case of Paget disease despite the absence of clear mammographic evidence of underlying carcinoma: in fact, several biopsies were needed, and at the end, massive surgery was necessary. Non-invasive imaging techniques, such as dermoscopy, RCM, and LC-OCT, offer a valuable diagnostic tool in detecting Paget disease, especially in early stages and atypical forms. Full article

Human granulocytic anaplasmosis is an emerging tick-borne disease. Although Anaplasma phagocytophilum has been identified in vectors and animal reservoirs in Romania, evidence of human exposure has not yet been reported. This study aimed to generate initial evidence of human infection by evaluating A. phagocytophilum antibodies in individuals with recent tick exposure. We conducted a cross-sectional serosurvey between 2023 and 2024 at a tertiary care hospital in Bucharest, enrolling 80 participants 4 to 12 weeks following a tick bite. Serum IgG antibodies against A. phagocytophilum were detected using an indirect immunofluorescence assay, with a titer of ≥1:64 considered indicative of seropositivity. Eight (10%) participants tested positive for A. phagocytophilum IgG antibodies. Seropositivity was not significantly associated with demographics, geographical region, or clinical symptoms. However, fatigue and myalgia were more frequently seen in A. phagocytophilum IgG seropositive individuals. Notably, 43.8% of all participants reported erythema migrans, including five of the eight individuals with positive A. phagocytophilum IgG serology. This study provides the first serological evidence of human exposure to A. phagocytophilum in Romania. A 10% seroprevalence in this high-risk group suggests that anaplasmosis may be underrecognized. Clinicians should consider it in patients with tick exposure and compatible symptoms. Full article

Background/Objectives: “Ozempic face” is an aesthetic side effect associated with the use of the antidiabetic agent Ozempic (semaglutide), characterized by a prematurely aged and fatigued facial appearance due to rapid weight loss. Currently, treatment options for this condition are limited. In this study, we present our clinical experience with the BodyTite device, provided by InMode Italy S.r.l. (Rome, Italy). Materials and Methods: We report a case series involving 24 patients (19 women and 5 men, aged 27–65 years), treated with subdermal bipolar radiofrequency (Endotissutal Bipolar Radiofrequency) between 2023 and 2024. All patients underwent a minimum follow-up of 12 months. At the end of the follow-up period, patients rated their satisfaction on a from 0 to 10 scale, and an independent expert assessed the stability of clinical outcomes. Results: The majority of patients reported high satisfaction levels (≥8), which correlated with the independent expert’s evaluation of treatment efficacy and result stability. The only observed adverse event was transient cutaneous erythema. Conclusions: “Ozempic face” is an increasingly common side effect associated with newer classes of antidiabetic medications. Although these drugs offer significant metabolic benefits, the accompanying facial volume loss and aging are often poorly tolerated by patients. Our findings suggest that subdermal bipolar radiofrequency represents a safe, low-risk, and cost-effective therapeutic option for the aesthetic management of Ozempic face. Full article

Background: Wound healing and scar management remain significant challenges in dermatology and aesthetic medicine. Recent advances in regenerative medicine have introduced plant-derived exosome-like nanoparticles (PDENs) as potential therapeutic agents due to their bioactive properties. This study examines the clinical application of rose stem cell exosomes (RSCEs) in combination with established treatments for managing different types of scars. Methods: A case series of four patients with different scar etiologies (dog bite, hot oil burn, forehead trauma, and facial laser treatment complications) was treated with RSCEs in combination with microneedling (Dermapen 4.0, 0.2–0.4 mm depth) and/or thulium laser therapy (Lutronic Ultra MD, 8–14 J), or as a standalone topical treatment. All cases underwent sequential treatments over periods ranging from two to four months, with comprehensive photographic documentation of the progression. The efficacy was assessed through clinical photography and objective evaluation using the modified Vancouver Scar Scale (mVSS) and the Patient and Observer Scar Assessment Scale (POSAS), along with assessment of scar appearance, texture, and coloration. Results: All cases demonstrated progressive improvement throughout the treatment course. The dog bite scar showed significant objective improvement, with a 71% reduction in modified Vancouver Scar Scale score (from 7/13 to 2/13) and a 61% improvement in Patient and Observer Scar Assessment Scale scores after four combined treatments. The forehead trauma case exhibited similar outcomes, with a 71% improvement in mVSS score and 55–57% improvement in POSAS scores. The hot oil burn case displayed the most dramatic improvement, with a 78% reduction in mVSS score and over 70% improvement in POSAS scores, resulting in near-complete resolution without visible scarring. The facial laser complication case showed a 75% reduction in mVSS score and ~70% improvement in POSAS scores using only topical exosome application without device-based treatments. Clinical improvements across all cases included reduction in elevation, improved texture, decreased erythema, and better integration with surrounding skin. No adverse effects were reported in any of the cases. Conclusions: This preliminary case series suggests that plant-derived exosome-like nanoparticles, specifically rose stem cell exosomes (RSCEs), may enhance scar treatment outcomes when combined with microneedling and laser therapy, or even as a standalone topical treatment. The documented objective improvements, measured by standardized scar assessment scales, along with clinical enhancements in scar appearance, texture, and coloration across different scar etiologies—dog bite, burn, traumatic injury, and iatrogenic laser damage—suggest that this approach may offer a valuable addition to the current armamentarium of scar management strategies. Notably, the successful treatment of laser-induced complications using only topical exosome application demonstrates the versatility and potential of this therapeutic modality. Full article

Alcohol dependency is a complex and chronic condition that negatively impacts multiple organ systems, including the skin. A key pathological factor in this process is oxidative stress, leading to progressive cellular damage, chronic inflammation, and accelerated cutaneous aging. Alcohol metabolism generates reactive oxygen species (ROS), which overwhelm endogenous antioxidant defenses and contribute to a range of skin alterations, including nonspecific changes such as xerosis, erythema, and wrinkle formation, as well as inflammatory and neoplastic skin disorders. Additionally, alcohol-induced alterations of the skin microbiome may further exacerbate skin barrier dysfunction and inflammatory responses. This review explores the biochemical mechanisms and skin microbiome alterations linking alcohol-induced oxidative stress to skin damage and disease. Furthermore, it evaluates the therapeutic potential of antioxidant-based interventions, both natural and synthetic. Antioxidants may offer protective and regenerative effects by scavenging free radicals, modulating inflammatory responses, and enhancing skin barrier function. The paper aims to provide a comprehensive overview of the molecular and microbial interplay between alcohol, oxidative stress, and skin health, while identifying future directions for targeted antioxidant therapy in individuals with alcohol dependency.

Acute Rheumatic Fever (ARF) is more common in children in the developing world. The current incidence in the United Kingdom is reported to be less than 1 in 100,000 children. It is, however, rare in the developed world, particularly in the adult Caucasian population. We present a case of ARF in a 39-year-old Caucasian female who needed multiple hospital admissions before the ARF diagnosis was made. A comprehensive, up-to-date literature review of ARF in Caucasians is lacking. Therefore, a systematic literature review (SLR) of Medline, PubMed, and Google Scholar was conducted to investigate the characteristics, management, and prognostic outcomes of new cases of ARF among Caucasians. A total of 10 cases were reported from six countries between 1990 and 2022. The mean age of patients was 33.2 (range 18–41), and most were females (6, 60%). The most common presenting symptoms were fever, arthralgia, and malaise. All patients met the modified Jones criteria for ARF diagnosis. All patients received antibiotics, with only one patient requiring corticosteroids. Two patients developed rheumatic heart disease (RHD), and none died as a result of ARF. This case-based literature review underscores the critical importance of a high index of clinical suspicion in promptly diagnosing ARF to mitigate long-term sequelae of RHD. Full article

Background/Objective: Oral lichen planus (OLP) is a chronic inflammatory disorder of the oral mucosa with unclear etiology. Increasing evidence implicates oral microbial dysbiosis in its pathogenesis, but little is known about supragingival plaque communities in relation to clinical subtypes. This cross-sectional case–control study aimed to characterize the supragingival plaque microbiota and microbial interaction networks in erosive OLP (E-OLP), non-erosive OLP (NE-OLP), and healthy controls (HCs), to elucidate microbial patterns associated with disease severity. Methods: Supragingival plaque samples were collected from 90 participants (30 per group) and analyzed using 16S rRNA gene sequencing. Alpha and beta diversity metrics, differential abundance, and co-occurrence network analyses were performed. Results: E-OLP exhibited pronounced dysbiosis, including the enrichment of pro-inflammatory taxa (e.g., Prevotella, Parvimonas) and depletion of health-associated commensals (e.g., Rothia, Capnocytophaga). Network analysis revealed the stepwise disintegration of microbial community structure from HC to NE-OLP to E-OLP, with reduced connectivity and increased dominance of pathogenic clusters in E-OLP. These microbial alterations aligned with clinical findings, as E-OLP patients showed significantly higher Reticulation/keratosis, Erythema, and Ulceration (REU) scores for erythema and ulceration compared to NE-OLP. Conclusions: Supragingival plaque dysbiosis and ecological disruption are strongly associated with OLP severity and subtype. This study highlights the utility of plaque-based microbial profiling in capturing lesion-proximal dysbiotic signals, which may complement mucosal and salivary analyses in future diagnostic frameworks. Multi-omics approaches incorporating fungal, viral, and metabolic profiling are warranted to fully elucidate host–microbe interactions in OLP. Full article

Rosacea is a chronic inflammatory skin condition characterized by persistent erythema and abnormal vascular response. Although current treatments focus on symptomatic relief, they often provide only temporary improvement and may be associated with side effects or recurrence. Cannabigerol (CBG), a non-psychoactive cannabinoid, has recently garnered attention for its pharmacological activities, including anti-inflammatory, antioxidant, neuroprotective, and skin barrier–supportive effects. However, its role in modulating pathological responses in rosacea remains unclear. In this study, we investigated the therapeutic potential of topically applied CBG in an LL-37-induced rosacea-like mouse model. Clinical and histological assessments revealed that CBG markedly reduced erythema, epidermal hyperplasia, and mast cell infiltration. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) showed downregulation of Il1b, Il4, Il6, Il13, Il22, Il31, Tlr2, Vegfa, and Mmp9. Immunohistochemistry and Western blot analyses further demonstrated suppression of CD31, vascular endothelial growth factor (VEGF), and Yes-associated protein (YAP) and transcriptional coactivator with PDZ-binding motif (TAZ), along with reduced activation of the Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway, including decreased levels of JAK1, STAT3, and phosphorylated STAT3. These findings suggest that topical CBG alleviates rosacea-like skin inflammation by targeting inflammatory and vascular pathways, including JAK/STAT and YAP/TAZ signaling. Full article

Background: Leprosy, caused by Mycobacterium leprae, presents on a spectrum ranging from tuberculoid to lepromatous disease. Borderline lepromatous leprosy represents an unstable immunological state that predisposes patients to immune-mediated reactions, including erythema nodosum leprosum (ENL), a severe inflammatory complication. Case Presentation: We report a case of a 62-year-old female with borderline lepromatous leprosy who presented with recurrent facial cellulitis and later developed disseminated ENL. She was initially diagnosed following a series of facial infections and confirmatory skin biopsy. Months later, she developed systemic inflammatory lesions consistent with ENL, requiring hospitalization. She was treated with high-dose corticosteroids for ENL and methotrexate to treat type 1 reaction and continued multidrug therapy (MDT) with minocycline, rifampin, and clarithromycin for leprosy, which led to significant clinical improvement. Conclusion: This case highlights the diagnostic challenges of leprosy in the United States and the importance of recognizing ENL as a severe immunologic complication requiring prompt intervention. A multidisciplinary approach is essential for optimal patient outcomes. Full article

Striae distensae (SD), or stretch marks, are a common aesthetic concern with limited effective treatment options. This prospective, single-center, open-label study aimed to evaluate the efficacy and safety of 1470 nm non-ablative laser therapy in improving skin texture and reducing SD dimensions. Twenty healthy female volunteers (aged 19–56) with SD of varying stages underwent three laser sessions at three-week intervals. Treatments were delivered using energy densities of 28–35 mJ per point with spot spacing of 0.8–1.2 mm, uniformly delivered over the affected SD lesions. Assessments were performed at baseline, Day 14, Day 35, Day 56–70, and Day 118–132. SD depth and width were measured using high-frequency ultrasound; aesthetic improvement was assessed using the Global Aesthetic Improvement Scale (GAIS), alongside clinical and photographic evaluations. A statistically significant, progressive reduction in SD size was observed: mean depth decreased from 0.34 mm (SD = 0.16) to 0.18 mm (SD = 0.15), and width decreased from 6.58 mm (SD = 2.65) to 4.40 mm (SD = 2.52) by Day 118–132 (p < 0.01 for both). Most participants reported improvement on GAIS at each follow-up. No severe adverse events occurred; only mild, transient erythema and edema were noted. In conclusion, 1470 nm non-ablative laser therapy showed significant efficacy and a favorable safety profile in SD treatment, offering a promising non-invasive option based on fractional thermal stimulation and selective dermal absorption.

Atopic dermatitis (AD) is a chronic inflammatory skin disease stemming from genetic susceptibility and environmental factors. It is characterized by immune dysregulation, increased mast cell activity, elevated levels of immunoglobulin E (IgE), and excessive proinflammatory mediator expression. These factors contribute to hallmark symptoms such as pruritus, erythema, and skin barrier dysfunction. In this study, we investigated the antioxidant and anti-inflammatory effects of Taraxacum mongolicum (WTM) water extract, as well as its skin barrier regulation and immune functions in AD. In the present study, we explored the therapeutic efficacy and underlying mechanisms of WTM in a BALB/c mouse model of AD induced by 2,4-dinitrochlorobenzene (DNCB). Mice were administered WTM orally or topically for 14 consecutive days. The results demonstrated that WTM treatment significantly alleviated clinical severity, showing reductions in skin lesion scores, epidermal thickness, mast cell infiltration, and scratching behavior, compared to the DNCB-treated group. Mechanistically, WTM reduced serum levels of IgE and proinflammatory cytokines (IL-4, IL-6, IL-1β, TNF-α, and IL-31) while suppressing the expression of the JAK/STAT/TSLP signaling pathway in skin tissues. Furthermore, WTM inhibited the TLR4/NF-κB and MAPK pathways and enhanced antioxidant defense by elevating superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPx) activities. These findings indicate that WTM attenuates DNCB-induced AD progression in mice, likely through the dual modulation of inflammatory signaling and oxidative stress. These findings suggest that WTM may modulate the immune response and alleviate AD symptoms by inhibiting the TLR4/NF-κB, MAPK, and JAK/STAT/TSLP pathways. Full article

Background: Oral mucositis (OM) is a common and debilitating complication of cancer therapy, particularly in patients undergoing chemotherapy and radiotherapy. It significantly impairs quality of life and may necessitate the interruption of cancer treatment. This study aimed to evaluate the efficacy and safety of OROSOL, an oral spray device, in managing oral mucositis in pediatric patients undergoing chemotherapy or radiotherapy. Methods: This randomized, double-blind, placebo-controlled clinical trial compared OROSOL to a placebo in children with oral mucositis aged 3 to 17 years. Participants were followed for 28 days with regular medical visits. The primary endpoints were changes in the Oral Assessment Guide (OAG) scores and key symptoms (mucositis score, difficulty in oral feeding, ulceration and erythema, and pain sensation). Safety was assessed via adverse events and local tolerability. Results: Both groups were demographically balanced at baseline (p > 0.6). OROSOL demonstrated significantly greater improvements in the mucositis score beginning on Day 7 (p = 0.0122) and maintained superiority through Day 28 (p = 0.0007). Notable reductions in mucositis severity were observed, with significantly faster relief in the OROSOL group compared to the placebo (p < 0.001 for most timepoints). Oral feeding difficulty also showed a marked decline, with significant improvements starting from Day 5 (p = 0.0153). Ulceration and erythema scores significantly decreased from Day 14 onwards (p = 0.0188). Pain sensation showed a marked reduction from Day 14 (p = 0.0014). No serious adverse events were reported, and tolerability was consistent across all participants. Conclusions: OROSOL has a significant impact on reducing mucositis severity, oral feeding difficulty, ulceration, erythema, and pain. Coupled with its excellent safety profile, it is a valuable therapeutic option. This treatment is particularly beneficial for pediatric patients, ensuring improved comfort and recovery without notable adverse effects. Full article
